Hey, The @video.id you are referring to is not yet existing as the @video object is not yet persisted into the db. You have to first save the @video before accessing the id, that is when the after_create or after_save is triggered. In your Video class, the after save has access to the @video instance through the self keyword (self.id in your case).
Another solution to your problem would be to use nested attributes (see accepts_nested_attributes_for in the rails docs) I hope this helps.
