django-admin
と manage.py
¶
django-admin
は Django の管理タスクのためのコマンドラインユーティリティです。このドキュメントでは、その機能の全体を一通り説明します。
さらに、manage.py
は各 Django プロジェクト内に自動的に作成されます。jango-admin
と同じことができますが、DJANGO_SETTINGS_MODULE
を設定することもでき、プロジェクトの settings.py
を指定できます。
Django を pip
経由でインストールした場合、 django-admin はシステムパス上に設定されているはずです。もしシステムパスにない場合、仮想環境が有効になっていることを確認してください。
通常、単体の Django プロジェクトを用いる場合、django-admin
よりも manage.py
の方が簡単に利用できます。もし複数の Django 設定ファイル間での切り替えが必要な場合は、django-admin
を DJANGO_SETTINGS_MODULE
もしくは --settings
オプションと共に利用してください。
本項ではコマンドラインの実行例は一貫して django-admin
を使用しますが、実行例は全て manage.py
もしくは python -m django
でも同様に利用可能です。
使い方¶
$ django-admin <command> [options]
$ manage.py <command> [options]
$ python -m django <command> [options]
...\> django-admin <command> [options]
...\> manage.py <command> [options]
...\> py -m django <command> [options]
command
にはこのドキュメントに一覧されたコマンドの1つでなければなりません。options
はオプションで、与えられたコマンドで利用できる 0 個以上のオプションを指定します。
ランタイムのヘルプを表示する¶
-
django-admin help
¶
django-admin help
を実行すると、使用方法の情報と、各アプリケーションが提供するコマンドのリストが表示されます。
django-admin help --commands
を実行すると、利用可能な全てのコマンドの一覧が表示されます。
django-admin help <command>
を実行すると、与えられたコマンドの説明と利用可能なオプションの一覧が表示されます。
アプリ名¶
多くのコマンドは「アプリ名」のリストを取ります。1つの「アプリ名」はモデルを含むパッケージのベースネーム (basename) となります。たとえば、INSTALLED_APPS
が文字列 'mysite.blog'
を含む場合、アプリ名は blog
になります。
バージョンを特定する¶
-
django-admin version
¶
django-admin version
を実行すると、現在の Django のバージョンが表示されます。
出力は、次のように PEP 440 で説明されたスキーマに従います。
1.4.dev17026
1.4a1
1.4
デバック出力を表示する¶
サポートされている場合に --verbosity
を使うと、django-admin
がコンソールに表示する通知とデバッグ情報の量を指定できます。
利用可能なコマンド¶
check
¶
-
django-admin check [app_label [app_label ...]]
¶
システムチェック フレームワーク を使用して、Django プロジェクト全体のよくある問題を検査します。
デフォルトでは、全てのアプリがチェックされます。アプリのサブセットをチェックするには、次のようにアプリのラベルの一覧を引数として渡します。
django-admin check auth admin myapp
-
--tag
TAGS
,
-t
TAGS
¶
システムチェック フレームワークは、:ref:`タグでカテゴリ化された <system-check-builtin-tags>`さまざまな種類のチェックを実行します。これらのタグを使用すると、特定のカテゴリ内のタグだけに実行するチェックを制限できます。たとえば、モデルと互換性のチェックだけを実行するには、次のコマンドを実行します。
django-admin check --tag models --tag compatibility
-
--database
DATABASE
¶
データベースアクセスが必要なチェックを実行するには、次のようにデータベースを指定します。
django-admin check --database default --database other
デフォルトでは、これらのチェックは実行されません。
-
--list-tags
¶
利用可能なタグを一覧します。
-
--deploy
¶
デプロイメントの設定にだけ関係のある、いくつかの追加チェックを有効化します。
このオプションはローカルの開発環境で使えますが、ローカルの開発の設定モジュールは本番の設定の多くがないかもしれないため、おそらく DJANGO_SETTINGS_MODULE
環境変数を設定するか、--settings
オプションを渡すことで、異なる設定モジュールを指定したくなるでしょう。
django-admin check --deploy --settings=production_settings
あるいは、(--settings
を省略して) 正しい設定が使用されていることを検証するために、本番かステージングのデプロイメントで直接実行することも可能です。
-

dumpdata
¶
-
django-admin dumpdata [app_label[.ModelName] [app_label[.ModelName] ...]]
¶
名前を指定したアプリケーションと関連するデータベースの中のすべてのデータを、標準出力にアウトプットします。
アプリケーション名が指定されなかった場合、インストールされたすべてのアプリケーションをダンプします。
dumpdata
のアウトプットは loaddata
に対するインプットして使用できます。
dumpdata
の出力をファイルとして保存すると、テスト や、初期データ として活用できます。
dumpdata
は、ダンプするレコードを選択するために、モデルのデフォルトのマネージャを使用することに注意してください。カスタム マネージャ をデフォルトのマネージャとして使用していて、利用できるレコードの一部をフィルタリングしている場合、必ずしもすべてのオブジェクトがダンプされるわけではありません。
-
--all
,
-a
¶
レコードをダンプする際に、フィルタリングまたは変更される可能性があるカスタム マネージャーの代わりに、Django のベース マネージャを使用します。
-
--format
FORMAT
¶
出力のシリアル化フォーマットを指定します。デフォルトは JSON です。対応フォーマットは Serialization formats に一覧があります。
-
--indent
INDENT
¶
出力で使用するインデントのスペースの数を指定します。デフォルトは None
で、全てのデータを1行で表示します。
-
--exclude
EXCLUDE
,
-e
EXCLUDE
¶
(app_label.ModelName
の形式で指定された) 特定のアプリケーションやモデルがダンプされるのを防ぎます。モデル名を指定した場合には、アプリケーション全体ではなく、そのモデルだけが除外されます。アプリケーション名とモデル名を混ぜることもできます。
複数のアプリケーションを除外したいときは、--exclude
を複数回渡してください。
django-admin dumpdata --exclude=auth --exclude=contenttypes
-
--database
DATABASE
¶
データをダンプするデータベースを指定します。デフォルトは default
です。
-
--natural-foreign
¶
natural_key()
モデルメソッドを使用して、任意の外部キーと多対多リレーションを、メソッドを定義している種類のオブジェクトにシリアル化します。contrib.auth
の Permission
オブジェクトや contrib.contenttypes
の ContentType
オブジェクトをダンプする場合、おそらくこのフラグを使う必要があります。このオプションと次のオプションの詳細については、natural keys ドキュメントを見てください。
-
--natural-primary
¶
Omits the primary key in the serialized data of this object since it can be calculated during deserialization.
