I am trying to write an RESTful API for my event planning app using Django Rest Framework but I am having some trouble when using views that do not expect the GET HTTP method. I have read through the tutorial on the DRF site. From what I understand after reading through the tutorial and the class based view documentation on the Django site is that if there is a class based view like this (taken from the DRF tutorial)
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)
The different methods in the view correspond to the different HTTP Request methods. So if I have www.foo.com/bar it would do two different things based on what request method is sent to that address. So that means that I wouldn't have to specify anything else because the function that is executed is determined based on the method the URL is sent with. Is this correct?
I have this view which I tried to model after the example on the DRF site
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
which maps to these URLs
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'),
)
which I am trying to test using CURL with this command (like suggested here DELETE using CURL with encoded URL)
curl -X DELETE "http://127.0.0.1:8000/events/delete/1"
This will seem to do what it should:
[18/Oct/2014 22:41:27] "DELETE /events/delete/1 HTTP/1.1" 404 2707
But the actual record is not deleted from my database
Is there something here that I am forgetting to do to get these to get this to work properly?
