eager loading has_many through

hi all,

My relationships:
- group habtm user and
- user has_many events :through statistics.
The statistics contains the id of user and is of event and additional

How can I get all the users in a group with their statistics via eager

I tried:
@users = a_node.users.find(:all, :include => :statistics, :conditions
=> ["statistics.event_id = ?", event.id])

The problem is that I only get the users with a statistics record and
I also want users without any stastics. I think the problem is caused
by :conditions => ["statistics.event_id = ?", event.id] but I don't
know how to include the event_id in another way.

Someone can help me out?


:include => [:statistics, :events] or :include => “:statistics, :events”