-
--pks
PRIMARY_KEYS
¶
Outputs only the objects specified by a comma separated list of primary keys. This is only available when dumping one model. By default, all the records of the model are output.
-
--output
OUTPUT
,
-o
OUTPUT
¶
Specifies a file to write the serialized data to. By default, the data goes to standard output.
When this option is set and --verbosity
is greater than 0 (the default), a
progress bar is shown in the terminal.
Fixtures compression¶
The output file can be compressed with one of the bz2
, gz
, lzma
, or
xz
formats by ending the filename with the corresponding extension.
For example, to output the data as a compressed JSON file:
django-admin dumpdata -o mydata.json.gz
flush
¶
-
django-admin flush
¶
Removes all data from the database and re-executes any post-synchronization handlers. The table of which migrations have been applied is not cleared.
If you would rather start from an empty database and rerun all migrations, you
should drop and recreate the database and then run migrate
instead.
-
--noinput
,
--no-input
¶
Suppresses all user prompts.
-
--database
DATABASE
¶
Specifies the database to flush. Defaults to default
.
inspectdb
¶
-
django-admin inspectdb [table [table ...]]
¶
Introspects the database tables in the database pointed-to by the
NAME
setting and outputs a Django model module (a models.py
file) to standard output.
You may choose what tables or views to inspect by passing their names as
arguments. If no arguments are provided, models are created for views only if
the --include-views
option is used. Models for partition tables are
created on PostgreSQL if the --include-partitions
option is used.
Use this if you have a legacy database with which you'd like to use Django. The script will inspect the database and create a model for each table within it.
As you might expect, the created models will have an attribute for every field
in the table. Note that inspectdb
has a few special cases in its field-name
output:
- If
inspectdb
cannot map a column's type to a model field type, it'll useTextField
and will insert the Python comment'This field type is a guess.'
next to the field in the generated model. The recognized fields may depend on apps listed inINSTALLED_APPS
. For example,django.contrib.postgres
adds recognition for several PostgreSQL-specific field types. - If the database column name is a Python reserved word (such as
'pass'
,'class'
or'for'
),inspectdb
will append'_field'
to the attribute name. For example, if a table has a column'for'
, the generated model will have a field'for_field'
, with thedb_column
attribute set to'for'
.inspectdb
will insert the Python comment'Field renamed because it was a Python reserved word.'
next to the field.
This feature is meant as a shortcut, not as definitive model generation. After you run it, you'll want to look over the generated models yourself to make customizations. In particular, you'll need to rearrange models' order, so that models that refer to other models are ordered properly.
Django doesn't create database defaults when a
default
is specified on a model field.
Similarly, database defaults aren't translated to model field defaults or
detected in any fashion by inspectdb
.
By default, inspectdb
creates unmanaged models. That is, managed = False
in the model's Meta
class tells Django not to manage each table's creation,
modification, and deletion. If you do want to allow Django to manage the
table's lifecycle, you'll need to change the
managed
option to True
(or remove
it because True
is its default value).
Database-specific notes¶
Oracle¶
- Models are created for materialized views if
--include-views
is used.
PostgreSQL¶
- Models are created for foreign tables.
- Models are created for materialized views if
--include-views
is used. - Models are created for partition tables if
--include-partitions
is used.
-
--database
DATABASE
¶
Specifies the database to introspect. Defaults to default
.
-
--include-partitions
¶
If this option is provided, models are also created for partitions.
Only support for PostgreSQL is implemented.
-
--include-views
¶
If this option is provided, models are also created for database views.
loaddata
¶
-
django-admin loaddata fixture [fixture ...]
¶
Searches for and loads the contents of the named fixture into the database.
-
--database
DATABASE
¶
Specifies the database into which the data will be loaded. Defaults to
default
.
-
--ignorenonexistent
,
-i
¶
Ignores fields and models that may have been removed since the fixture was originally generated.
-
--app
APP_LABEL
¶
Specifies a single app to look for fixtures in rather than looking in all apps.
-
--format
FORMAT
¶
Specifies the serialization format (e.g.,
json
or xml
) for fixtures read from stdin.
-
--exclude
EXCLUDE
,
-e
EXCLUDE
¶
Excludes loading the fixtures from the given applications and/or models (in the
form of app_label
or app_label.ModelName
). Use the option multiple
times to exclude more than one app or model.
Loading fixtures from stdin
¶
You can use a dash as the fixture name to load input from sys.stdin
. For
example:
django-admin loaddata --format=json -
When reading from stdin
, the --format
option
is required to specify the serialization format
of the input (e.g., json
or xml
).
Loading from stdin
is useful with standard input and output redirections.
For example:
django-admin dumpdata --format=json --database=test app_label.ModelName | django-admin loaddata --format=json --database=prod -
The dumpdata
command can be used to generate input for loaddata
.
参考
For more detail about fixtures see the フィクスチャー topic.
makemessages
¶
-
django-admin makemessages
¶
Runs over the entire source tree of the current directory and pulls out all
strings marked for translation. It creates (or updates) a message file in the
conf/locale (in the Django tree) or locale (for project and application)
directory. After making changes to the messages files you need to compile them
with compilemessages
for use with the builtin gettext support. See
the i18n documentation for details.
This command doesn't require configured settings. However, when settings aren't
configured, the command can't ignore the MEDIA_ROOT
and
STATIC_ROOT
directories or include LOCALE_PATHS

makemigrations
¶
-
django-admin makemigrations [app_label [app_label ...]]
