Error: The response content must be rendered before it can be accessed.

[sonu kumar]

class based views are as below

class TagList(TemplateView):

     def get_context_data(self, **kwargs):

         ...

         qlist = QueList.as_view()(self.request, **kwargs)
         print qlist

         ...
        

class QueListView(ListView):
    def get_context_data(self, **kwargs):
        ...

When QuesList.as_view() is called then it produces The response content must be rendered before it can be accessed . on print qlist line How to fix this error and what's reason behind this?

     

[Daniel Roseman]

Because a TemplateView returns a TemplateResponse, which needs to be rendered. See the docs: https://docs.djangoproject.com/en/1.8/ref/template-response/

Can you explain why you are doing this? What's the point of calling one view from another? There's almost certainly a better way to achieve what you want.

I am having different URLs configuration. same view is called for two URLs based on **kwargs decision is made what to do? In one of case I need to get result of all related objects which is tagged with given keyword. I found another way to do achieve same using function based view.
