Creating new record and relationships in one go

问题

I have the following basic schema:

players

id
name

profiles

id
player_id
email

subsets

id
profile_id
alias

I was under the impression the following operation was possible when creating a new record:

Player::create([
    'name' => 'Player 1',
    'profile.email' => 'player1@email.com',
    'profile.subset.alias' => 'Player 1 alias'
]);

Since this code doesn't seem to work, is there anyway to save relationships records together with the create method?

回答1:

Basically, you can't do this as easy as it looks.

In the docs, all related models are created after the base model is created

$profile = new Profile(array('email' => 'player1@email.com','alias'=>'Player 1 alias'));

$player = new Player(array('name'=>'Player 1'));

$player = $post->profile()->save($profile);

However , if you really want to do it in one go, you can overwrite the save() method in the Player model :

public function save(){
        Database::transaction(function() {
                    $profileModel = new Profile($this->profile);

                    parent::save();

                    $this->profile()->insert($profileModel);

                });
}

You will then pass the array to the Player method like :

array(
name='Player name',
profile=>array(
         email=>'player1@email.com',
         subset=>array(
           alias=>'Player 1 alias'
          )
);

Although this is not a recommended action.

Everywhere is suggested to create the base model first, then the related models.
