PostgreSQL, Rails and :order => problem

Question

I have the following line in my ActiveRecord model:

class Record < ActiveRecord::Base
    has_many :users, :through => :record_users, :uniq => true,         


        

Answer 1

I suppose you could call it a bug in ActiveRecord. PosgreSQL is a bit more restrictive than MySQL. You can help out ActiveRecord by setting up the association like this instead:

class Record < ActiveRecord::Base
  has_many :users,
   :through => :record_users,
   :select => 'DISTINCT users.*, record_users.index',
   :order => "record_users.index ASC"