¶
検出されたモデルの変更に基づいて、新しいマイグレーションを作成します。マイグレーションおよびそのアプリとの関係は、詳しくは the migrations documentation1 で説明しています。
1つ以上のアプリ名を引数として与えると、作成するマイグレーションを、指定されたアプリとそれに必要な依存関係 (たとえば、外部キーで繋がれた他のテーブルなど) に限定されます。
マイグレーションを migrations
ディレクトリが存在しないアプリに追加するには、makemigrations
にアプリの app_label
を付けて実行します。
-

-
--dry-run
¶
実際にマイグレーションをディスクには書き込まず、作成される予定のマイグレーションを表示します。このオプションを --verbosity 3
オプションと併用することで、書き込まれる予定のマイグレーションファイルの内容そのものを表示することができます。
-
--merge
¶
マイグレーションで発生するコンフリクトの修復を有効にする
-
--name
NAME
,
-n
NAME
¶
Allows naming the generated migration(s) instead of using a generated name. The name must be a valid Python identifier.
-
--no-header
¶
Generate migration files without Django version and timestamp header.
-
--check
¶
Makes makemigrations
exit with a non-zero status when model changes without
migrations are detected. Implies --dry-run
.
In older versions, the missing migrations were also created when using the
--check
option.
-
--scriptable
¶
Diverts log output and input prompts to stderr
, writing only paths of
generated migration files to stdout
.
-
--update
¶
Merges model changes into the latest migration and optimize the resulting operations.
The updated migration will have a generated name. In order to preserve the
previous name, set it using --name
.
migrate
¶
-
django-admin migrate [app_label] [migration_name]
¶
データベースの状態を、現在のモデルとマイグレーションのセットを基づいて同期します。マイグレーションおよびそのアプリとの関係については、詳しくは the migrations documentation で説明しています。
このコマンドの動作は、次のように与えられた引数によって変化します。
- 引数なし: 全てのアプリが、それぞれが持つマイグレーションを全て実行します。
<app_label>
: 指定したアプリに最新のマイグレーションまで実行させます。依存関係によっては、他のアプリのマイグレーションも実行される場合もあります<app_label> <migrationname>
: Brings the database schema to a state where the named migration is applied, but no later migrations in the same app are applied. This may involve unapplying migrations if you have previously migrated past the named migration. You can use a prefix of the migration name, e.g.0001
, as long as it's unique for the given app name. Use the namezero
to migrate all the way back i.e. to revert all applied migrations for an app.
警告
When unapplying migrations, all dependent migrations will also be
unapplied, regardless of <app_label>
. You can use --plan
to check
which migrations will be unapplied.
-
--database
DATABASE
¶
マイグレートするデータベースを指定します。デフォルトは default
です。
-
--fake
¶
Marks the migrations up to the target one (following the rules above) as applied, but without actually running the SQL to change your database schema.
This is intended for advanced users to manipulate the
current migration state directly if they're manually applying changes;
be warned that using --fake
runs the risk of putting the migration state
table into a state where manual recovery will be needed to make migrations
run correctly.
-
--fake-initial
¶
Allows Django to skip an app's initial migration if all database tables with
the names of all models created by all
CreateModel
operations in that
migration already exist. This option is intended for use when first running
migrations against a database that preexisted the use of migrations. This
option does not, however, check for matching database schema beyond matching
table names and so is only safe to use if you are confident that your existing
schema matches what is recorded in your initial migration.
-
--plan
¶
Shows the migration operations that will be performed for the given migrate
command.
-
--run-syncdb
¶
Allows creating tables for apps without migrations. While this isn't recommended, the migrations framework is sometimes too slow on large projects with hundreds of models.
-
--noinput
,
--no-input
¶
Suppresses all user prompts. An example prompt is asking about removing stale content types.
-
--check
¶
Makes migrate
exit with a non-zero status when unapplied migrations are
detected.
-
--prune
¶
Deletes nonexistent migrations from the django_migrations
table. This is
useful when migration files replaced by a squashed migration have been removed.
See Squashing migrations for more details.
optimizemigration
¶
-
django-admin optimizemigration app_label migration_name
¶
Optimizes the operations for the named migration and overrides the existing
file. If the migration contains functions that must be manually copied, the
command creates a new migration file suffixed with _optimized
that is meant
to replace the named migration.
-
--check
¶
Makes optimizemigration
exit with a non-zero status when a migration can be
optimized.
runserver
¶
-
django-admin runserver [addrport]
¶
Starts a lightweight development web server on the local machine. By default,
the server runs on port 8000 on the IP address 127.0.0.1
. You can pass in an
IP address and port number explicitly.
If you run this script as a user with normal privileges (recommended), you might not have access to start a port on a low port number. Low port numbers are reserved for the superuser (root).
This server uses the WSGI application object specified by the
WSGI_APPLICATION
setting.
DO NOT USE THIS SERVER IN A PRODUCTION SETTING. It has not gone through security audits or performance tests. (And that's how it's gonna stay. We're in the business of making web frameworks, not web servers, so improving this server to be able to handle a production environment is outside the scope of Django.)
The development server automatically reloads Python code for each request, as needed. You don't need to restart the server for code changes to take effect. However, some actions like adding files don't trigger a restart, so you'll have to restart the server in these cases.
If you're using Linux or MacOS and install both pywatchman and the
Watchman service, kernel signals will be used to autoreload the server
(rather than polling file modification timestamps each second). This offers
better performance on large projects, reduced response time after code changes,
more robust change detection, and a reduction in power usage. Django supports
pywatchman
1.2.0 and higher.
Large directories with many files may cause performance issues
When using Watchman with a project that includes large non-Python
directories like node_modules
, it's advisable to ignore this directory
for optimal performance. See the watchman documentation for information
on how to do this.
Watchman timeout
-
DJANGO_WATCHMAN_TIMEOUT
¶
The default timeout of Watchman
client is 5 seconds. You can change it
by setting the DJANGO_WATCHMAN_TIMEOUT
environment variable.
When you start the server, and each time you change Python code while the
server is running, the system check framework will check your entire Django
project for some common errors (see the check
command). If any
errors are found, they will be printed to standard output. You can use the
--skip-checks
option to skip running system checks.
You can run as many concurrent servers as you want, as long as they're on
separate ports by executing django-admin runserver
more than once.
