Hi! I saw that i documentation here
- http://api.rubyonrails.org/classes/ActiveRecord/Associations/ClassMethods.html
> Overriding generated methods
>
> Association methods are generated in a module that is included into the
> model class, which allows you to easily override with your own methods and
> call the original generated method with super. For example:
>
> class Car < ActiveRecord::Base
> belongs_to :owner
> belongs_to :old_owner
> def owner=(new_owner)
> self.old_owner = self.owner
> super
> endend
>
> 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:
'business_category_id'
def category
super || BusinessCategory.new(name: 'other')
end
end
Why it keeps throwing
super: no superclass method `category' for #<Business:0x000001023014b8>
? Am i missing something?
