[web2py] Hide tables to appadmin based on user permissions

[Thadeus Burgess]

I would like to hide all tables except the selected one from a user
unless they have specific privileges.

I am thinking maybe the following at the top of appadmin.py

if auth.has_permission('Operations', auth.user.id):
   tables = [copy.copy(t) for t in db]
   db = DAL(db._connection)
   for t in tables: db.define_table(t)

Would this approach work and be appropriate?
