Hi,
in my model I have users who have membership to more groups.
I am trying to perform a query of users who DO NOT belong to a group; 
something along these lines:

query = db ((db.auth_user != auth.user.id) & (~(auth.has_membership 
("admin", db.auth_user.id))).select (db.auth_user.first_name, 
db.auth_user.last_name)

The above query does not work, i.e. it retrieves all records except the 
currently logged in user (which is OK) but ignores the "has_membership" 
condition. It gives no errors, though...

I know I can perform the select with only the first condition and then loop 
over the result to remove the users that have membership to group "admin", 
but I wonder if I can have the result in a single query.

Thanks!
