As he did once before, tobius inspired me to write some code again. This time he was trying to make scaffolding more individual, so the first thing I pointed out to him was my blog post about using generateFields for using some of the scaffolding powers. Now one problem remained: He wanted to use the same views over and over again so I had an idea about how to reuse views in a simple and efficient manner.

Here is what I did:

app/app_controller.php

/* This is our AppController that will help us to use 4 common CRUD views */
class AppController extends Controller
{
function render($action=null, $layout=null, $file=null)
{
if (!isset($action) && in_array($this->action, array('create', 'update', 'read', 'delete')))
{
parent::render('../crud/'.$this->action, $layout, $file);
}
else
{
parent::render($action, $layout, $file);
}
}
}

app/items/items_controller.php

/*
This is a sample items controller with basic CRUD functions
*/
class ItemsController extends AppController
{
var $uses = array(); // This test controller doesn't use db

function create()
{
// This will use app/views/items/create.thtml
$this->render('create');
}

function read()
{
// This will use app/views/crud/read.thtml
}

function update()
{
// This will use app/views/crud/update.thtml
}

function delete()
{
// This will use app/views/crud/delete.thtml
}

}

I hope it's useful to somebody out there ; ).
