Hi I have an infuriating problem.

I have a url pattern like this:

```
# mproject/myapp.urls.py

url(r'^project/(?P<project_id>\d+)/$','user_profile.views.EditProject',name='edit_project'),

```

it works fine in the browser but for testing, when I do this in the shell:

```
from django.test import Client
from django.core.urlresolvers import reverse

client= Client()
response = client.get(reverse('edit_project'), project_id=4)

```

I get the dreaded:

```
NoReverseMatch: Reverse for 'edit_project' with arguments '()' and keyword arguments '{}' not found.

```

What am I missing here?
