Django provides several decorators that can be applied to views to support various HTTP features.
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.
require_http_methods(request_method_list)[sumber]¶Decorator to require 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
# ...
pass
Catat bahwa cara diminta harus dalam huruf besar.
require_GET()¶Decorator to require that a view only accepts the GET method.
require_POST()¶Decorator to require that a view only accepts the POST method.
require_safe()¶Decorator to require that a view only accepts the GET and HEAD methods. These methods are commonly considered "safe" because they should not have the significance of taking an action other than retrieving the requested resource.
Catatan
Web servers should automatically strip the content of responses to HEAD
requests while leaving the headers unchanged, so you may handle HEAD
requests exactly like GET requests in your views. Since some software,
such as link checkers, rely on HEAD requests, you might prefer
using require_safe instead of require_GET.
The following decorators in django.views.decorators.http can be used to
control caching behavior on particular views.
last_modified(last_modified_func)[sumber]¶These decorators can be used to generate ETag and Last-Modified
headers; see
conditional view processing.
The decorators in django.views.decorators.gzip control content
compression on a per-view basis.
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.
Penghias dalam django.views.decorators.vary dapat digunakan untuk mengendalikan cache berdasarkan pada kepala permintaan khusus.
vary_on_headers(*headers)[sumber]¶Kepala Vary menentukan kepala permintaan mana sebuah mekanisme cache harus diperhitungkan ketika membangun kunci cachenya.
Lihat menggunaan beragam kepala.
Penghias dalam django.views.decorators.cache mengendalikan cache peladen dan sisi-klien.
cache_control(**kwargs)[sumber]¶This decorator patches the response's Cache-Control header by adding
all of the keyword arguments to it. See
patch_cache_control() for the details of the
transformation.
