I'm learning DRF and feel confused a little now.
I set up QuestionView
and QuestionSerializer
like this.
views.py
class QuestionView(viewsets.ModelViewSet) :
queryset = models.Question.objects.all()
serializer_class = QuestionSerializer
def list(self, request, *args, **kwargs):
serializer = QuestionSerializer(models.Question.objects.all())
return Response(serializer.data)
serializer.py
class QuestionSerializer(serializers.ModelSerializer):
class Meta:
model= Question
fields= ("question_text", "owner", "pub_date")
urls.py
router = routers.DefaultRouter()
router.register('profile', cebula_views.SettingView)
router.register('question', cebula_views.QuestionView.as_view({
'get':'list',
}), 'userpage-question')
urlpatterns = [
...
url(r'^', include(router.urls)),
...
]
File "C:\Users\1Sun\Cebula3\businessproject\urls.py", line 34, in url(r'^', include(router.urls)), File "C:\Users\1Sun\AppData\Local\Programs\Python\Python36\lib\site-packages\rest_framework\routers.py", line 101, in urls self._urls = self.get_urls() File "C:\Users\1Sun\AppData\Local\Programs\Python\Python36\lib\site-packages\rest_framework\routers.py", line 363, in get_urls urls = super(DefaultRouter, self).get_urls() File "C:\Users\1Sun\AppData\Local\Programs\Python\Python36\lib\site-packages\rest_framework\routers.py", line 261, in get_urls routes = self.get_routes(viewset) File "C:\Users\1Sun\AppData\Local\Programs\Python\Python36\lib\site-packages\rest_framework\routers.py", line 176, in get_routes extra_actions = viewset.get_extra_actions() AttributeError: 'function' object has no attribute 'get_extra_actions'
In my opinion, It is that I should write get_extra_actions
method in QuestionView
class, If so, how I write that? like this?
def get_extra_actions() :
return ???
If not, what is the problem?
[Edit]
when I erase .as_view() at the url part and write like router.register('question', cebula_views.QuestionView, 'userpage-question')
the error is
