一次创建新的记录和关系

Creating new record and relationships in one go(一次创建新的记录和关系)
本文介绍了一次创建新的记录和关系的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着跟版网的小编来一起学习吧!

问题描述

我有以下基本架构:

玩家

id
name

个人资料

id
player_id
email

子集

id
profile_id
alias

我的印象是在创建新记录时可以进行以下操作:

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'
]);

既然这段代码好像不行,那么有没有办法把关系记录和create方法一起保存?

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

推荐答案

基本上,您不能像看起来那么容易做到这一点.

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

在文档中,所有相关模型都是在创建基础模型之后创建的

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);

但是,如果你真的想一口气搞定,你可以覆盖Player模型中的save()方法:

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);

                });
}

然后您将数组传递给 Player 方法,例如:

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'
          )
);

虽然这不是推荐的操作.

Although this is not a recommended action.

任何地方都建议先创建基础模型,再创建相关模型.

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