 def process_request(self, request):
 """ Reads url name, args, kwargs from GET parameters, reverses the url and resolves view function Returns the result of resolved view function, called with provided args and kwargs Since the view function is called directly, it isn't ran through middlewares, so the middlewares must be added manually The final result is exactly the same as if the request was for the resolved view. Parametrized urls: djangoUrl.reverse can be used with parametrized urls of $resource In that case the reverse url is something like: /angular/reverse/?djng_url_name=orders&djng_url_kwarg_id=:id $resource can either replace the ':id' part with say 2 and we can proceed as usual, reverse with reverse('orders', kwargs={'id': 2}). If it's not replaced we want to reverse to url we get a request to url '/angular/reverse/?djng_url_name=orders&djng_url_kwarg_id=' which gives a request.GET QueryDict {u'djng_url_name': [u'orders'], u'djng_url_kwarg_id': [u'']} In that case we want to ignore the id param and only reverse to url with name 'orders' and no params. So we ignore args and kwargs that are empty strings. """
