Usage

Create module and controllers in it.

Controller example:

class UsersController extends ApiController
{
    public $safeAttributes = array(
        'id', 'first_name',  'middle_name', 'last_name', 'email', 
    );

    public function __construct($id, $module = null) 
    {
        $this->model = new User('read');
        parent::__construct($id, $module);
    }
    
    /**
     * Function returns user data
     * @method GET
     */
    public function actionView()
    {
        if (!Yii::app()->user->checkAccess('getUser')) {
            $this->accessDenied();
        }
        $this->getView();
    }
    
    /**
     * Function returns user list
     * @method GET
     */
    public function actionList()
    {
        if (!Yii::app()->user->checkAccess('getUser')) {
            $this->accessDenied();
        }
        
        $this->getList();
    }
    
    /**
     * Function creates new user
     * @method POST
     */
    public function actionCreate()
    {
        if (!Yii::app()->user->checkAccess('createUser')) {
            $this->accessDenied();
        }
        
        $this->model->setScenario('create'); 
        
        $this->create();
    }
    
    /**
     * Function updates user.
     * @method PUT
     */
    public function actionUpdate()
    {
        if (!Yii::app()->user->checkAccess('updateUser')) {
            $this->accessDenied();
        }
        
        $this->model->setScenario('update'); 

        $this->update();
    }
    
    /**
     * Function deletes user.
     * @method DELETE
     */
    public function actionDelete()
    {
        if (!Yii::app()->user->checkAccess('deleteUser')) {
            $this->accessDenied();
        }
        
        $this->model->setScenario('delete'); 

        $this->delete();
    }
    
    public function getRelations() 
    {
        return array(
            'comments'=>array(          // relation GET parameter name (...?with=comments)
                'relationName'=>'comments',  //model relation name
                'columnName'=>'comments',    //column name in response
                'return'=>'array'            //return array of arrays or array of models
            )
        );
    }
}

Get records

GET: /user - all users
GET: /user/2 - user with id=42

search and filtering

{"name":"alex", "age":"25"} — WHERE name='alex' AND age=25
[{"name":"alex"}, {"age":"25"}]  WHERE name='alex' OR age=25

The comparison operator is intelligently determined based on the first few characters in the given value. In particular, it recognizes the following operators if they appear as the leading characters in the given value:

• <: the column must be less than the given value.

• : the column must be greater than the given value.

• <=: the column must be less than or equal to the given value.

• =: the column must be greater than or equal to the given value.

• <>: the column must not be the same as the given value.
• =: the column must be equal to the given value.

Examples:

GET: /users?filter={"name":"alex"} — user with name alex
GET: /users?filter={"name":"alex", "age":">25"} — user with name alex AND age greater than 25
GET: /users?filter=[{"name":"alex"}, {"name":"dmitry"}] — user with name alex OR dmitry
GET: /users?search={"name":"alex"} — user with name contains the substring alex (alexey, alexander, alex)

relations

GET: /user/1?with=comments,posts — get user data with comments and posts array (comma separated list of relations in `with` GET parameter)
{
    "id":"1",
    "first_name":"Alex",
    "comments":[{"id":"1","text":"..."}, {"id":"2","text":"..."}],
