Hi all,
I have a problem with coming up with a query for a dropdown list.
I would like a list to only show the options that a user doesn't have.
Scenario,
auth_user 'bill' has auth_membership in 'user1' and 'user3'.
If I want to add another auth_membership to 'bill', I would like only
'user2' and 'user4' options to show up in the dropdown.
I am using SQLFORM.factory for my form
form = SQLFORM.factory(Field('user_id',
requires=IS_IN_DB(db(db.auth_user.id == id), 'auth_user.id',
'%(username)s',zero=None)),
Field('group_id',requires=IS_IN_DB(db(db.auth_membership.user_id ==
id),'auth_group.id','%(role)s')),
submit_button='Add New Membership')
I hope that I am clear with my question.
Thanks in advance
