I'm still learning web2py, I'm working on access control and was confused by a few things I was hoping to understand better.
1 - Why is auth_user in db.py, but none of the other auth_ tables are? 2 - If I wanted to add or modify any of the auth tables, how would I do that? auth_user is in db.py but the other auth_ tables aren't. Previously when I tried to define a auth_group or similar access control table I got all sorts of errors but I can't find anywhere else to modify them. 3- Are there any plugin's or appliances for web2py with a admin already done for user/group management? Thanks,