Note that the default IP address, 127.0.0.1
, is not accessible from other
machines on your network. To make your development server viewable to other
machines on the network, use its own IP address (e.g. 192.168.2.1
), 0
(shortcut for 0.0.0.0
), 0.0.0.0
, or ::
(with IPv6 enabled).
ブラケットで囲まれた IPv6 アドレス (例 [200a::1]:8000
) を与えることもできます。その場合には、IPv6 のサポートが自動的に有効になります。
ホスト名には ASCII 文字のみからなる文字列も使用できます。
If the staticfiles contrib app is enabled
(default in new projects) the runserver
command will be overridden
with its own runserver command.
Logging of each request and response of the server is sent to the django.server logger.
-
--noreload
¶
Disables the auto-reloader. This means any Python code changes you make while the server is running will not take effect if the particular Python modules have already been loaded into memory.
-
--nothreading
¶
開発サーバーでのスレッドの使用を無効にします。デフォルトではサーバーはマルチスレッドです。
-
--ipv6
,
-6
¶
開発用サーバーで IPv6 を使用します。これにより、デフォルトの IP アドレスが 127.0.0.1
から ::1
に変わります。
異なるポートとアドレスを使用する場合の引数例¶
Port 8000 on IP address 127.0.0.1
:
django-admin runserver
Port 8000 on IP address 1.2.3.4
:
django-admin runserver 1.2.3.4:8000
Port 7000 on IP address 127.0.0.1
:
django-admin runserver 7000
Port 7000 on IP address 1.2.3.4
:
django-admin runserver 1.2.3.4:7000
Port 8000 on IPv6 address ::1
:
django-admin runserver -6
Port 7000 on IPv6 address ::1
:
django-admin runserver -6 7000
Port 7000 on IPv6 address 2001:0db8:1234:5678::9
:
django-admin runserver [2001:0db8:1234:5678::9]:7000
Port 8000 on IPv4 address of host localhost
:
django-admin runserver localhost:8000
Port 8000 on IPv6 address of host localhost
:
django-admin runserver -6 localhost:8000
開発用サーバーで静的 (static) ファイルを配信する¶
By default, the development server doesn't serve any static files for your site
(such as CSS files, images, things under MEDIA_URL
and so forth). If
you want to configure Django to serve static media, read
静的ファイル (画像、JavaScript、CSS など) を管理する.
Serving with ASGI in development¶
Django's runserver
command provides a WSGI server. In order to run under
ASGI you will need to use an ASGI server.
The Django Daphne project provides Integration with runserver that you can use.
sendtestemail
¶
-
django-admin sendtestemail [email [email ...]]
¶
Sends a test email (to confirm email sending through Django is working) to the recipient(s) specified. For example:
django-admin sendtestemail foo@example.com bar@example.com
いくつかのオプションがあるので、次のようにそれらを任意に組み合わせて使用できます。
-
--managers
¶
mail_managers()
を使用して MANAGERS
で指定されたメールアドレスにメールします。
-
--admins
¶
mail_admins()
を使用して ADMINS
で指定されたメールアドレスにメールします。
shell
¶
-
django-admin shell
¶
Python のインタラクティブ・インタープリタを開始します。
-
--interface
{ipython,bpython,python}
,
-i
{ipython,bpython,python}
¶
使用するシェルを指定します。デフォルトでは、Django はインストールされている場合には IPython または bpython を使用します。両方インストールされている場合には、次のようにして使いたいシェルを指定してください。
IPython:
django-admin shell -i ipython
bpython:
django-admin shell -i bpython
If you have a "rich" shell installed but want to force use of the "plain"
Python interpreter, use python
as the interface name, like so:
django-admin shell -i python
-
--nostartup
¶
Disables reading the startup script for the "plain" Python interpreter. By
default, the script pointed to by the PYTHONSTARTUP
environment
variable or the ~/.pythonrc.py
script is read.
-
--command
COMMAND
,
-c
COMMAND
¶
Lets you pass a command as a string to execute it as Django, like so:
django-admin shell --command="import django; print(django.__version__)"
You can also pass code in on standard input to execute it. For example:
$ django-admin shell <<EOF
> import django
> print(django.__version__)
> EOF
On Windows, the REPL is output due to implementation limits of
select.select()
on that platform.
showmigrations
¶
-
django-admin showmigrations [app_label [app_label ...]]
¶
Shows all migrations in a project. You can choose from one of two formats:
-
--list
,
-l
¶
Lists all of the apps Django knows about, the migrations available for each
app, and whether or not each migration is applied (marked by an [X]
next to
the migration name). For a --verbosity
of 2 and above, the applied
datetimes are also shown.
Apps without migrations are also listed, but have (no migrations)
printed
under them.
This is the default output format.
-
--plan
,
-p
¶
Shows the migration plan Django will follow to apply migrations. Like
--list
, applied migrations are marked by an [X]
. For a --verbosity
of 2 and above, all dependencies of a migration will also be shown.
app_label
s arguments limit the output, however, dependencies of provided
apps may also be included.
-
--database
DATABASE
¶
Specifies the database to examine. Defaults to default
.
sqlflush
¶
-
django-admin sqlflush
¶
Prints the SQL statements that would be executed for the flush
command.
-
--database
DATABASE
¶
Specifies the database for which to print the SQL. Defaults to default
.
sqlmigrate
¶
-
django-admin sqlmigrate app_label migration_name
¶
Prints the SQL for the named migration. This requires an active database connection, which it will use to resolve constraint names; this means you must generate the SQL against a copy of the database you wish to later apply it on.
Note that sqlmigrate
doesn't colorize its output.
-
--backwards
¶
Generates the SQL for unapplying the migration. By default, the SQL created is for running the migration in the forwards direction.
-
--database
DATABASE
¶
Specifies the database for which to generate the SQL. Defaults to default
.
sqlsequencereset
¶
-
django-admin sqlsequencereset app_label [app_label ...]
¶
Prints the SQL statements for resetting sequences for the given app name(s).
Sequences are indexes used by some database engines to track the next available number for automatically incremented fields.
Use this command to generate SQL which will fix cases where a sequence is out of sync with its automatically incremented field data.
