Rails — use type column without STI?

Question

I want to use a column called type without invoking Single Table Inheritance (STI) - I just want type to be a normal column that holds a Stri

Answer 1

Rails 4.x

I encountered the problem in a Rails 4 app, but in Rails 4 the set_inheritance_column method does not exist at all so you can't use it.

The solution that worked for me was to disable the single table inheritance by overriding ActiveRecord’s inheritance_column method, like this:

class MyModel < ActiveRecord::Base

  private

  def self.inheritance_column
    nil
  end

end

Hope it helps!
