How to jump last visited url in Django? (Django cannot provide build-in method and the request.META.REFERER can't work in all scenarios), so write a custom middleware is necessary.

custom_middlewares.py

#it is in the backend package
class PreviousURLMiddleware(object):
    def process_response(self, request, response):
        if response.status_code == 200:
            try:
                request.session["previous_url"] = request.session["current_visiting"]
            except:
                pass
            request.session["current_visiting"] = request.get_full_path()
        return response

settings.py

INSTALLED_APPS += ('backend')