-
--database
DATABASE
¶
Specifies the database for which to print the SQL. Defaults to default
.
squashmigrations
¶
-
django-admin squashmigrations app_label [start_migration_name] migration_name
¶
Squashes the migrations for app_label
up to and including migration_name
down into fewer migrations, if possible. The resulting squashed migrations
can live alongside the unsquashed ones safely. For more information,
please read Squashing migrations.
When start_migration_name
is given, Django will only include migrations
starting from and including this migration. This helps to mitigate the
squashing limitation of RunPython
and
django.db.migrations.operations.RunSQL
migration operations.
-
--no-optimize
¶
Disables the optimizer when generating a squashed migration. By default, Django will try to optimize the operations in your migrations to reduce the size of the resulting file. Use this option if this process is failing or creating incorrect migrations, though please also file a Django bug report about the behavior, as optimization is meant to be safe.
-
--noinput
,
--no-input
¶
Suppresses all user prompts.
-
--squashed-name
SQUASHED_NAME
¶
Sets the name of the squashed migration. When omitted, the name is based on the
first and last migration, with _squashed_
in between.
-
--no-header
¶
Generate squashed migration file without Django version and timestamp header.
startapp
¶
-
django-admin startapp name [directory]
¶
Creates a Django app directory structure for the given app name in the current directory or the given destination.
By default, the new directory contains a
models.py
file and other app template files. If only the app name is given,
the app directory will be created in the current working directory.
If the optional destination is provided, Django will use that existing directory rather than creating a new one. You can use '.' to denote the current working directory.
例えば:
django-admin startapp myapp /Users/jezdez/Code/myapp
-
--template
TEMPLATE
¶
Provides the path to a directory with a custom app template file, or a path to
an uncompressed archive (.tar
) or a compressed archive (.tar.gz
,
.tar.bz2
, .tar.xz
, .tar.lzma
, .tgz
, .tbz2
, .txz
,
.tlz
, .zip
) containing the app template files.
For example, this would look for an app template in the given directory when
creating the myapp
app:
django-admin startapp --template=/Users/jezdez/Code/my_app_template myapp
Django will also accept URLs (http
, https
, ftp
) to compressed
archives with the app template files, downloading and extracting them on the
fly.
For example, taking advantage of GitHub's feature to expose repositories as zip files, you can use a URL like:
django-admin startapp --template=https://github.com/githubuser/django-app-template/archive/main.zip myapp
-
--extension
EXTENSIONS
,
-e
EXTENSIONS
¶
Specifies which file extensions in the app template should be rendered with the
template engine. Defaults to py
.
-
--name
FILES
,
-n
FILES
¶
Specifies which files in the app template (in addition to those matching
--extension
) should be rendered with the template engine. Defaults to an
empty list.
-
--exclude
DIRECTORIES
,
-x
DIRECTORIES
¶
Specifies which directories in the app template should be excluded, in addition
to .git
and __pycache__
. If this option is not provided, directories
named __pycache__
or starting with .
will be excluded.
The template context
used for all matching
files is:
- Any option passed to the
startapp
command (among the command's supported options) app_name
-- the app name as passed to the commandapp_directory
-- the full path of the newly created appcamel_case_app_name
-- the app name in camel case formatdocs_version
-- the version of the documentation:'dev'
or'1.x'
django_version
-- the version of Django, e.g.'2.0.3'
警告
When the app template files are rendered with the Django template
engine (by default all *.py
files), Django will also replace all
stray template variables contained. For example, if one of the Python files
contains a docstring explaining a particular feature related
to template rendering, it might result in an incorrect example.
To work around this problem, you can use the templatetag
template tag to "escape" the various parts of the template syntax.
In addition, to allow Python template files that contain Django template
language syntax while also preventing packaging systems from trying to
byte-compile invalid *.py
files, template files ending with .py-tpl
will be renamed to .py
.
警告
The contents of custom app (or project) templates should always be audited before use: Such templates define code that will become part of your project, and this means that such code will be trusted as much as any app you install, or code you write yourself. Further, even rendering the templates is, effectively, executing code that was provided as input to the management command. The Django template language may provide wide access into the system, so make sure any custom template you use is worthy of your trust.
startproject
¶
-
django-admin startproject name [directory]
¶
Creates a Django project directory structure for the given project name in the current directory or the given destination.
By default, the new directory contains
manage.py
and a project package (containing a settings.py
and other
files).
If only the project name is given, both the project directory and project
package will be named <projectname>
and the project directory
will be created in the current working directory.
If the optional destination is provided, Django will use that existing
directory as the project directory, and create manage.py
and the project
package within it. Use '.' to denote the current working directory.
例えば:
django-admin startproject myproject /Users/jezdez/Code/myproject_repo
-
--template
TEMPLATE
¶
Specifies a directory, file path, or URL of a custom project template. See the
startapp --template
documentation for examples and usage.
-
--extension
EXTENSIONS
,
-e
EXTENSIONS
¶
Specifies which file extensions in the project template should be rendered with
the template engine. Defaults to py
.
-
--name
FILES
,
-n
FILES
¶
Specifies which files in the project template (in addition to those matching
--extension
) should be rendered with the template engine. Defaults to an
empty list.
-
--exclude
DIRECTORIES
,
-x
DIRECTORIES
¶
Specifies which directories in the project template should be excluded, in
addition to .git
and __pycache__
. If this option is not provided,
directories named __pycache__
or starting with .
will be excluded.
The template context
used is:
- Any option passed to the
startproject
command (among the command's supported options) project_name
-- the project name as passed to the commandproject_directory
-- the full path of the newly created projectsecret_key
-- a random key for theSECRET_KEY
settingdocs_version
-- the version of the documentation:'dev'
or'1.x'
django_version
-- the version of Django, e.g.'2.0.3'
Please also see the rendering warning and
trusted code warning as mentioned for
startapp
.
test
¶
-
django-admin test [test_label [test_label ...]]
¶
Runs tests for all installed apps. See Django におけるテスト for more information.
-
--failfast
¶
Stops running tests and reports the failure immediately after a test fails.
-
--testrunner
TESTRUNNER
¶
Controls the test runner class that is used to execute tests. This value
overrides the value provided by the TEST_RUNNER
setting.
