Hi All
Someone please point me in the right direction with this.
I would like to implement an event / listener pattern in parts of my
application. But I don't quite like the Observer pattern as it is as it
hides the flow, I will like something explicit, where you trigger events
manually. See made up code below:
class User < ActiveRecord::Base
def something
trigger :on_something, name
end
end
class UserObserver < ActiveRecord::Observer
def on_something(name)
...
end
end
I have been looking at
custom callbacks
http://api.rubyonrails.org/classes/ActiveSupport/Callbacks/ClassMethods.html#method-i-define_callbacks
Observers
http://api.rubyonrails.org/classes/ActiveRecord/Observer.html
But nothing quite does what I want, or I don't know how to hook it
together. Any suggestions / gems on this will be appreciated.
Thanks,
Sebastian
