Disable STI

I had to add “self.inheritance_column” as opposed to simply “inheritance_column” to get this to work.

Code example 

class MyModel < ActiveRecord::Base
  # disable STI
  self.inheritance_column = :_type_disabled
end

two ways to disable single table inheritance

  1. Don’t use the column name ‘type’

  2. Or if the first is no option for you: Tell Rails to look for a not existing column like:

class MyModel < ActiveRecord::Base

  # disable STI
  inheritance_column = :_type_disabled
end
