View decorators
|
|
===============
|
|
|
|
.. currentmodule:: django.views.decorators.http
|
|
|
|
Django provides several decorators that can be applied to views to support
|
|
various HTTP features.
|
|
|
|
Allowed HTTP methods
|
|
====================
|
|
|
|
.. function:: require_http_methods(request_method_list)
|
|
|
|
This decorator is used to make a view only accept 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
|
|
# ...
|
|
pass
|
|
|
|
Note that request methods should be in uppercase.
|
|
|
|
.. function:: require_GET()
|
|
|
|
Decorator to require that a view only accept the GET method.
|
|
|
|
.. function:: require_POST()
|
|
|
|
Decorator to require that a view only accept the POST method.
|
|
|
|
Conditional view processing
|
|
===========================
|
|
|
|
.. function:: condition(etag_func=None, last_modified_func=None)
|
|
|
|
.. function:: etag(etag_func)
|
|
|
|
.. function:: last_modified(last_modified_func)
|
|
|
|
These decorators can be used to generate ``ETag`` and ``Last-Modified``
|
|
headers; see
|
|
:doc:`conditional view processing </topics/conditional-view-processing>`.
|
|
|
|
.. currentmodule:: django.views.decorators.gzip
|
|
|
|
GZip compression
|
|
================
|
|
|
|
.. function:: gzip_page()
|
|
|
|
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.
|
|
|
|
.. currentmodule:: django.views.decorators.vary
|
|
|
|
Vary headers
|
|
============
|
|
|
|
The ``Vary`` header defines which request headers a cache mechanism should take
|
|
into account when building its cache key.
|
|
|
|
.. function:: vary_on_cookie(func)
|
|
|
|
.. function:: vary_on_headers(*headers)
|
|
|
|
See :ref:`using vary headers <using-vary-headers>`.
