View decorators

Django provides several decorators that can be applied to views to support various HTTP features.

Allowed HTTP methods

The decorators in django.views.decorators.http can be used to restrict access to views based on the request method. These decorators will return a django.http.HttpResponseNotAllowed if the conditions are not met.


This decorator is used to ensure that a view only accepts particular request methods. Usage:

from django.views.decorators.http import require_http_methods

@require_http_methods(["GET", "POST"])
def my_view(request):
    # I can assume now that only GET or POST requests make it this far
    # ...

Note that request methods should be in uppercase.


Decorator to require that a view only accept the GET method.


Decorator to require that a view only accept the POST method.

Conditional view processing

The following decorators in django.views.decorators.http can be used to control caching behavior on particular views.


These decorators can be used to generate ETag and Last-Modified headers; see conditional view processing.

GZip compression

The decorators in django.views.decorators.gzip control content compression on a per-view basis.


This decorator compresses content if the browser allows gzip compression. It sets the Vary header accordingly, so that caches will base their storage on the Accept-Encoding header.

Vary headers

The decorators in django.views.decorators.vary can be used to control caching based on specific request headers.


The Vary header defines which request headers a cache mechanism should take into account when building its cache key.

See using vary headers.
