Yii2 Relation Behavior

Easy linking and sync relationships many-to-many.

Installation

Run the Composer command to install the latest stable version:

composer require frostealth/yii2-relation-behavior @stable

Behaviors

  • SyncRelationBehavior
  • EasyRelationBehavior

Usage

SyncRelationBehavior

Attach the behavior to your model:

public function behaviors()
{
    return [
        SyncRelationBehavior::className(),
    ];
}

Use the sync method to construct many-to-many associations. The sync method accepts an array of IDs.

$model->sync('categories', [2, 5, 9]);

EasyRelationBehavior

The EasyRelationBehavior extends the SyncRelationBehavior.

Attach the behavior to your model:

public function behaviors()
{
    return [
        [
            'class' => EasyRelationBehavior::className(),
            'relations' => ['categories'],
            'suffix' => 'ids', // by default
        ],
    ];
}

public function rules()
{
    return [
        ['categoriesIds', 'each', 'rule' => ['integer', 'integerOnly' => true]],
    ];
}

Just add your $suffix to the relation name and you will get associated ids:

$categoriesIds = $model->categoriesIds; // [1, 3, 4]

// linking
$categoriesIds = [2, 3, 5];
$model->categoriesIds = $categoriesIds;
$model->save();

Add control to view for managing related list.

Without extensions it can be done with multiple select:

<?php $categories = ArrayHelper::map(Category::find()->all(), 'id', 'name') ?>
<?= $form->field($model, 'categoriesIds')->dropDownList($categories, ['multiple' => true]) ?>
