STI rails redefine areas

Question

Say I have an STI setup as follows:

class User < ActiveRecord::Base scope :busy, -> { where('busy_factor > 1') } end class HeroUser < User scope :busy, -> { where('busy_factor > 5') } end 

Thus, hero users have a different threshold for employment.

Now, if I do this, I get warnings:

 Creating scope :busy. Overwriting existing method HeroUser.busy. 

Everything seems to work correctly, but I wonder if there is a better way to do this.

Answer 1

Cleaner way:

• Delete region for child models
• Introduce a class method (e.g. busy_factor) that returns a busy factor for this type of model.
• If necessary, override class methods in descendants.

• Repeat the scope in the base class as:

  area: busy, → {where ('busy_factor>?', self.busy_factor)}

Hope this helps.
