Inheriting from an Abstract Class

Joshua Pinter edited this page Feb 9, 2015 · 2 revisions

If you have an abstract base class that other classes inherit from, you cannot add acts_as_paranoid on the Abstract Class, otherwise you will get an empty table name in the query:

class BaseClass < ActiveRecord::Base
  self.abstract_class = true
  
  acts_as_paranoid
end

class InheritedClass < BaseClass
end

>> InheritedClass.scoped.where_sql
# => "WHERE (``.deleted_at IS NULL)"

You have to put the acts_as_paranoid on the InheritedClass for it to use the correct table name in the scope.
