Re: How to make a good use of Elements and DRY principe ?
Hi Gremlin,
What you said is all correct, etc, however there is still the issue of
creating a view and element for every ajax method, which is kinda what
Christophe was getting at by wanting to call $this->renderElement()
from the controller.
This is also something that kinda annoyed me, however you could solve
this problem by adding a clever beforeFilter method to your
controller, which would set the view to an "element view", and set
layout to ajax, etc, automatically taking the action name and passing
it to the view which would load an element by that name.
Something to think about - I might try this in the future.

Re: How to make a good use of Elements and DRY principe ?
Somehow lost some of the post.
Also in views that dont have a $users variable set you can use the
element $this->renderElement( 'users_list' );
Using ajax to return html snippets would work as well. - jquery style
- $( '#element' ).load( Url/users/index ); would load the cached
element into the #element.
Remember you need to play with the RequestHandler component and either
extension parsing or request handling code to serve the ajax view in a
blank layout.
Again have fun with this stuff. Let us know what you come up with.

Re: How to make a good use of Elements and DRY principe ?
What you need to do is write an index action for your users_controller
like you would if you were NOT using ajax or reusing that action at
all.
Once you have that done, modify that function to check isset( $this-
>params['requested'] ) to see if the view action if being called via
the requestAction function.
***
function index( )
$users = $this->User->findAll( );
if( isset( $this->params['requested'] ) ){
return $users;
}
$this->set( 'users', $users );
}
Then you create an element - users_list.ctp
if( !isset( $_data ) ) {
$_data = $this->requestAction( array( 'controller' => 'users',
'action' => 'index' ) );
}
foreach( $_data as $row _) {
echo use data
}
You can then use the element in your users_controller index view file.
$this->renderElement( 'users_list', array( '_data' => $users );
For a good write up check out the bakery articles..

http://bakery.cakephp.org/articles/view/cache-elements-individually-for-each-user
http://bakery.cakephp.org/articles/view/optimizing-your-cakephp-elements-and-views-with-caching
This will show you how to create these reusable elements as well as
how to cache them based on the freshness of the model data, timestamps
and on a per user / instance basis
Enjoy.
and in other view without the $users data $this-
>renderElement( 'users_list' );

How to make a good use of Elements and DRY principe ?
Hello,
After reading the manual and other search results, i still didnt find
the way to make a good use of Elements when using Ajax.
Let's say i have a model "User" and in my controller, a method called
"index" that list my registered users. Since I'll re-use this user
list in my application, i decided to put it in a Element called
"_user_list.ctp".
So from my views/users/index.ctp, i just have to use $this-
>renderElement('_user_list', $users) and it works fine !
Now, i want to use Ajax to get that list rendered (I'm using Prototype
library for Ajax calls) into an element (div or table ..), but i can't
render an Element (views/elements/users/_user_list.ctp in this case)
directly from a controller.
So currently, i'm using a file in my view directory ( views/users/
user_list.ctp ) that is able call an Element ( views/elements/users/
_user_list.ctp ) and in my user controller, i'm using : this-
>render('user_list');
Is there any way to do it better than this ? I don't think i'm doing
it right ! ^^
A solution is that we should to be able to call renderElement() from
controllers.
function index(){
...
if($this->RequestHandler->isAjax()){
$this->renderElement('users/_user_list'); // with autoLayout set
to false automatically
}
}
