Laravel Nova 没有坚持新模式

Question

我运行遇到了一个奇怪的问题，即 Laravel Nova 无法保留我的任何模型。尝试在全新 Nova 安装上保存用户并使用创建的默认用户资源仍然失败。（尽管更新用户条目有效）。

我在尝试创建新用户时遇到的错误是：

No query results for model [App\User].

查看 Laravel Nova Core，负责的文件是：vendor/laravel/nova/src/Http/Controllers/ResourceStoreController.php 在此函数中，如果我尝试手动保存新模型

dd((new User())->create(['name' => '', 'email' => '', etc]));

它成功输出了模型，但仍然没有将它保存在数据库中。

将相同的代码放在 Tinker / 任何其他 Web 路由中时，会成功创建一个新模型并将其保存在数据库中。

我的app\Nova\User.php:

<?php

namespace App\Nova;

use Laravel\Nova\Fields\ID;
use Illuminate\Http\Request;
use Laravel\Nova\Fields\Text;
use Laravel\Nova\Fields\Gravatar;
use Laravel\Nova\Fields\Password;

class User extends Resource
{
    /**
     * The model the resource corresponds to.
     *
     * @var string
     */
    public static $model = 'App\User';

    /**
     * The single value that should be used to represent the resource when being displayed.
     *
     * @var string
     */
    public static $title = 'name';

    /**
     * The columns that should be searched.
     *
     * @var array
     */
    public static $search = [
        'id', 'name', 'email',
    ];

    /**
     * Get the fields displayed by the resource.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function fields(Request $request)
    {
        return [
            ID::make()->sortable(),

            Gravatar::make(),

            Text::make('Name')
                ->sortable()
                ->rules('required', 'max:255'),

            Text::make('Email')
                ->sortable()
                ->rules('required', 'email', 'max:254')
                ->creationRules('unique:users,email')
                ->updateRules('unique:users,email,{{resourceId}}'),

            Password::make('Password')
                ->onlyOnForms()
                ->creationRules('required', 'string', 'min:8')
                ->updateRules('nullable', 'string', 'min:8'),
        ];
    }

    /**
     * Get the cards available for the request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function cards(Request $request)
    {
        return [];
    }

    /**
     * Get the filters available for the resource.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function filters(Request $request)
    {
        return [];
    }

    /**
     * Get the lenses available for the resource.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function lenses(Request $request)
    {
        return [];
    }

    /**
     * Get the actions available for the resource.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function actions(Request $request)
    {
        return [];
    }
}

用户模型:

<?php

namespace App;

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

class User extends Authenticatable
{
    use Notifiable;

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

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

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];
}

我的用户table迁移

<?php

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

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

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

知道是什么导致了这样的保存操作吗？有关其他信息，我的设置如下：

Laravel (5.8) 新星 (2.5) PHP 7.2 MySQL 版本 15.1 分发 10.4.6-MariaDB

Answer 1

使用批量赋值时不初始化新模型class，调用静态方法::create()

\App\User::create(['name' => '', 'email' => '', etc]);

还要确保用户模型中的所有属性都是可填充的

protected $fillable = [
    'name', 'email', 'password', // Add the rest
];

或者你也可以做我做的事

protected $guarded = []; // yolo

希望对您有所帮助

原来问题出在我的 MariaDB 安装上。最近升级了它，我想可能有一些配置导致了混乱。从 MariaDB 转移到 MySQL 8 解决了这个问题。
