两个外键，如何用laravel eloquent映射 [英] two foreign keys, how to map with laravel eloquent

问题描述

我在 MySQL 中有两个表，其中第一个称为用户，第二个称为游戏.表结构如下.

I have two tables in MySQL, where the first one is called users and the second one is called games. The table structure is as follows.

用户

• id(主要)
• 电子邮件
• 密码
• 真实姓名

游戏

• id(主要)
• user_one_id(国外)
• user_one_score
• user_two_id(国外)
• user_two_score

我的游戏桌有两个对外关系，两个用户.

My games table is holding two foreign relations to two users.

我的问题是如何为这个表结构建立模型关系??- 根据 laravel 文档，我应该在模型内部创建一个函数并将其与其关系绑定

My question is how do I make the model relations for this table structure?? - According to the laravel documentation, I should make a function inside the model and bind it with its relations

例如

public function users()
{
    $this->belongsTo('game');
}

但是我似乎无法在文档中找到任何告诉我如何处理两个外键的内容.就像我上面的表格结构一样.

however I can't seem to find anything in the documentation telling me how to deal with two foreign keys. like in my table structure above.

我希望你能帮助我一路走来.

I hope you can help me along the way here.

谢谢

推荐答案

迁移:

$table->integer('player1')->unsigned();
$table->foreign('player1')->references('id')->on('users')->onDelete('cascade');
$table->integer('player2')->unsigned();
$table->foreign('player2')->references('id')->on('users')->onDelete('cascade');

还有一个模型:

public function player1()
{
    $this->belongsTo('Game', 'player1');
}
public function player2()
{
    $this->belongsTo('Game', 'player2');
}

编辑按照用户 deczo 的建议将游戏"更改为游戏".

EDIT changed 'game' to 'Game' as user deczo suggested.
