Usage
-----

[](#usage)

This extension allows control over Eloquent many-to-many relations via array attributes. Each such attribute matches particular `BelongsToMany` relation and accepts array of related model IDs. Relations will be automatically synchronized during model saving.

> Note: in general such approach makes a little sense, since Eloquent already provides fluent interface for many-to-many relation synchronization. However, this extension make come in handy while working with 3rd party CMS like [Nova](https://nova.laravel.com), where you have a little control over model saving and post processing. Also it may simplify controller code, removing relation operations in favor to regular attribute mass assignment.

In order to use the feature you should add `\Illuminatech\SyncManyAttribute\SyncManyToManyAttribute` trait to your model class and declare `syncManyToManyAttributes()` method, defining attributes for relation synchronization. This method should return an array, which each key is the name of the new virtual attribute and value is the name of the relation to be synchronized.

For example:

```
