Laravel eloquent: Update A Model And its Relationships

Question

With an eloquent model you can update data simply by calling

$model->update( $data );

But unfortunately this does not update th

Answer 1

You can implement the observer pattern to catch the "updating" eloquent's event.

First, create an observer class:

class RelationshipUpdateObserver {

    public function updating($model) {
        $data = $model->getAttributes();

        $model->relationship->fill($data['relationship']);

        $model->push();
    }

}

Then assign it to your model

class Client extends Eloquent {

    public static function boot() {

        parent::boot();

        parent::observe(new RelationshipUpdateObserver());
    }
}

And when you will call the update method, the "updating" event will be fired, so the observer will be triggered.

$client->update(array(
  "relationship" => array("foo" => "bar"),
  "username" => "baz"
));

See the laravel documentation for the full list of events.

Answer 2

You may try something like this, for example a Client model and an Address related model:

// Get the parent/Client model
$client = Client::with('address')->find($id);

// Fill and save both parent/Client and it's related model Address
$client->fill(array(...))->address->fill(array(...))->push();

There are other ways to save relation. You may check this answer for more details.
