Getting Distinct Rows While Still Returning Other Fields

On occasion I encounter this problem but I never remember how I fix it
the time before... which is annoying for myself.

I have the following find:
@conversations = Message.find(:all, :select => "DISTINCT from_user_id,
created_at", :conditions => ["to_user_id = ?", session[:user_id]])

I want distinct from_user_id but at the same time I want to have other
fields removed like created_at. If I return more then from _user_id I
am not getting distinct from_user_ids...

What is the rails way of solving my problem? :slight_smile:

Thanks eveyone for helping me out! :slight_smile:
