Constructor Details

#initialize(controller, target = nil) ⇒ Object

This class is for internal usage. No need to initialize this manually, instead use controller methods provided.

When being used as automatical way in controller, e.g. as after_filter, supply the controller

ActivityProcessor.new(self)

If cache options needs to be attached, ensure the second argument

ActivityProcessor.new(self, nil, foo: 'bar')

When being used manually, normally the target would be provided

ActivityProcessor.new(self, @article, foo: 'bar')

Parameters:

  • controller (Object) —

    The controller object, often self in controller

  • target (Object) (defaults to: nil) —

    The target instance. If nil, it will be found based on controller.

    When supplied manually, target should be free of error, aka, after controller actiton(create, update etc) success

  • reference (Hash) —

    When required, the second arg “target” should be there, either object or nil

Instance Method Details

#save ⇒ Object

Return nil at this level, but not at #initialize. The reason is not to throw error on ‘nil.create_activity`, for validation error of target is common case. SimpleActivity should let it pass.
