In an attempt to keep my scripts maintainable, I'm going to move each into their own file, organised by controller and action:
// scripts which only apply to /views/posts/add.ctp
/app/webroot/js/page/posts/add.js
// scripts which only apply to /view/users/index.ctp
/app/webroot/js/page/users/index.js
That's all cool, however I'd like for these to be automatically added by the Controller, since it obviously knows the name of both the controller and action.
I figure the best place for this is in AppController::beforeRender(). (yes?)
The only problem is that I don't know how to actually add this into the $scripts_for_layout variable. I thought that getting a reference to the javascript helper object would work, but I can't find it from the controller!
class AppController extends Controller {
var $helpers = array("javascript", "html", "form");
function beforeRender() {
// ???
}
}

Very easy to do in your default.ctp layout file:
An example to automatically include .css files per controller and/or controller/action (because I had this lying around, easily adaptable to .js files):
<head>
...
<?php
if (is_file(WWW_ROOT . 'css' . DS . $this->params['controller'] . '.css')) {
echo $html->css($this->params['controller']);
}
if (is_file(WWW_ROOT . 'css' . DS . $this->params['controller'] . DS . $this->params['action'] . '.css')) {
echo $html->css($this->params['controller'] . '/' . $this->params['action']);
}
?>
...
</head>
Like deceze is saying, we do it using the layout, although I find our solution a bit more elegant :)
In default.ctp:
if(isset($cssIncludes)){
foreach($cssIncludes as $css){
echo $html->css($css);
}
}
if(isset($jsIncludes)){
foreach($jsIncludes as $js){
echo $javascript->link($js);
}
}
Then, in our controller actions, we define these arrays:
$this->set('cssIncludes',array('special')); // this will link to /css/special.css
$this->set('jsIncludes',array('jquery')); // this will link to /js/jquery.js
For files that need to be loaded in each view, we simply add the same type of link "statically" to the top of the layout, like:
echo $javascript->link('global');
echo $html->css('global');
This works really well for us. Good luck!
