Usage

[](#usage)

### SyncRelationBehavior

[](#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

[](#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:

```
