I have just released a Model pagination plugin for the Recess Framework. This allows you to effortlessly paginate your models using only one annotation on the Model class. It works like this:

//The model

/**
* !Paginate Limit: 5
*/
class Book extends Model {

}

//The controller

/**
* !Route GET, books
*/
function listBooks() {
$book = new Book();
$books = $book->equals('genre', 'adventure')->orderBy('published_at DESC')->paginate();
$paginator = $books->paginator;
}

You can request subsequent "pages" by appending "?page=2" to the request URL. In this example controller, the $books variable is a filtered ModelSet containing the appropriate records based on the requested "page" and the number of results to show per page (defined on the Model, in this case, 5). You can pass the $paginator object into the View to assist with creating pagination links. See the Paginator class for details on what properties and methods are available. Installation and usage information is available in the README file.

Enjoy!

After building a custom web app with Recess for a client of mine, I found I needed to have Model validations (which Recess does not provide built-in). So I wrote some! You can now validate Model attributes on save, insert, or update by specifying a validation annotation. Here's an example.

/**
* !ValidatesPresenceOf Fields: (title, author), On: (insert, update)
*/
class Book extends Model {
public $title;
public $author;
}

I've provide the following annotations:

!ValidatesPresenceOf Fields: (field), On: (save, insert, update)
!ValidatesNumericalityOf Fields: (field), On: (save, insert, update)
!ValidatesSizeOf Fields: (field), On: (save, insert, update), Min: 1, Max: 100
!ValidatesInclusionOf Fields: (field), On: (save, insert, update), In: (value, value2, value3)
!ValidatesExclusionOf Fields: (field), On: (save, insert, update), From: (value, value2, value3)
!ValidatesFormatOf Fields: (field), On: (save, insert, update), With: @^[a-z0-9_]+$@

These are simple implementations of the Rails validation classes. Bear in mind these are still a work in progress and have not been 100% tested. I'm using them in a current project so I'm confident they work as advertised. Be sure to read the README file on GitHub to learn how to install and use the plugin. If you like what you see, have questions, suggestions, etc, feel free to drop me a line!

I stumbled over Recess when searching for a method to handle RESTful urls with php.
I have to admit, that in general I don't like frameworks, as most of them are too large and
kind of unflexible.

Recess, as I think, changed my mind, it looks like there is a great concept behind it.
So thanks to Kris to make it available and hopefully bring it even further!

Recess's Framework is extremely similar to Spring MVC and I love it.
Unfortunately there has been much inactivity regarding it.

Key components such as validation and security are still missing and I hope to see them one day.
I'd love to start a new project with Recess but I am afraid it will have no support going into the future.

Your feedback will be greatly appreciated!]]> Thu, 27 May 2010 11:53:24 +0000 http://forums.recessframework.org/topic/145-is-recess-still-being-developed/ Return XML with Recces http://forums.recessframework.org/topic/143-return-xml-with-recces/ I would like to know where I can see an example of Recces returning an XML

This seems wrong. Blank objects should not be considered to exist.

/**

 * with the current instances properties exists. If so, it will
 * preload those values (side effects).
 * 
 * Usage:
 * $model->id = 1;
 * if($model->exists()) {
 *  die('a lonesome death');
 * }
 *
 * @return boolean
 */
function exists() {}

Here's how Model::exists() used to behave.

$user = new User();
echo ( $user->exists() ? $user->id : 0 );

1

Here's how it behaves now

$user = new User();
echo ( $user->exists() ? $user->id : 0 );

0

If there are no model column properties set, Model::exists() returns false.

Old code:

function exists() {
    $result = $this->select()->first();
    if($result !== false) {
        $this->copy($result, false);
        return true;
    } else {
        return false;
    }
}


New code:

function exists() {
    $descriptor = self::getClassDescriptor($this);
    $blank_object = true;
    foreach($this as $column => $value) {
        if(in_array($column, $descriptor->columns) && isset($value)) {
            $blank_object = false;
        }
    }
    
    if(!$blank_object) {
        $result = $this->select()->first();
        if($result !== false) {
            $this->copy($result, false);
            return true;
        } else {
            return false;
        }
    } else {
        return false;
    }
}

Logically it's the diff between 

... WHERE 1 [&& (...)]
... WHERE 0 [|| (...)]


Kris, have you considered this use case?
Do you agree with my assessment?]]> Tue, 09 Mar 2010 20:41:38 +0000 http://forums.recessframework.org/topic/127-existence-of-blank-objects/ Multi-column primary key http://forums.recessframework.org/topic/126-multi-column-primary-key/
As it stands you can only specify one column to be the primary key in a model's !BelongsTo annotation, right? Or is that just the impression i get when looking at the Recess Tools? At least the !Column annotation doesn't choke on having multiple columns as PrimaryKey.

So is this currently possible? If not, would it even be possible to include it? I wouldn't like it, if a framework dictated my database layout.]]> Tue, 09 Mar 2010 08:45:16 +0000 http://forums.recessframework.org/topic/126-multi-column-primary-key/
