进入 Container.php 行 752:Class RoleTableSeeder 不存在错误,当试图在 Laravel 中播种角色时
Getting In Container.php line 752: Class RoleTableSeeder does not exist error, when trying to seed a role in Laravel
目前,我正在尝试为我的应用程序创建角色,不幸的是我遇到了一些麻烦。每当我 运行 php artisan 迁移 --seed 时,我都会收到我在标题中写的错误。老实说,我觉得我搞砸了一些非常简单的东西,比如名字,但我就是找不到我的错误。如果有任何帮助,我将不胜感激。
User.php 型号:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class User extends Model implements Authenticatable
{
public function roles(){
return $this->belongsToMany('App\Role');
}
}
Role.php 型号:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Role extends Model
{
public function users(){
return $this->belongsToMany('App\User');

用户table:
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('first_name');
$table->string('last_name');
$table->string('username');
$table->string('password');

角色table:
public function up()

Schema::create('roles', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('description')->nullable()->default(null);
$table->timestamps();

role_user table
public function up()
{

如评论中所述:
运行: composer dump-autoload
.
如果抛出Composer\Exception\NoSslException
异常,可能需要在composer dump-autoload
.
之前运行composer config -g -- disable-tls true
我遇到了和上面一样的问题
composer 命令没有成功。
在 Laravel 5.5 我 运行
php artisan cache:clear
然后我所有新创建的播种机 类 都被发现了
我在 PH 7.2.* 和 Laravel 5.5.* 上遇到了同样的问题。*
解决方案非常简单 - 使用命名空间:
php artisan db:seed --class=Modules\{moduleName}\Database\Seeders\{className}DatabaseSeeder
也在这里:
$this->call('Modules\{moduleName}\Database\Seeders\{className}TableSeeder');
