NamedScope Behavior for CakePHP

This NamedScope behavior for CakePHP allows you to define named scopes for a model,
and then apply them to any find call. It will automagically create a model method,
and a method for use with the _findMethods property of the model.

NamedScope is now packaged as a plugin, so as to allow easier management - particularly with Git submodules - and to support tests.

Install:

Just create a 'named_scope' directory in your app/plugins directory, and drop these files and directories into it.

If your application is managed via Git, you can use NamedScope as a submodule. Just cd into your app directory, and run:

git submodule add git://github.com/joelmoss/cakephp-namedscope.git plugins/named_scope

Once the submodule is added we need to register this submodule using init:

git submodule init

From now on we can update all the submodules using the following command:

git submodule update

Example:

I have a User model and want to return only those which are active. So I define this in my model:

var $actsAs = array(
    'NamedScope.NamedScope' => array(
        'active' => array(
            'conditions' => array(
                'User.is_active' => true
            )
        )
    )
);

Then call this in my User controller:

$active_users = $this->User->active('all');

or this:

$active_users = $this->User->find('active');

You can even pass in the standard find params to both calls:

$active_users = $this->User->active('all', array(
    'conditions' => array(
        'User.created' => '2008-01-01'
    ),
    'order' => 'User.name ASC'
));

or:

$active_users = $this->User->find('active', array(
    'conditions' => array(
        'User.created' => '2008-01-01'
    ),
    'order' => 'User.name ASC'
));
