.generate(object) ⇒ Object

Builds a new version for the passed-in object Passed-in object is a dirty object. Version will be saved when the object is saved.

If you must generate a version manually, this method should be used instead of ‘Version.create`. I didn’t want to override the public ActiveRecord API.
