Is there a better way of writing this code? It just doesn't sit right with me, I feel like there is something really 'rails like' that I should already know: belongs_to :parent_in_use belongs_to :parent_template def after_create new_parent_in_use = ParentInUse.create!(self.parent_template.attributes) self.update_attribute(:parent_i...

I have a tickets table that has two columns (submitter_id and assignee_id) that should each reference a different user from the users table (specifically the id column in the users table). I'd like to be able to do things...
