Defines the column name for use with single table inheritance. Use set_inheritance_column to set a different value.

      def inheritance_column
        @inheritance_column ||= "type"
      end

Don't use the column name 'type'
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

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
