Usage

Create a Model

create your ActiveRecord Model :

namespace app\models;


use yii\db\ActiveRecord;

/**
 * Class City
 * @package app\models
 */
class Post extends ActiveRecord
{

    /**
     * @return string
     */
    public static function tableName()
    {
        return 'posts';

    }

    /**
     * @return array
     */
    public function rules()
    {
        return [

            [['title'], 'required'],

        ];
    }


}

Create a Repository Interface

namespace app\repositories\interfaces;
use mhndev\yii2Repository\Interfaces\iRepository;

interface iPostRepository extends iRepository
{

}

Create a Repository class

namespace app\repositories;

use app\repositories\interfaces\iPostRepository;
use mhndev\yii2Repository\AbstractSqlArRepository;

class PostRepository extends AbstractSqlArRepository implements iPostRepository
{

}

or

create a Repository as a Yii component

class PostRepository extends Component implements iPostRepository
{

    const PRIMARY_KEY = 'id';

    const APPLICATION_KEY = 'id';


    use SqlArRepositoryTrait {
        init as repositoryInit;
    }


    public function init()
    {
        parent::init();

        $this->repositoryInit();
    }
}

this approach is useful when toy have a class which is already extending a class and can't extend AbstractRepository class just like yii components by using traits you can use this classes as yii component.

if your model is using sql as it's data source and your model actually is extending yii\db\ActiveRecord your repository should extend mhndev\yii2Repository\AbstractSqlArRepository.

and if your data source is mongodb and your model actually is extending yii\mongodb\ActiveRecord your repository should extend mhndev\yii2Repository\AbstractMongoArRepository.

and consider your application can use power of both sql and document-based databses (mongo)

Attach your Repository to container

Yii::$container->set(\app\repositories\interfaces\iPostRepository::class, [
    'class' => \app\repositories\PostRepository::class
]);


Yii::$container->set('postRepository', function($container, $params, $config){
    return new \app\repositories\PostRepository(new \app\models\Post());
});

if you are coding in a module you can put above code in your module bootstrap file. and also you can don't use container and create repository object every where you want like this :

$postRepository = new \app\repositories\PostRepository(new \app\models\Post());

Repository Sample Usage

sample usage which I show by using a controller.

namespace app\controllers;

use app\repositories\interfaces\iPostRepository;
use Yii;
use yii\web\Controller;
use yii\web\Response;

/**
 * PostController
 */
class PostController extends Controller
{

    /**
     * @var iPostRepository
     */
    protected $postRepository;


    /**
     * @var bool
     */
    public $enableCsrfValidation = false;


    /**
     * init
     */
    public function init()
    {
        parent::init();
        $this->postRepository = Yii::$container->get('postRepository');

        Yii::$app->response->format = Response::FORMAT_JSON;
    }

    /**
     * @return array
     */
    public function verbs()
    {
        return [
            'create'   => ['POST'],
            'delete'   => ['DELETE'],
            'update'   => ['PUT'],
            'index'    => ['GET'],
            'show'     => ['GET'],
            'delete-multiple' => ['DELETE']
        ];
    }


    /**
     * @return mixed
     */
    public function actionCreate()
    {
        $data = Yii::$app->request->post();

        $post = $this->postRepository->create($data);

        return $post;
    }


    /**
     * @param $id
     */
    public function actionDelete($id)
    {
        $this->postRepository->deleteOneById($id);
    }

    /**
     * @param $id
     * @return bool
     */
    public function actionUpdate($id)
    {
        $data = Yii::$app->request->post();

        $post = $this->postRepository->updateOneById($id, $data);

        return $post;
    }


    /**
     * @return mixed
     */
    public function actionIndex()
    {
        return $this->postRepository->searchByCriteria();
    }


    /**
     * @param $id
     * @return mixed
     */
    public function actionShow($id)
    {
        return $this->postRepository->findOneById($id);
    }


    /**
     *
     */
    public function actionDeleteMultiple()
    {
        $ids = Yii::$app->request->post()['ids'];

        $deletedCount = $this->postRepository->deleteManyByIds($ids);
    }


}
