php Laravel 5.3 db:seed 命令根本不起作用

Laravel 5.3 db:seed command simply doesn't work

提问by Peter

I do everything by-the-book:

我做所有的事情：

1. Installed fresh Laravel 5.3.9 app (all my non-fresh apps produce the same error)

2. run php artisan make:auth

3. create migrations for a new table `php artisan make:migration create_quotations_table --create=quotations

   Schema::create('quotations', function (Blueprint $table) {
       $table->increments('id');
   
       $table->string('text');
   
       // my problem persists even with the below two columns commented out
       $table->integer('creator_id')->unsigned()->index('creator_id');
       $table->integer('updater_id')->unsigned()->index('updater_id');
   
       $table->softDeletes();
       $table->timestamps();
   });
   

4. Then I run php artisan migrate

5. Then I define a new seed php artisan make:seeder QuotationsTableSeeder

1. 安装了新的 Laravel 5.3.9 应用程序（我所有的非新应用程序都产生相同的错误）

2. 跑 php artisan make:auth

3. 为新表创建迁移`php artisan make:migration create_quotations_table --create=quotations

   Schema::create('quotations', function (Blueprint $table) {
       $table->increments('id');
   
       $table->string('text');
   
       // my problem persists even with the below two columns commented out
       $table->integer('creator_id')->unsigned()->index('creator_id');
       $table->integer('updater_id')->unsigned()->index('updater_id');
   
       $table->softDeletes();
       $table->timestamps();
   });
   

4. 然后我跑 php artisan migrate

5. 然后我定义一个新种子 php artisan make:seeder QuotationsTableSeeder

The complete content of the file, after I add a simple insert:

文件的完整内容，在我添加一个简单的插入之后：

<?php

use Illuminate\Database\Seeder;

class QuotationsTableSeeder extends Seeder
{
/**
 * Run the database seeds.
 *
 * @return void
 */
public function run()
{
    DB::table('quotations')->insert([
        'text' => str_random(10),

    ]);
}
}

1. Then I run php artisan db:seed

6. 然后我跑 php artisan db:seed

问题

it simply doesn't work. No feedback presented, no errors in log file. The probem persists in both my local environment (Win7, newest WAMP server) and my Digital Ocean VPS powered by Ubuntu 16.04. All the above steps I took in several separate apps - for no result. Also under Laragon 2.0.5 server.

它根本不起作用。没有反馈，日志文件中没有错误。该探测器在我的本地环境（Win7，最新的 WAMP 服务器）和我的由 Ubuntu 16.04 提供支持的 Digital Ocean VPS 中都存在。我在几个单独的应用程序中采取的所有上述步骤 - 没有结果。同样在 Laragon 2.0.5 服务器下。

what I have tried

我试过的

php artisan optimizeas suggested here.

php artisan optimize正如这里所建议的。

composer dump-autoloadi php artisan clear-compiledalso have brought no results

composer dump-autoload我php artisan clear-compiled也没有带来任何结果

I also tried to seed just following the official docs example - failed.

我还尝试按照官方文档示例进行播种 - 失败。

I added use DB;to the seed file - still no result.

我添加use DB;到种子文件 - 仍然没有结果。

Are you calling your seeder inside the DatabaseSeederclass? This way:

你在DatabaseSeeder课堂上打电话给你的播种机吗？这边走：

database/seeds/DatabaseSeeder.php

数据库/种子/DatabaseSeeder.php

class DatabaseSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        $this->call(QuotationTableSeeder::class);
    }
}

Or, add the --classoption when using the php artisan db:seedcommand, this way:

或者，--class在使用php artisan db:seed命令时添加选项，如下所示：

php artisan db:seed --class="QuotationTableSeeder"

After creating or removing your seeders, don't forget to run the following command:

创建或删除播种机后，不要忘记运行以下命令：

composer dump-autoload

If anybody else is having issues with migrating AND seeding at the same time, please try

如果其他人同时在迁移和播种方面遇到问题，请尝试

php artisan migrate:fresh --seed

Worked for me..

为我工作..
