corrected documentation for {% url %} resolver

[V]

there were two errors:

1. ('^client/(\d+)/$', 'app_name.app_views.client') originally ('^client/(\d+)/$', 'app_views.client')

gives you an ImportError (ViewDoesNotExist)

2. {% url app_name.app_views.client client.id %} originally {% url app_views.client client.id %}

simply doesn't work

to check I did:

1. startapp app_name
2. add urls.py to the main urls.py as in the docs
3. add urls.py to app_name/urls.py as shown above
4. creates app_views.py with view client that gives back {% url app_views.client client.id %}
