How to programmatically call a Django Rest Framewo

问题:

I have the following generic class based views built with Django Rest framework (DRF)

class ExampleDetail(generics.RetrieveUpdateDestroyAPIView):
    queryset = Example.objects.all()
    serializer_class = ExampleSerializer
    renderer_classes = (JSONRenderer, TemplateHTMLRenderer)

    def get(self, request, *args, **kwargs):

        response = self.retrieve(request, *args, **kwargs)
        if request.accepted_renderer.format == 'html':
            form = ExampleForm(data=response.data)
            return Response({'data': response.data, 'form': form}, template_name='example.html')

        return response

This view allow me to obtain both JSON data or HTML form from the same endpoint by specifying the format=json or html.

I would like to programmatically call that view to obtain the rendered HTML form from within another view in order to include this form in another page that will include more stuff.

I found the solution for this in the documentation... https://docs.djangoproject.com/en/1.7/topics/class-based-views/mixins/

Hint is from their example here:

class AuthorDetail(View):

    def get(self, request, *args, **kwargs):
        view = AuthorDisplay.as_view()
        return view(request, *args, **kwargs)

    def post(self, request, *args, **kwargs):
        view = AuthorInterest.as_view()
        return view(request, *args, **kwargs)

回答2:

html_from_view = ExampleDetail.as_view({'get': 'list'})(request).content

OR

html_from_view = ExampleDetail.as_view({'get': 'retrieve'})(request, pk=my_id).render().content

If I'm understanding correctly, you need to get the result from view B, while inside view A.

Using the requests/urllib2 and json libraries should solve your problem (as specified in this answer).

To get the URL, you can use a combination of request.get_absolute_uri() and/or request.get_host() and django.core.urlresolvers.reverse.
