Nicer templates with TAL-like variables

[panyasan]

Hello,

since the default templates are simply php-files, normal usage to
inject php-variables is to use, for example,

div id=?php echo $id ? /

In a previous project, I used PHPTAL and could include variables in
templates this way:

div id=${id} /

which is much more readable.

I wrote a hack to include into view.php. line 700:

/*
 * hack CB to allow for nicer, TAL-like templates,
 * e.g. input value=${value}/ instead of
 * input value=?php echo $value ?/
 */
$___content = file_get_contents($___viewFn);
$___content = preg_replace('/\${([^}]+)}/','?php echo \$$1
?',$___content);
$___tmpFn  = CACHE . md5( $___viewFn ) . .tmp;
file_put_contents ( $___tmpFn, $___content );

if (DEBUG) {
include ($___tmpFn);
} else {
@include ($___tmpFn);
}
unlink ($___tmpFn);
/** end hack **/

Now my questions are:

1) Is it possible to do this another way, without hacking cake source?
2) Has anyone integrated PHPTAL into cake yet?

Thanks,

Christian

Re: Updating HABTM relationships

[panyasan]

It IS funny that nobody seems to have this problem since many-to-many
relationships are among the most useful features of relational
databases. I have also tried to understand the source code of the model
but it is so complex I'd rather spend my time differently. I would
welcome any moves on the sides of the CakePHP developers to make HABTM
associations even more useful...

Cheers, Christian

Updating HABTM relationships

[panyasan]

This is related to
http://groups.google.ch/group/cake-php/browse_frm/thread/7f26efd9e871ddf1

I have two models, References and Folders:

class Reference extends AppModel
{
var $name = Reference;

/**
 *  associations
 **/

var $hasAndBelongsToMany = Folder;

/**
 * default: no recursive retrieval
 **/
var $recursive = 0;

}

class Folder extends AppModel
{

var $name = Folder;

var $recursive = 0;

/**
 * many-to-many association
 **/
var $hasAndBelongsToMany = Reference;

/**
 * many-to-one association
 **/
var $belongsTo = array (
Parent = array (
'className'  = Folder,
'foreignKey' = parent_id
)
);

/**
 * one-to-many association
 **/
var $hasMany = Folder;
}

and a controller method that should move References from one Folder to
another:

class ReferencesController extends AppController
{

var $name = References;
var $uses = array (Folder,Reference);

/**
 * moves references to different folder
 **/
function move ( $sourceId, $targetId, $list )
{
$ids = explode ( ,, $list );
$n = 0;
$this-Reference-recursive = 1;

foreach ( $ids as $id ) {

$data   = $this-Reference-findById ($id);
$folders= $data['Folder'];
$save   = array();
$fIds   = array();

if ( ! count ( $folders ) ) continue;

// link to target folder
$fIds[] = $targetId;

// copy all folder ids except the source folder
foreach ( $folders as $folder ) {
if ( ! array_search( $folder['id'], $fIds) and
  $folder['id'] != $sourceId ) {
$fIds[] = $folder['id'];
}
}
$this-Reference-id = $id;
$save['Folder']['Folder'] = $fIds;
$this-Reference-save($save);

}
return true;
}
}

It won't work. Nothing is saved.Is there a fundamental misconception on
my part? The task remove association x should be a trivial one, but
there is nothing in the documentation, as far as I could see.

I am using model_php4.php from 1.0.1.2708 (I could not upgrade the rest
because for some reason the cake gets stuck in some long loop so I
reverted to 0.10... for the rest of the code).

Thanks,

Christian
