1. $this->Post->id = $id sets the model id field to whatever the id is
that you've passed in the URL. That's retained for the $this->Post-
>read(); underneath it. You can also say things like $this->set
('post', $this->Post->read(null, $id)); to read all the fields for
record $id, for example, instead of assigning the id and then reading
it.2. Every function in the controller IS a method, and every method IS an action ;) They're all synonyms for the same thing. You don't need a view for every controller method, only the ones that you'll logically want a view for, which is what I think you're meaning to ask. 3. $this->data is handled automagically by Cake. It consists of an array of the data that you're moving from one place to another, so you can act on specific fields by calling $this->data['Model']['field']. Hope this helps!
