ContentNotRenderedError while using django middleware

Question

I used process_request and process_response functions in django middleware in order to log the requests before hitting the viewset. But, I get Internal Server Error. I don\'t

Answer 1

The problem is the return Response() in your middleware methods.

If you return a response in the process_request method, then Django will not call the view. You probably don't want to return anything here.

You should return a response from the process_response method. You probably want to return the original response from the view (response) here. If you return a different response (e.g. Response(...)), then Django will return this to the user instead of the response from the view.

class MyMiddleware(): 
    def process_request(self, request): 
        print "xxxxx"

    def process_response(self, request, response): 
        print "xxxxx"
        return response

See the Django docs for more information about what you should return from each middleware method.

Answer 2

I fixed the issue. It's because the response object returned by process_response doesn't have actual response. I modified it to following and it worked.

class MyMiddleware(): 
    def process_request( self, request ): 
        print "xxxxx"
        return None
    def process_response( self, request, response ): 
        print "xxxxx" 
        return response
