问题 I have 3 models with a has_many through relationship: Food (eg: Chocolate), Sub (Chocolate food substitute), Joint (joint table). Say @food = Food.find(1); The has_many through relationship allows me to do @subs = @food.subs which return all substitutes associated with @food. This work fine, however only the Sub id is saved and not its attributes which are :name and :description as you can see it returned nil when trying to save @food.subs in my create action in my controller: => #

问题 Quick problem description The value of the id in a nested form is rendered as 10006.0 instead of 10006 (decimal/float instead of an integer) resulting in an ActiveRecord::RecordNotFound exception.