-
--noinput
,
--no-input
¶
Suppresses all user prompts. A typical prompt is a warning about deleting an existing test database.
テストランナーのオプション¶
The test
command receives options on behalf of the specified
--testrunner
. These are the options of the default test runner:
DiscoverRunner
.
-
--keepdb
¶
Preserves the test database between test runs. This has the advantage of
skipping both the create and destroy actions which can greatly decrease the
time to run tests, especially those in a large test suite. If the test database
does not exist, it will be created on the first run and then preserved for each
subsequent run. Unless the MIGRATE
test setting is
False
, any unapplied migrations will also be applied to the test database
before running the test suite.
-
--shuffle
[SEED]
¶
Randomizes the order of tests before running them. This can help detect tests that aren't properly isolated. The test order generated by this option is a deterministic function of the integer seed given. When no seed is passed, a seed is chosen randomly and printed to the console. To repeat a particular test order, pass a seed. The test orders generated by this option preserve Django's guarantees on test order. They also keep tests grouped by test case class.
The shuffled orderings also have a special consistency property useful when narrowing down isolation issues. Namely, for a given seed and when running a subset of tests, the new order will be the original shuffling restricted to the smaller set. Similarly, when adding tests while keeping the seed the same, the order of the original tests will be the same in the new order.
-
--reverse
,
-r
¶
Sorts test cases in the opposite execution order. This may help in debugging
the side effects of tests that aren't properly isolated. Grouping by test
class is preserved when using this option. This can be used
in conjunction with --shuffle
to reverse the order for a particular seed.
-
--debug-mode
¶
Sets the DEBUG
setting to True
prior to running tests. This may
help troubleshoot test failures.
-
--debug-sql
,
-d
¶
Enables SQL logging for failing tests. If
--verbosity
is 2
, then queries in passing tests are also output.
-
--parallel
[N]
¶
-
DJANGO_TEST_PROCESSES
¶
Runs tests in separate parallel processes. Since modern processors have multiple cores, this allows running tests significantly faster.
Using --parallel
without a value, or with the value auto
, runs one test
process per core according to multiprocessing.cpu_count()
. You can
override this by passing the desired number of processes, e.g.
--parallel 4
, or by setting the DJANGO_TEST_PROCESSES
environment
variable.
Django distributes test cases — unittest.TestCase
subclasses — to
subprocesses. If there are fewer test cases than configured processes, Django
will reduce the number of processes accordingly.
各プロセスごとに個別のデータベースを持つため、異なるテストケースが同じリソースにアクセスしないように注意が必要です。たとえば、複数のテストケースがファイルシステムにアクセスするような場合には、各テストケースごとに個別に一時ディレクトリを作成するようにしてください。
注釈
If you have test classes that cannot be run in parallel, you can use
SerializeMixin
to run them sequentially. See Enforce running test
classes sequentially.
This option requires the third-party tblib
package to display tracebacks
correctly:
$ python -m pip install tblib
This feature isn't available on Windows. It doesn't work with the Oracle database backend either.
If you want to use pdb
while debugging tests, you must disable parallel
execution (--parallel=1
). You'll see something like bdb.BdbQuit
if you
don't.
警告
When test parallelization is enabled and a test fails, Django may be unable to display the exception traceback. This can make debugging difficult. If you encounter this problem, run the affected test without parallelization to see the traceback of the failure.
This is a known limitation. It arises from the need to serialize objects in order to exchange them between processes. See What can be pickled and unpickled? for details.
-
--tag
TAGS
¶
Runs only tests marked with the specified tags.
May be specified multiple times and combined with test --exclude-tag
.
Tests that fail to load are always considered matching.
-
--exclude-tag
EXCLUDE_TAGS
¶
Excludes tests marked with the specified tags.
May be specified multiple times and combined with test --tag
.
-
-k
TEST_NAME_PATTERNS
¶
Runs test methods and classes matching test name patterns, in the same way as
unittest's -k option
. Can be specified multiple times.
-
--pdb
¶
Spawns a pdb
debugger at each test error or failure. If you have it
installed, ipdb
is used instead.
-
--buffer
,
-b
¶
Discards output (stdout
and stderr
) for passing tests, in the same way
as unittest's --buffer option
.
-
--no-faulthandler
¶
Django automatically calls faulthandler.enable()
when starting the
tests, which allows it to print a traceback if the interpreter crashes. Pass
--no-faulthandler
to disable this behavior.
-
--timing
¶
Outputs timings, including database setup and total run time.
testserver
¶
-
django-admin testserver [fixture [fixture ...]]
¶
Runs a Django development server (as in runserver
) using data from
the given fixture(s).
For example, this command:
django-admin testserver mydata.json
...would perform the following steps:
- Create a test database, as described in test データベース.
- Populate the test database with fixture data from the given fixtures.
(For more on fixtures, see the documentation for
loaddata
above.) - Runs the Django development server (as in
runserver
), pointed at this newly created test database instead of your production database.
This is useful in a number of ways:
- When you're writing unit tests of how your views
act with certain fixture data, you can use
testserver
to interact with the views in a web browser, manually. - Let's say you're developing your Django application and have a "pristine"
copy of a database that you'd like to interact with. You can dump your
database to a fixture (using the
dumpdata
command, explained above), then usetestserver
to run your web application with that data. With this arrangement, you have the flexibility of messing up your data in any way, knowing that whatever data changes you're making are only being made to a test database.
Note that this server does not automatically detect changes to your Python
source code (as runserver
does). It does, however, detect changes to
templates.
-
--addrport
ADDRPORT
¶
Specifies a different port, or IP address and port, from the default of
127.0.0.1:8000
. This value follows exactly the same format and serves
exactly the same function as the argument to the runserver
command.
例:
To run the test server on port 7000 with fixture1
and fixture2
:
django-admin testserver --addrport 7000 fixture1 fixture2
django-admin testserver fixture1 fixture2 --addrport 7000
(The above statements are equivalent. We include both of them to demonstrate that it doesn't matter whether the options come before or after the fixture arguments.)
