Question

我想问一下错误“函数Illuminate \ Database \ Eloquent \ Model :: setAttribute（）的参数太少，传递了1个”

我尝试注册用户，我使用php artisan make：auth来建立我的身份验证。但是，我在用户迁移中添加了一个字段。我尝试使用uuid。这是我的代码：

用户模型

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
use App\Traits\Uuids;
class User extends Authenticatable
{
use Notifiable;
use Uuids;
/**
 * The attributes that are mass assignable.
 *
 * @var array
 */
protected $guarded = ['id'];
protected $table = 'users';
protected $fillable = [
    'name', 'email', 'password','phone_number',
];


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

注册控制器

<?php

namespace App\Http\Controllers\Auth;

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

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',
        'phone' => 'required|numeric|min:8',
        'password' => 'required|string|min:6|confirmed',
        'password_confirmation' => 'required|same:password',
    ]);
}

/**
 * Create a new user instance after a valid registration.
 *
 * @param  array  $data
 * @return \App\User
 */
protected function create(array $data)
{
    return User::create([
        'name' => $data['name'],
        'email' => $data['email'],
        'phone_number' => $data['phone'],
        'password' => Hash::make($data['password']),
    ]);
}


}

用户迁移

<?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateUsersTable extends Migration
{
/**
 * Run the migrations.
 *
 * @return void
 */
public function up()
{
    Schema::create('users', function (Blueprint $table) {
        $table->uuid('id');
        $table->string('name');
        $table->string('email')->unique();
        $table->string('password');
        $table->integer('phone_number');
        $table->rememberToken();
        $table->timestamps();
    });
}

/**
 * Reverse the migrations.
 *
 * @return void
 */
public function down()
{
    Schema::dropIfExists('users');
}
}

Uuids特性

<?php
namespace App\Traits;

trait Uuids 
{
/**
 * 
 */
protected static function boot()
{
    parent::boot();
    static::creating(function ($model) {
        $model->{$model->uuid} = 
        str_replace('-', '', \Uuid::generate(4)->string);
    });
}
}

请给我建议。谢谢。

Answer 1

由于以下原因而发生此错误

$data = ['user_id' => 1,'content' => 'content'];
$data = User::create($data);

在这种情况下，如果我们的数组变量名称为data并创建$ data = User :: create（$ data）;，则会发生此错误。是数据，此后创建laravel返回数据对象，然后两个数据都变得模棱两可，因此引发错误。

Answer 2

我找不到与您如下所述的属性或魔术属性有关的任何引用（例如方法getUuidAttribute）

$model->{$model->uuid} = str_replace('-', '', \Uuid::generate(4)->string);

所以，我假设上面的代码将编译为

$model->{null} = str_replace('-', '', \Uuid::generate(4)->string);

我猜您在寻找$model->id，其数据库列的类型为uuid。但是，显然，您不能拥有动态数据库列名称，因为它根本是错误的。如果您的代码片段正常运行，则为动态列示例

$model->'6b324d55-433c-455a-88b6-feb2ee6c3709' = 'c3bec822-e5ee-4d91-b1a3-f5f552fd004a';

有些不对，对吧？看起来像这样会更好。

$model->id = 'c3bec822-e5ee-4d91-b1a3-f5f552fd004a';

当然，请按照以下步骤操作最新的代码段

<?php
namespace App\Traits;

trait Uuids {

    // to make model run this 'boot' method, append it with your trait name
    protected static function bootUuids() { // <-- bootUuids
        // parent::boot();

        static::creating(function ($model) {
            $model->id = str_replace('-', '', \Uuid::generate(4)->string);
        });
    }
}

函数Illuminate \ Database \ Eloquent \ Model :: setAttribute（）的参数太少，已传递1
