Laravel 5 - 如何在用户注册时向多个表插入行

Question

当用户注册时,如何将行插入多个表.

我有基本的Laravel用户表.我还有一个企业表(id,business_name)和一个usersbusinesses表(id,user_id,business_id)

首先,我需要创建(db insert)用户并获取其生成的id值.

然后,我需要创建(db insert)业务并获取其生成的id值.

最后,我需要使用上面的值(user_id和business_id)在usersbusinesses表中创建一个(db insert)行

我知道我将不得不修改app/Services/Registrar.php文件,我只是不知道如何解决这个问题.当前代码仅插入到users表:

/**
 * Create a new user instance after a valid registration.
 *
 * @param  array  $data
 * @return User
 */
public function create(array $data)
{
    return User::create([
        'first_name' => $data['first_name'],
        'last_name' => $data['last_name'],
        'email' => $data['email'],
        'password' => bcrypt($data['password']),
    ]);
}

谢谢Christian

如果你想做更多,就像添加你刚刚粘贴的创建功能一样简单.

/**
 * Create a new user instance after a valid registration and do more.
 *
 * @param  array  $data
 * @return User
 */
public function create(array $data)
{
    $user = User::create([
        'first_name' => $data['first_name'],
        'last_name' => $data['last_name'],
        'email' => $data['email'],
        'password' => bcrypt($data['password']),
    ]);

    $business = Business::create([
        'name' => 'best business ever'
    ]);

    $business->owners()->sync([$user->id]);

    return $user;

}

对于倒数第二部分:

$business->owners()->sync([$user->id]);

你应该在这里阅读有关雄辩的关系.

因为你把这么多命令放在一起,我建议你阅读Laravel的Jobs/Commands.它们在Laravel文档的" 队列"部分中提到.

有关如何添加owner()方法的更新.

Business.php模型:

/**
 * Owners of the business.
 * 
 * @return \Illuminate\Database\Eloquent\Relations\BelongsToMany
 */
public function owners()
{
    return $this->belongsToMany('App\User', 'userbusinesses');
}

同样在您的Users.php模型中:

/**
 * Business this person owns.
 * 
 * @return \Illuminate\Database\Eloquent\Relations\BelongsToMany
 */
public function businesses()
{
    return $this->belongsToMany('App\User', 'userbusinesses');
}

但是,我的建议是保持内联标准并将您的数据透视表重命名为business_user,在这种情况下,您不需要belongsToMany中的第二个参数.

另请注意,我更改了保存为同步的命令.我没有意识到这是第一次多对多.
