Hey Guys,

considering the following Model:

class User \< ActiveRecord::Base  
has\_many :posts, :include =\> [:comments, :ratings], :dependent =\>  
:destroy  
end

This code will raise an ActiveRecord::MissingAttributeError Exception  
(comment\_id is missing):  
@user.post\_ids

Can anyone confirm this or does someone have an idea whats going wrong  
here? Using Rails 2.2.2

Cheers.
