Method deprecated or moved

This method is deprecated or moved on the latest stable version. The last existing version (v3.1.0) is shown here.

These similar methods exist in v4.2.1:

ensure_proper_type() private

Sets the attribute used for single table inheritance to this class name if this is not the ActiveRecord::Base descendant. Considering the hierarchy Reply < Message < ActiveRecord::Base, this makes it possible to do Reply.new without having to set Reply = "Reply" yourself. No such attribute would be set for objects of the Message class in that example.
