Represents the encapsulation of all of the details to be included in an update to state machine observers. This allows multiple arguments to get passed to an observer method (instead of just a single object) while still respecting the way in which ActiveModel checks for the object’s list of observers.
The arguments to pass into the method
# File lib/state_machine/integrations/active_model/observer_update.rb, line 24 def args [object, transition] end
The class of the object being transitioned. Normally the object getting passed into observer methods is the actual instance of the ActiveModel class. ActiveModel uses that instance’s class to check for enabled / disabled observers.
Since state_machine is passing an ObserverUpdate instance into observer methods, class needs to be overridden so that ActiveModel can still get access to the enabled / disabled observers.
# File lib/state_machine/integrations/active_model/observer_update.rb, line 36 def class object.class end
