After some research it seems that's not the cause of the problem. I created a blank project, removed all plugins and the error persisted:
> User.last.conversations.find(Conversation.last.id).users.last.instance_of?(User) => true > reload! Reloading... => true > User.last.conversations.find(Conversation.last.id).users.last.instance_of?(User) => false I removed this line I had in the Conversation model: default_scope :order => 'updated_at desc' Now the models are exactly as shown in my first post, and now there's no class bug. Of course, I have been testing with only one user, one conversation and one reading (otherwise the order in the default scope would make a big change in the query). -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
