    "id":"TEST_ID",
    "email":"user@test.local",
    "name":"Test REST User"

INSTALLATION

All of this code yo can find in demo folder.

• Unpack library folder to %YOUR_EXTENSION_PATH%/yii-rest-api
• Update yours config/main.php

Add new path of alias at the beginning

YiiBase::setPathOfAlias('rest', '%YOUR_EXTENSION_PATH%/yii-rest-api/library/rest');

Add extension service to preload and components sections

'preload' => array('restService'),  

'components' => array(  
    'restService' => array(  
        'class'  => '\rest\Service',  
        'enable' => strpos($_SERVER['REQUEST_URI'], '/api/') !== false, // for example
    ),  
),

Change routing settings

'urlManager'=>array(
    'urlFormat'      => 'path',
    'showScriptName' => false,
    'baseUrl'        => '',
    'rules' => array(
        array('%YOUR_CONTROLLER%/index',  'pattern' => 'api/%YOUR_CONTROLLER%', 'verb' => 'GET', 'parsingOnly' => true),
        array('%YOUR_CONTROLLER%/create', 'pattern' => 'api/%YOUR_CONTROLLER%', 'verb' => 'POST', 'parsingOnly' => true),
        array('%YOUR_CONTROLLER%/view',   'pattern' => 'api/%YOUR_CONTROLLER%/<id>', 'verb' => 'GET', 'parsingOnly' => true),
        array('%YOUR_CONTROLLER%/update', 'pattern' => 'api/%YOUR_CONTROLLER%/<id>', 'verb' => 'PUT', 'parsingOnly' => true),
        array('%YOUR_CONTROLLER%/delete', 'pattern' => 'api/%YOUR_CONTROLLER%/<id>', 'verb' => 'DELETE', 'parsingOnly' => true),
    )
),

• Update parent or specific Controller

Add behavior

public function behaviors()
{
    return array(
        'restAPI' => array('class' => '\rest\controller\Behavior')
    );
}

Overwrite render method (if need it)

public function render($view, $data = null, $return = false, array $fields = array())
{
    if (($behavior = $this->asa('restAPI')) && $behavior->getEnabled()) {
        return $this->renderRest($view, $data, $return, $fields);
    } else {
        return parent::render($view, $data, $return);
    }
}

Overwrite redirect method (if need it)

public function redirect($url, $terminate = true, $statusCode = 302)
{
    if (($behavior = $this->asa('restAPI')) && $behavior->getEnabled()) {
        $this->redirectRest($url, $terminate, $statusCode);
    } else {
        parent::redirect($url, $terminate, $statusCode);
    }
}

• Upate parent or specific ActiveRecord Model (or any other instance of CModel), if you need render rules.

Add behavior

public function behaviors()
{
    return array(
        'renderModel' => array('class' => '\rest\model\Behavior')
    );
}

Add rule

public function rules()
{
    return array(            
        array('field1,field2,field3', 'safe', 'on' => 'render'),
    );
}
