Hi! I saw that i documentation here
self.old_owner = self.owner super
If your model class is Project, the module is named
Project::GeneratedFeatureMethods. The GeneratedFeatureMethods module is
included in the model class immediately after the (anonymous) generated
attributes methods module, meaning an association will override the methods
for an attribute with the same name.
Now this is my model
class Business < ActiveRecord::Base
belongs_to :category, class_name: ‘BusinessCategory’, foreign_key:
super || BusinessCategory.new(name: ‘other’)
Why it keeps throwing
super: no superclass method `category’ for #Business:0x000001023014b8
? Am i missing something?