To run on 1.2.3.4:7000 with a test
fixture:
django-admin testserver --addrport 1.2.3.4:7000 test
-
--noinput
,
--no-input
¶
Suppresses all user prompts. A typical prompt is a warning about deleting an existing test database.
Commands provided by applications¶
Some commands are only available when the django.contrib
application that
implements them has been
enabled
. This section describes them grouped by
their application.
django.contrib.auth
¶
changepassword
¶
-
django-admin changepassword [<username>]
¶
This command is only available if Django's authentication system (django.contrib.auth
) is installed.
Allows changing a user's password. It prompts you to enter a new password twice for the given user. If the entries are identical, this immediately becomes the new password. If you do not supply a user, the command will attempt to change the password whose username matches the current user.
-
--database
DATABASE
¶
Specifies the database to query for the user. Defaults to default
.
Example usage:
django-admin changepassword ringo
createsuperuser
¶
-
django-admin createsuperuser
¶
-
DJANGO_SUPERUSER_PASSWORD
¶
This command is only available if Django's authentication system (django.contrib.auth
) is installed.
superuser アカウント (すべての権限を持ったユーザー) を作成します。このコマンドは、最初に superuser アカウントを作成する場合や、サイトの superuser アカウントをプログラムから自動生成する必要がある場合に便利です。
When run interactively, this command will prompt for a password for
the new superuser account. When run non-interactively, you can provide
a password by setting the DJANGO_SUPERUSER_PASSWORD
environment
variable. Otherwise, no password will be set, and the superuser account will
not be able to log in until a password has been manually set for it.
In non-interactive mode, the
USERNAME_FIELD
and required
fields (listed in
REQUIRED_FIELDS
) fall back to
DJANGO_SUPERUSER_<uppercase_field_name>
environment variables, unless they
are overridden by a command line argument. For example, to provide an email
field, you can use DJANGO_SUPERUSER_EMAIL
environment variable.
-
--noinput
,
--no-input
¶
Suppresses all user prompts. If a suppressed prompt cannot be resolved automatically, the command will exit with error code 1.
-
--username
USERNAME
¶
-
--email
EMAIL
¶
The username and email address for the new account can be supplied by
using the --username
and --email
arguments on the command
line. If either of those is not supplied, createsuperuser
will prompt for
it when running interactively.
-
--database
DATABASE
¶
Specifies the database into which the superuser object will be saved.
You can subclass the management command and override get_input_data()
if you
want to customize data input and validation. Consult the source code for
details on the existing implementation and the method's parameters. For example,
it could be useful if you have a ForeignKey
in
REQUIRED_FIELDS
and want to
allow creating an instance instead of entering the primary key of an existing
instance.
django.contrib.contenttypes
¶
remove_stale_contenttypes
¶
-
django-admin remove_stale_contenttypes
¶
This command is only available if Django's contenttypes app (django.contrib.contenttypes
) is installed.
Deletes stale content types (from deleted models) in your database. Any objects that depend on the deleted content types will also be deleted. A list of deleted objects will be displayed before you confirm it's okay to proceed with the deletion.
-
--database
DATABASE
¶
Specifies the database to use. Defaults to default
.
-
--include-stale-apps
¶
Deletes stale content types including ones from previously installed apps that
have been removed from INSTALLED_APPS
. Defaults to False
.
django.contrib.gis
¶
ogrinspect
¶
このコマンドは、GeoDjango (django.contrib.gis
) がインストールされている場合のみ使用できます。
GeoDjango のドキュメントの description
を参照してください。
django.contrib.sessions
¶
django.contrib.sitemaps
¶
ping_google
¶
このコマンドは、Sitemaps framework (django.contrib.sitemaps
) がインストールされている場合のみ使用できます。
Sitemaps ドのキュメントの description
を参照してください。
django.contrib.staticfiles
¶
collectstatic
¶
This command is only available if the static files application (django.contrib.staticfiles
) is installed.
Please refer to its description
in the
staticfiles documentation.
findstatic
¶
This command is only available if the static files application (django.contrib.staticfiles
) is installed.
Please refer to its description
in the staticfiles documentation.
Default options¶
Although some commands may allow their own custom options, every command allows for the following options by default:
-
--pythonpath
PYTHONPATH
¶
Adds the given filesystem path to the Python import search path. If this
isn't provided, django-admin
will use the PYTHONPATH
environment
variable.
This option is unnecessary in manage.py
, because it takes care of setting
the Python path for you.
Example usage:
django-admin migrate --pythonpath='/home/djangoprojects/myproject'
-
--settings
SETTINGS
¶
Specifies the settings module to use. The settings module should be in Python
package syntax, e.g. mysite.settings
. If this isn't provided,
django-admin
will use the DJANGO_SETTINGS_MODULE
environment
variable.
This option is unnecessary in manage.py
, because it uses
settings.py
from the current project by default.
Example usage:
django-admin migrate --settings=mysite.settings
-
--traceback
¶
Displays a full stack trace when a CommandError
is raised. By default, django-admin
will show an error message when a
CommandError
occurs and a full stack trace for any other exception.
This option is ignored by runserver
.
Example usage:
django-admin migrate --traceback
-
--verbosity
{0,1,2,3}
,
-v
{0,1,2,3}
¶
Specifies the amount of notification and debug information that a command should print to the console.
0
means no output.1
means normal output (default).2
means verbose output.3
means very verbose output.
This option is ignored by runserver
.
Example usage:
django-admin migrate --verbosity 2
-
--no-color
¶
Disables colorized command output. Some commands format their output to be colorized. For example, errors will be printed to the console in red and SQL statements will be syntax highlighted.
Example usage:
django-admin runserver --no-color
-
--force-color
¶
Forces colorization of the command output if it would otherwise be disabled as discussed in Syntax coloring. For example, you may want to pipe colored output to another command.
-
--skip-checks
¶
Skips running system checks prior to running the command. This option is only
available if the
requires_system_checks
command
attribute is not an empty list or tuple.
Example usage:
django-admin migrate --skip-checks
Extra niceties¶
Syntax coloring¶
-
DJANGO_COLORS
¶
The django-admin
/ manage.py
commands will use pretty
color-coded output if your terminal supports ANSI-colored output. It
won't use the color codes if you're piping the command's output to
another program unless the --force-color
option is used.
