Overriding association getters

Hi! I saw that i documentation here

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?

Possibly because AR::Base has no idea about your renaming of that
association. Try calling that method business_category instead, or call
business_category instead of super. (Just don’t do both,)

Hey, but i did not rename it. My model hasn’t methods called
busyness_category! I though AR generates them according to first
argument
to ‘belongs_to’ method, rather than from foreign key name

Weird - I created a fresh rails app, added a business model like yours
and
it works fine. I’d recommended doing the same and seeing whether you can
isolate what it is about your app that is different (for example is
Business::GeneratedAssociationMethods in the ancestor chain for
business?
What does Profile::GeneratedAssociationMethods.instance_methods look
like?)

Which version of rails?

Oh yeah, this is because of one gem i use that extends AR in that way.
Thanks that you set up fresh app, that helped me.
