Rails3 newbie - Question regarding multiple joins and finder methods

Hello all

I've encountered a weird difficulty...I wonder what am I doing wrong..

I have three models: User,Assignment,Idea The User has many assignments and each assignments belongs to Idea. I have also defined has many through relations on User (ideas) and on Idea (users) -- through assignments...

The database is populated with the needed data..

I am using this to query the models.. @out = User.joins(:ideas,:assignments => [:user,:idea]).includes(:ideas,:assignments => [:user,:idea]).find(1)

The result contains a User object with ideas array (has_many) with one Idea object but its empty (all attributes are nil)... It also contains an assignments array (has_many) with one Assignment object but the reference to the Idea (belongs_to) is null.. (user_id,idea_id do exist and have correct value) It is like the join is not performed..

BTW- The console shows that the JOIN is performed.

What is wrong?

Thanks in advance Afik
