instance method
inherited
Ruby on Rails 5.0.7.2
Since v4.2.11.3 Private — implementation detail, not part of the public APISignature
inherited(subclass)We need to apply this decorator here, rather than on module inclusion. The closure created by the matcher would otherwise evaluate for ActiveRecord::Base, not the sub class being decorated. As such, changes to lock_optimistically, or locking_column would not be picked up.
Parameters
