thanks all for the detail explanation, learn a lot new things today
{{=DIV(auth.user_groups) }}
*result :*
{1L: 'Admin', 2L: 'User'}
{{=DIV(auth.user_groups.values() ) }}
*result :*
AdminUser
{{=set(auth.user_groups.values() ) }}
*result :*
set(['Admin', 'User'])
now about hitting database, just want to clarify in web2py there is
auth.has_membership()
*e.g.*
*controllers/default.py*
"""
*# 1 usually used*
has_membership_admin = auth.has_membership(role = 'Admin')
"""
*# 2 learn today*
has_membership_admin = 'Admin' in auth.user_groups.values()
def test():
table = db.test
grid = SQLFORM.grid(table, deletable = has_membership_admin)
return locals()
did the #2 is faster than #1 because #2 didn't hit database?
thanks and best regards,
stifan
