【问题描述】：
我正在尝试使用 Django Rest Framework 为我的活动计划应用程序编写一个 RESTful API，但是在使用不期望 GET HTTP 方法的视图时遇到了一些问题。我已经阅读了 DRF 网站上的教程。根据我在阅读教程和 Django 站点上基于类的视图文档后的理解，如果有这样的基于类的视图（取自 DRF 教程）
class SnippetDetail(APIView):
"""
Retrieve, update or delete a snippet instance.
"""
def get_object(self, pk):
try:
return Snippet.objects.get(pk=pk)
except Snippet.DoesNotExist:
raise Http404
def get(self, request, pk, format=None):
snippet = self.get_object(pk)
serializer = SnippetSerializer(snippet)
return Response(serializer.data)
def put(self, request, pk, format=None):
snippet = self.get_object(pk)
serializer = SnippetSerializer(snippet, data=request.DATA)
if serializer.is_valid():
serializer.save()
return Response(serializer.data)
return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
def delete(self, request, pk, format=None):
snippet = self.get_object(pk)
snippet.delete()
return Response(status=status.HTTP_204_NO_CONTENT)
视图中不同的方法对应不同的HTTP Request方法。因此，如果我有www.foo.com/bar，它将根据发送到该地址的请求方法做两件不同的事情。所以这意味着我不必指定任何其他内容，因为执行的函数是根据发送 URL 的方法确定的。这是正确的吗？
我有这个视图，我试图模仿 DRF 网站上的示例
class EventDetail(APIView):
"""
Retrieve, update or delete a event instance.
"""
def get_object(self, pk):
try:
return Event.objects.get(pk=pk)
except Event.DoesNotExist:
raise Http404
def get(self, request, pk, format=None):
event = self.get_object(pk)
serializer = EventSerializer(event)
return Response(serializer.data)
def post(self, request, format=None):
serializer = EventSerializer(data=request.DATA)
if serializer.is_valid():
serializer.save()
return Response(serializer.data, status=status.HTTP_201_CREATED)
return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
# def put(self, request, pk, format=None):
# event = self.get_object(pk)
# serializer = EventSerializer(event, data=request.DATA)
# if serializer.is_valid():
# serializer.save()
# return Response(serializer.data)
# return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
def delete(self, request, pk, format=None):
event = self.get_object(pk)
event.delete()
return Response(status=status.HTTP_204_NO_CONTENT
映射到这些 URL
urlpatterns = patterns('',
# Get event
url(r'^(?P<pk>\d+)/$', views.EventDetail.as_view(),
name='create_events'),
# list all events
url(r'^list/$', views.EventList.as_view(),
name='list_events'),
# url(r'^update$/(?P<pk>\d+)', #update event),
url(r'^create/$', views.EventDetail.as_view(),
name='create_events'),
# delete event
url(r'^delete$/(?P<pk>\d+)',
views.EventDetail.as_view(), name='delete_event'),
)
我正在尝试使用带有此命令的 CURL 进行测试（如此处建议的 DELETE using CURL with encoded URL）
curl -X DELETE "http://127.0.0.1:8000/events/delete/1"
这似乎会做它应该做的：
[18/Oct/2014 22:41:27] "DELETE /events/delete/1 HTTP/1.1" 404 2707
但实际记录并没有从我的数据库中删除
这里有什么我忘记做的事情来让它们正常工作吗？
