I have an email subscription form on my website that visitors can fill
out and subscribe to our newsletter. I have created a
subscriberBean.cfc with getters/setters and an email validation
method, a subscriberDAO.cfc with CRUD methods, and a service that
creates a DAO object and a gateway object and passes arguments to the
DAO and the gateway (this is all based on Matt Woodwards
CF.Objective() example and Peter Farrell's code examples from CFWeekly
1.10).
It seems to me like the view would interact with the service, which
would perform my CRUD operations and return my the query results from
my gateway. If so, what do I need a controller for? I've heard that
controllers act as traffic cops, but I'm not sure what that means. If
my view is validating form field entries, and my model is validating
form field entries, and my view is getting everything it needs from
the service layer, what do I need a "traffic cop" for?
Thanks for your feedback and suggestions!
