Usage
-----

[](#usage)

1. In your model, add the behavior and configure it
2. In your model, add validation rules for the attributes created by the behavior
3. In your view, create form fields for the attributes

Adding and configuring the behavior
-----------------------------------

[](#adding-and-configuring-the-behavior)

As an example, let's assume you are dealing with entities like `Book`, `Author` and `Review`. The `Book` model has the following relationships:

```
public function getAuthors()
{
    return $this->hasMany(Author::className(), ['id' => 'author_id'])
                ->viaTable('book_has_author', ['book_id' => 'id']);
}

public function getReviews()
{
    return $this->hasMany(Review::className(), ['id' => 'review_id']);
}
```

In the same model, the behaviour can be configured like so:

```
public function behaviors()
{
    return [
        [
            'class' => \voskobovich\behaviors\ManyToManyBehavior::className(),
            'relations' => [
                'author_ids' => 'authors',
				'review_ids' => 'reviews',
            ],
        ],
    ];
}
```

Relation names don't need to end in `_ids`, and you can use any name for a relation. It is recommended to use meaningful names, though.

Adding validation rules
-----------------------

[](#adding-validation-rules)

The attributes are created automatically. However, you must supply a validation rule for them (usually a `safe` validator):

```
public function rules()
{
    return [
        [['author_ids', 'review_ids'], 'each', 'rule' => ['integer']]
    ];
}
```

Creating form fields
--------------------

[](#creating-form-fields)

By default, the behavior will accept data from a multiselect field:

```
