You know, I think I have to check current user in the model callbacks (like before_update). Rather than rely solely on adding where ('something.user_id = ?', 'current_user.id') in the controllers. I need something like Thread.CurrentPrincipal in .NET
Is it safe to put reference to current user in User model? I'm sorry I don't really understand how it works under the hood yet.
Or how you do it The Rails way?
Sorry if this a silly question.
