Re: Observer Pattern in CakePHP 2.0

I thing the example in article 2 is great but i don't think is necessary to create a component to register observers.

Observer pattern need two part, Subject and Observer, so i think you need another observer behavior ( not only observable behavior ).

Observer pattern is usually implemented by interface, cakephp's behavior can do the same.

Hi All:

I would like to implement observer pattern [1] in my project and would like to hear your suggestions regarding cake's way of doing it the right way. Most web searches led me to an article [2] written in 2009. I am sure a lot of things have changed since then :)

In my project (which tracks movement of domain names and ipaddresses), I am looking to implement observer pattern where whenever the subject (e.g. domain name) changes (e.g. moves to a new ipaddress), it triggers multiple observers such as reputation, blacklisted, whitelisted, ranking, geo-location, etc...

Thanks in Advance,
