View name is not available from request.resolver_match about django-prometheus

[korfuri]

https://github.com/korfuri/django-prometheus/blob/master/django_prometheus/middleware.py#L120 occurs in process_view which is run after the resolver_match is set (because URL processing needs to happen before view processing). We have a test covering this metric at https://github.com/korfuri/django-prometheus/blob/master/tests/end2end/testapp/test_middleware.py#L38.

If you are running a system where this metric is never incremented, please reopen and let me know about your setup. Thanks a lot!

HI, thank you for getting back to me. We are using gevent and gevent.WSGIServer with Django 1.4.18. When I add the following line in a middleware.process_view method:

class ProfilerMiddleware(object):

    def process_view(self, request, view_func, view_args, view_kwargs):
        print "************", request.resolver_match.view_name
        ...

I see the following output:

Traceback (most recent call last):
  File "/home/jtallieu/.een/gateway/lib/python2.7/site-packages/django/core/handlers/base.py", line 103, in get_response
    response = middleware_method(request, callback, callback_args, callback_kwargs)
  File "/home/jtallieu/.een/gateway/lib/python2.7/site-packages/videobank/core/profiler.py", line 52, in process_view
    print "************", request.resolver_match.view_name
AttributeError: 'WSGIRequest' object has no attribute 'resolver_match'

This appears to depend on the version of Django in use. Can you try with a supported Django version? 1.4 is quite old and was EOL'd in October 2015. The next version of django-prometheus will drop support for Django versions < 1.8.
