This is IMHO a total mix up of terms. Yes, MVC preaches that view and business logic shall be separated for all eternity. But what Craig was saying is totally valid. You should be able to call methods on your model. MVC says the business logic should be in the model. Exactly!
He only wants to CALL the methods from the view, which is perfectly fine. This does not contradict MVC in any way. In Ruby on Rails you can do this. The reason this doesn't work in Cake PHP is simply one of it's shortcomings. The ActiveRecord pattern is not done 'correctly' (i.e. not all aspects are implemented). A row should correspond to an object. ( http://en.wikipedia.org/wiki/Active_record_pattern ) So Craig, yes you should be able to do this but its not possible in cake PHP. Coming from the Java world you might want to check out Ruby on Rails, to not make your head hurt so much when you come across PHP's limited ability of OO.
