Question

我是Laravel的新手，

我正在尝试播种一个表，而工匠总是返回代码255。

这是我的代码

<?php

use App\Grade;
use Illuminate\Database\Seeder;

class GradeSeeder extends Seeder {

    public function run()
    {
        //This doesn't even work
        DB::table('Grade')->delete();
//      Grade::create(['id' => '1','name' => "5 Kyu",'order' => 2]);
    }
}

DatabaseSeeder.php

class DatabaseSeeder extends Seeder {

    public function run()
    {
        Model::unguard();
        //Seed the countries
        $this->call('CountriesSeeder');
        $this->command->info('Seeded the countries!');
        $this->call('GradeSeeder');
        $this->command->info('Seeded the grades!');
    }

突击队使用

php artisan db:seed --class=GradeSeeder
or
php artisan db:seed // In this case seeding countries works but mine don't

以下是模型：

class Grade extends Model {

    protected $table = 'Grade';
    public $timestamps = true;

    protected $fillable = [
        'name',
        'order'
    ];

}

这是迁移

class CreateGradeTable extends Migration {

public function up()
{
    Schema::create('Grade', function(Blueprint $table) {
        $table->increments('id');
        $table->string("name")->unique();
        $table->tinyInteger("order");

    });
}

public function down()
{
    Schema::drop('Grade');
}
}

有没有办法记录发生的事情。使用Artisan的255个代码修复bug并不是那么好！
我的代码出了什么问题？我刚评论了创建行以丢弃任何数据问题。我的表“成绩”存在并且是空的！

有两个明显不一致的地方：

使用模型的create方法添加的每个列都必须是可填充的，而id则不是。你根本不应该传递它（除非你真的需要由于某种原因），因为它被定义为迁移中的主键，因此自动递增以便它自己填充。所以这应该足够Grade::create('name' => '5 Kyu', 'order' => 2]);
迁移未定义任何时间戳列，但您的模型已protected $timestamps = true;。因此，要么在迁移中添加$table->timestamps()，要么在模型中将$timestamps设置为false。

我安装了一个干净的Laravel副本，并运行了您发布的迁移，创建了模型和种子类，修复了上面列出的问题后，运行php artisan db:seed --class=GradeSeeder时没有任何错误。
