Django - 基于类的视图的URL缓存失败 [英] Django--URL Caching Failing for Class Based Views

问题描述

我已经在Django Rest框架之上构建了一个RESTful API。 API的URL conf由基于类的视图组成。

我想缓存这些视图，但是，以下是失败。任何关于为什么可能会改变它的想法？

  from django.views.decorators.cache import cache_page 
 
 urlpatterns = patterns（''，
 url（r'^ dounces /？$'，cache_page（60 * 60）（DounceListView.as_view（resource = DounceResource）），name ='dounces_api' ）
  

我安装了以下中间件。

 'django.middleware.gzip.GZipMiddleware'，
'django.middleware.common.CommonMiddleware'，
'django.contrib.sessions.middleware.SessionMiddleware '，
'django.contrib.auth.middleware.AuthenticationMiddleware'，
'django.contrib.messages.middleware.MessageMiddleware'，
'django.middleware.transaction.TransactionMiddleware'，
'django.contrib.redirects.middleware.RedirectFallbackMiddleware'，
  

为了本地测试， m使用默认缓存后端：

 'BACKEND'：'d jango.core.cache.backends.locmem.LocMemCache'，
  

解决方案

p>将您的urlconf更改为

  urlpatterns = patterns（''，
 url（r'^ dounces /？$ '，cache_page（60 * 60）（DounceListView.as_view（resource = DounceResource）），name ='dounces_api'），
）

I've built a RESTful API on top of the Django Rest Framework. The URL conf for the API is composed of class based views.

I would like to cache these views, however, the following is failing. Any thoughts on why that might be and how I could change it?

   from django.views.decorators.cache import cache_page

   urlpatterns = patterns('',
   url(r'^dounces/?$', cache_page(60*60)(DounceListView.as_view(resource=DounceResource)), name='dounces_api'),

I have the following middleware installed.

'django.middleware.gzip.GZipMiddleware',
'django.middleware.common.CommonMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.transaction.TransactionMiddleware',
'django.contrib.redirects.middleware.RedirectFallbackMiddleware',

AND for local testing, i'm using the default caching backend:

 'BACKEND': 'django.core.cache.backends.locmem.LocMemCache',

解决方案

change your urlconf to

urlpatterns = patterns('',
    url(r'^dounces/?$', cache_page(60*60)(DounceListView.as_view(resource=DounceResource)), name='dounces_api'),
)
