I'm assuming that 'instance_id' is an attribute of a Book. In that case, it needs to be part of the Hash you pass to #build or #create. You can do either: > params[:book][:instance_id] = current_user.instance_id > @book = current_user.books.create(params[:book]) or > @book = current_user.books.create(params[:book].merge(:instance_id => current_user.instance_id)) Both assume that params[:book] is non-nil and is a Hash. I'd prefer the first - it's more readable. Adam -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
