How can duplicate the request in django rest framework

Suppose i have this code

class SnippetList(APIView):
    """
    List all snippets, or create a new snippet.
    """
    def get(self, request, format=None):
        snippets = Snippet.objects.all()
        serializer = SnippetSerializer(snippets, many=True)
        return Response(serializer.data)

Now Let us suppose that in my get, i need to modify request.data

    def get(self, request, format=None):
        data = modify(request.data)
        request.data = data    # This don't work as i can't set attribute on request
        response = self.post(self, new_request, format=None)  # i want to do post method now with new request
        serializer = SnippetSerializer(snippets, many=True)

Is there any way to do that

You could try something like this:

def get(self, request, format=None):
        response = self.post(self, request, format=None, data=data )  # i want to do post method now with new request
        serializer = SnippetSerializer(snippets, many=True)

Now your method post should be:

def post(self, request, format=None, **kwargs):
        original_data = request.data
        additional_data = kwargs.get('data') # now you will be able to do whatever you want
        # more code goes here

You should not modify your data upon get as they are usually marked as "unsafe" because they modify the data state.

You don't want to mess with the provided request either. It often creates more issues than it solves and adds some magic.

If you want the serializer to have more data than the request sent you should pass them to the serializer's save function. They will be added to the validated_data and available in the serializer's create / update methods (http://www.django-rest-framework.org/api-guide/serializers/#passing-additional-attributes-to-save)
