title: Django Piston issue - "oauth_user_auth() takes exactly 1 argument (2 given)"
body: <p>I am having a few problems setting up Django Piston. I have managed to get as far as generating authentication via the oauth_client.py sample shown here (<a href="http://github.com/clemesha/django-piston-oauth-example" rel="nofollow noreferrer">http://github.com/clemesha/django-piston-oauth-example</a>). When I run "python oauth_client.py" i am taken to <a href="http://localhost:8000/api/oauth/authorize/?oauth_token=8wm33jeWR92BpsrHjs" rel="nofollow noreferrer">http://localhost:8000/api/oauth/authorize/?oauth_token=8wm33jeWR92BpsrHjs</a> where I then tick a box to confirm access and then submit the form.</p>
  
  <p>At this point i hit a "oauth_user_auth() takes exactly 1 argument (2 given)" error. Simple answer, i'm sure, is that the oauth_user_auth method doesnt accept one parameter, but to remove that character i would have to edit a piston file, which i'm a little reticent to do so. Has anyone else come across this issue before?</p>
