Rake tasks use class methods, migrations use instance methods. To avoid repetition a lot of instance methods here just call class methods. The subclass Card::CoreMigration needs a different @type so we can’t use a class variable @@type. It has to be a class instance variable. Migrations are subclasses of Cardio::Migration or Card::CoreMigration but they don’t inherit the @type. The method below solves this problem.
