my error is similar to django's error : __init __ () takes exactly 1 argument (2 given) , but since there is no right answer, and I can not find a way to solve this now. So, I ask again.
In views.py I write:
class JSONResponse(HttpResponse): """ An HttpResponse that renders its content into JSON. """ def __init__(self, data, **kwargs): content = JSONRenderer().render(data) kwargs['content_type'] = 'application/json' super(JSONResponse, self).__init__(content, **kwargs) class SnippetListView(APIView): queryset = Snippet.objects.all() def get(self, request, format=None): users = self.queryset serializer = SnippetSerializer(users, many=True) return Response(serializer.data) def post(self, request, format=None): serializer = SnippetSerializer(data=request.DATA) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) else: return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
In urls.py I write:
from django.conf.urls import patterns, url from rest_framework.urlpatterns import format_suffix_patterns from snippets.views import * urlpatterns = patterns('snippets.views', url(r'^snippets/$', SnippetListView.as_view()), url(r'^snippets/(?P<pk>[0-9]+)/$', 'snippets.views.SnippetDetailView'), )
And then I run python manage.py runningerver and it shows me the error message: ImportError at / snippets /
No module named snippets
but i am importing fragments in settings.py
INSTALLED_APPS = ( 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'django.contrib.messages', 'django.contrib.staticfiles', 'rest_framework', 'snippets', )
