Seeder命令不起作用Laravel 5.4

Question

我是laravel的新手我正在嘗試按照教程創建數據庫的數據庫播種器。因此，對於這一點，我已經使用php artisan make:seeder ArticlesTableSeeder命令

播種機

class ArticlesTableSeeder extends Seeder 
{ 
    public function run() 
    { 
     // Let's truncate our existing records to start from scratch. 
     Article::truncate(); 

     $faker = \Faker\Factory::create(); 

     // And now, let's create a few articles in our database: 
     for ($i = 0; $i < 50; $i++) { 
      Article::create([ 
       'title' => $faker->sentence, 
       'body' => $faker->paragraph, 
      ]); 
     } 
    } 
} 

現在，當我運行php artisan db:seed --class=ArticlesTableSeeder命令我有這個錯誤

[Symfony\Component\Debug\Exception\FatalThrowableError] Class 'Article' not found

我有一個文章modal

<?php 

namespace App; 

use Illuminate\Database\Eloquent\Model; 

class Article extends Model 
{ 
    protected $fillable = ['title', 'body']; 
} 

我在這裏做錯了什麼？我搜索了這個錯誤，發現它們的最大值是由於拼寫錯誤。我想我在這裏沒有拼寫錯誤。這段代碼有什麼問題？

幫助將不勝感激。

所有你應該做的是Article前添加\App\或簡單地添加use \App\Article

class ArticlesTableSeeder extends Seeder 
{ 
    public function run() 
    { 
     // Let's truncate our existing records to start from scratch. 
     \App\Article::truncate(); 

     $faker = \Faker\Factory::create(); 

     // And now, let's create a few articles in our database: 
     for ($i = 0; $i < 50; $i++) { 
      \App\Article::create([ 
       'title' => $faker->sentence, 
       'body' => $faker->paragraph, 
      ]); 
     } 
    } 
} 

Answer 2

use App\Article; 

class ArticlesTableSeeder extends Seeder 
    { 
     public function run() 
     { 
      // Let's truncate our existing records to start from scratch. 
      Article::truncate(); 

      $faker = \Faker\Factory::create(); 

      // And now, let's create a few articles in our database: 
      for ($i = 0; $i < 50; $i++) { 
       Article::create([ 
        'title' => $faker->sentence, 
        'body' => $faker->paragraph, 
       ]); 
      } 
     } 
    }

你錯過了，包括您的控制器內部模型，所以你得到class not found error。將該行添加到您的控制器之前

use App\Article;