Windows support¶
On Windows 10, the Windows Terminal application, VS Code, and PowerShell (where virtual terminal processing is enabled) allow colored output, and are supported by default.
Under Windows, the legacy cmd.exe
native console doesn't support ANSI
escape sequences so by default there is no color output. In this case either of
two third-party libraries are needed:
Install colorama, a Python package that translates ANSI color codes into Windows API calls. Django commands will detect its presence and will make use of its services to color output just like on Unix-based platforms.
colorama
can be installed via pip:...\> py -m pip install colorama
Install ANSICON, a third-party tool that allows
cmd.exe
to process ANSI color codes. Django commands will detect its presence and will make use of its services to color output just like on Unix-based platforms.
Other modern terminal environments on Windows, that support terminal colors,
but which are not automatically detected as supported by Django, may "fake" the
installation of ANSICON
by setting the appropriate environmental variable,
ANSICON="on"
.
Custom colors¶
The colors used for syntax highlighting can be customized. Django ships with three color palettes:
dark
, suited to terminals that show white text on a black background. This is the default palette.light
, suited to terminals that show black text on a white background.nocolor
, which disables syntax highlighting.
You select a palette by setting a DJANGO_COLORS
environment
variable to specify the palette you want to use. For example, to
specify the light
palette under a Unix or OS/X BASH shell, you
would run the following at a command prompt:
export DJANGO_COLORS="light"
You can also customize the colors that are used. Django specifies a number of roles in which color is used:
error
- A major error.notice
- A minor error.success
- A success.warning
- A warning.sql_field
- The name of a model field in SQL.sql_coltype
- The type of a model field in SQL.sql_keyword
- An SQL keyword.sql_table
- The name of a model in SQL.http_info
- A 1XX HTTP Informational server response.http_success
- A 2XX HTTP Success server response.http_not_modified
- A 304 HTTP Not Modified server response.http_redirect
- A 3XX HTTP Redirect server response other than 304.http_not_found
- A 404 HTTP Not Found server response.http_bad_request
- A 4XX HTTP Bad Request server response other than 404.http_server_error
- A 5XX HTTP Server Error response.migrate_heading
- A heading in a migrations management command.migrate_label
- A migration name.
Each of these roles can be assigned a specific foreground and background color, from the following list:
black
red
green
yellow
blue
magenta
cyan
white
Each of these colors can then be modified by using the following display options:
bold
underscore
blink
reverse
conceal
A color specification follows one of the following patterns:
role=fg
role=fg/bg
role=fg,option,option
role=fg/bg,option,option
where role
is the name of a valid color role, fg
is the
foreground color, bg
is the background color and each option
is one of the color modifying options. Multiple color specifications
are then separated by a semicolon. For example:
export DJANGO_COLORS="error=yellow/blue,blink;notice=magenta"
would specify that errors be displayed using blinking yellow on blue, and notices displayed using magenta. All other color roles would be left uncolored.
Colors can also be specified by extending a base palette. If you put a palette name in a color specification, all the colors implied by that palette will be loaded. So:
export DJANGO_COLORS="light;error=yellow/blue,blink;notice=magenta"
would specify the use of all the colors in the light color palette, except for the colors for errors and notices which would be overridden as specified.
Bash による補完¶
If you use the Bash shell, consider installing the Django bash completion
script, which lives in extras/django_bash_completion in the Django source
distribution. It enables tab-completion of django-admin
and
manage.py
commands, so you can, for instance...
- まず、
django-admin
とタイプします。 - [TAB] キーをクリックし、利用できるオプション一覧を表示します。
sql
とタイプし、[TAB] キーを押すと、名前がsql
で始まるオプション一覧が表示されます。

Black formatting¶
The Python files created by startproject
, startapp
,
optimizemigration
, makemigrations
, and
squashmigrations
are formatted using the black
command if it is
present on your PATH
.
If you have black
globally installed, but do not wish it used for the
current project, you can set the PATH
explicitly:
PATH=path/to/venv/bin django-admin makemigrations
For commands using stdout
you can pipe the output to black
if needed:
django-admin inspectdb | black -
Running management commands from your code¶
-
django.core.management.
call_command
(name, *args, **options)¶
To call a management command from code use call_command
.
name
- the name of the command to call or a command object. Passing the name is preferred unless the object is required for testing.
*args
- a list of arguments accepted by the command. Arguments are passed to the
argument parser, so you can use the same style as you would on the command
line. For example,
call_command('flush', '--verbosity=0')
. **options
- named options accepted on the command-line. Options are passed to the command
without triggering the argument parser, which means you'll need to pass the
correct type. For example,
call_command('flush', verbosity=0)
(zero must be an integer rather than a string).
例:
from django.core import management
from django.core.management.commands import loaddata
management.call_command("flush", verbosity=0, interactive=False)
management.call_command("loaddata", "test_data", verbosity=0)
management.call_command(loaddata.Command(), "test_data", verbosity=0)
Note that command options that take no arguments are passed as keywords
with True
or False
, as you can see with the interactive
option above.
Named arguments can be passed by using either one of the following syntaxes:
# Similar to the command line
management.call_command("dumpdata", "--natural-foreign")
# Named argument similar to the command line minus the initial dashes and
# with internal dashes replaced by underscores
management.call_command("dumpdata", natural_foreign=True)
# `use_natural_foreign_keys` is the option destination variable
management.call_command("dumpdata", use_natural_foreign_keys=True)
Some command options have different names when using call_command()
instead
of django-admin
or manage.py
. For example, django-admin
createsuperuser --no-input
translates to call_command('createsuperuser',
interactive=False)
. To find what keyword argument name to use for
call_command()
, check the command's source code for the dest
argument
passed to parser.add_argument()
.
Command options which take multiple options are passed a list:
management.call_command("dumpdata", exclude=["contenttypes", "auth"])
The return value of the call_command()
function is the same as the return
value of the handle()
method of the command.
Output redirection¶
Note that you can redirect standard output and error streams as all commands
support the stdout
and stderr
options. For example, you could write:
with open("/path/to/command_output", "w") as f:
management.call_command("dumpdata", stdout=f)
