rails latest stable - Class: ActiveRecord::Persistence

becomes!(klass)

public

Wrapper around #becomes that also changes the instance’s STI column value. This is especially useful if you want to persist the changed class in your database.

Note: The old instance’s STI column value will be changed too, as both objects share the same set of attributes.
