将带有外键约束的用户表填充到 Laravel 5.4 中的另一个表中

Question

我在我的用户表的帐户表上添加了一个带有外键约束的列 account_id。

对于注册过程，我现在希望首先将email 插入到帐户表中。然后我想用account_id 和所有其他注册信息填充用户表。

我的 RegisterController.php 看起来像这样：

<?php

namespace App\Http\Controllers\Auth;

use App\Account;
use App\User;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Validator;
use Illuminate\Foundation\Auth\RegistersUsers;

class RegisterController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Register Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles the registration of new users as well as their
    | validation and creation. By default this controller uses a trait to
    | provide this functionality without requiring any additional code.
    |
    */

    use RegistersUsers;

    /**
     * Where to redirect users after registration.
     *
     * @var string
     */
    protected $redirectTo = '/home';

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest');
    }

    /**
     * Get a validator for an incoming registration request.
     *
     * @param  array  $data
     * @return \Illuminate\Contracts\Validation\Validator
     */
    protected function validator(array $data)
    {
        return Validator::make($data, [
//            'name' => 'required|string|max:255',
            'email' => 'required|string|email|max:255|unique:users',
            'password' => 'required|string|min:6|confirmed',
        ]);
    }

    /**
     * Create a new user instance after a valid registration.
     *
     * @param  array  $data
     * @return \App\User
     */
    protected function create(array $data)
    {
       $account = Account::create([
            'email' => $data['email'],
        ]);


        return User::create([
//            'name' => $data['name'],
            'email' => $data['email'],
            'password' => bcrypt($data['password']),
            'account_id' => $accounts['id'],
        ]);
    }
}

我的 Account.php 如下所示：

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Account extends Model
{
  public function user()
    {
        return $this->hasOne('User','account_id');
    }
}

而我的 Users.php 看起来像这样：

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    use Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'email', 'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];

    public function account()
    {
        return $this->belongsTo('Account');
    }

}

这似乎不起作用。我是 Laravel 的新手，在这里有点迷路。任何指针都会很棒！

请在顶部添加以下行

use App\Account;

您需要在控制器上定义模型名称。这就是您出错的原因。

更新

当您像这样在RegisterController 中使用namespace 时：

namespace App\HTTP\Controllers\Auth;

那么你的RegisterController.php文件必须在App\HTTP\Controllers\Auth里面。

当您使用这样的工匠命令创建控制器时：

php artisan make:controller RegisterController

然后，默认情况下 RegisterController.php 在 App\HTTP\Controllers\ 创建。所以，你需要把namespace改成

namespace App\HTTP\Controllers;

那么你的问题就解决了。
