ORM.observers.enable :user_observer
# => enables the UserObserver
User.observers.enable AuditTrail
# => enables the AuditTrail observer for User notifications.
# Other models will not be affected (i.e. they will not
# trigger notifications to AuditTrail if previously disabled)
ORM.observers.enable :observer_1, :observer_2
# => enables Observer1 and Observer2 for all models.
ORM.observers.enable :all
# => enables all observers for all models.
User.observers.enable :all do
# all user observers are enabled for
# just the duration of the block
end
Note: all observers are enabled by default. This method is only useful when you have previously disabled one or more observers.
