Django: “newforms-admin: root() takes exactly 3 arguments (2 given)”

Continued from urls problem.

Regex groups, named groups:

http://www.mail-archive.com/django-users@googlegroups.com/msg54489.html

Yes there is. You can use regex groups:

(r'^admin/(.*)', site1.root),

The string that matches .* will be passed as an extra arg.

Or named groups:

(r'^admin/(?P.*)', site1.root),

Additionaly, you can pass extra args:
