README

Installation

The preferred way to install this extension is through composer.

Either run

php composer.phar require mdmsoft/yii2-ar-behaviors "~1.0"

or add

"mdmsoft/yii2-ar-behaviors": "~1.0"

to the require section of your composer.json file.

Query Scope

QueryScopeBehavior will automatically attached to ActiveQuery via Yii::$container. You can use this behavior to create query scope from ActiveRecord.

class Sales extends ActiveRecord
{
    ...
    public static function defaultScope($query)
    {
        $query->andWhere(['status' => self::STATUS_OPEN]);
    }

    public static function bigOrder($query, $ammount=100)
    {
        $query->andWhere(['>','ammount',$ammount]);
    }
}

----
// get all opened sales
Sales::find()->all(); // apply defaultScope

// opened sales and order bigger than 200
Sales::find()->bigOrder(200)->all();

ExtendedBehavior

Extend Activerecord with out inheriting 😀 . This behavior use to merge two table and treated as one ActiveRecord.

Example: We have model CustomerDetail

/**
 * @property integer $id
 * @property string $full_name
 * @property string $organisation
 * @property string $address1
 * @property string $address2
 */
class CustomerDetail extends ActiveRecord
{
    
}

and model Customer

/**
 * @property integer $id
 * @property string $name
 * @property string $email
 */
class Customer extends ActiveRecord
{
    
    public function behaviors()
    {
        return [
            [
                'class' => 'mdm\behaviors\ar\ExtendedBehavior',
                'relationClass' => CustomerDetail::className(),
                'relationKey' => ['id' => 'id'],
            ],
        ];
    }
}

After that, we can access CustomerDetail property from Customer as their own property

$model = new Customer();

$model-name = 'Doflamingo';
$model->organisation = 'Donquixote Family';
$model->address = 'North Blue';

$model->save(); // it will save this model and related model

RelationBehavior

Use to save model and its relation.

class Order extends ActiveRecord
{
    public function getItems()
    {
        return $this->hasMany(Item::className(),['order_id'=>'id']);
    }

    public function behaviors()
    {
        return [
            [
                'class' => 'mdm\behaviors\ar\RelationBehavior',
                'beforeRSave' => function($item){
                    return $item->qty != 0;
                }
            ],
        ];
    }
}

usage

$model = new Order();

if($model->load(Yii::$app->request->post()){
    $model->items = Yii::$app->request->post('Item',[]);
    $model->save();
}

RelationTrait

Similar with RelationBehavior

class Order extends ActiveRecord
{
    use \mdm\behavior\ar\RelationTrait;

    public function getItems()
    {
        return $this->hasMany(Item::className(),['order_id'=>'id']);
    }

    public function setItems($value)
    {
        $this->loadRelated('items', $value);
    }

    public function beforeRSave($item)
    {
        return $item->qty != 0;
    }
    
}

usage

$model = new Order();

if($model->load(Yii::$app->request->post()){
    $model->items = Yii::$app->request->post('Item',[]);
    $model->save();
}
