January 2, 2016

Django 1.9.1 corrige plusieurs bogues de la version 1.9.

Correction de bogues

• Correction de BaseCache.get_or_set() avec le moteur DummyCache (#25840).

• Fixed a regression in FormMixin causing forms to be validated twice (#25548, #26018).

• Correction du plantage d’un contrôle système avec des champs ArrayField imbriqués (#25867).

• Correction d’un bogue d’état lors de l’inversion d’une opération de migration SeparateDatabaseAndState (#25896).

• Correction d’une régression dans CommonMiddleware faisant que les contrôles If-None-Match renvoyaient toujours une réponse HTTP 200 (#25900).

• Correction d’un index varchar/text_pattern_ops manquant sur les champs CharField et TextField lors de l’utilisation de AlterField avec PostgreSQL (#25412).

• Fixed admin’s delete confirmation page’s summary counts of related objects (#25883).

• Added from __future__ import unicode_literals to the default apps.py created by startapp on Python 2 (#25909). Add this line to your own apps.py files created using Django 1.9 if you want your migrations to work on both Python 2 and Python 3.

• Prevented QuerySet.delete() from crashing on MySQL when querying across relations (#25882).

• Fixed evaluation of zero-length slices of QuerySet.values() (#25894).

• Correction d’un bogue d’état lors de l’utilisation d’une opération AlterModelManagers (#25852).

• Fixed TypedChoiceField change detection with nullable fields (#25942).

• Fixed incorrect timezone warnings in custom admin templates that don’t have a data-admin-utc-offset attribute in the body tag. (#25845).

• Correction d’une régression qui empêchait l’utilisation d’une langue non présente dans la liste par défaut des langues de Django (LANGUAGES) (#25915).

• Avoided hiding some exceptions, like an invalid INSTALLED_APPS setting, behind AppRegistryNotReady when starting runserver (#25510). This regression appeared in 1.8.5 as a side effect of fixing #24704 and by mistake the fix wasn’t applied to the stable/1.9.x branch.

• Fixed migrate --fake-initial detection of many-to-many tables (#25922).

• Restored the functionality of the admin’s list_editable add and change buttons (#25903).

• Fixed isnull query lookup for ForeignObject (#25972).

• Fixed a regression in the admin which ignored line breaks in read-only fields instead of converting them to <br> (#25465).

• Fixed incorrect object reference in SingleObjectMixin.get_context_object_name() (#26006).

• Made loaddata skip disabling and enabling database constraints when it doesn’t load any fixtures (#23372).

• Restored contrib.auth hashers compatibility with py-bcrypt (#26016).

• Fixed a crash in QuerySet.values()/values_list() after an annotate() and order_by() when values()/values_list() includes a field not in the order_by() (#25316).
