Hi,
I have a HABTM data model with two tables: Users and Groups I have a join table: groups_users.
I am given a set of group_ids.
The SQL that I would like to see generated would read something like this:
select distinct id from users join groups_users on users.id=groups_users.user_id where group_id in (1,2,3);
How do I construct a find, such that I select the unique user ids belonging to the set of group_ids? Is this possible using ActiveRecord associations?
Thanks!
David
