v5.1.7 - Show latest stable - Class: ActiveRecord::Locking::Optimistic::ClassMethods

inherited(subclass)

private

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.

              subclass.class_eval do
                is_lock_column = ->(name, _) { lock_optimistically && name == locking_column }
                decorate_matching_attribute_types(is_lock_column, :_optimistic_locking) do |type|
                  LockingType.new(type)
                end
              end
              super
