Question

我正在使用[Nwidart] [1]模块软件包，并且正在尝试使用工厂创建播种机。但是，当我尝试运行php artisan db:seed时，出现此错误

调用未定义函数Modules \ Products \ Database \ Seeders \ factory（）

这是我的ProductsDatabaseSeeder.php

<?php

namespace Modules\Products\Database\Seeders;

use Illuminate\Database\Seeder;
use Illuminate\Database\Eloquent\Model;
use Modules\Products\Models\Product;

class ProductsDatabaseSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        Model::unguard();

        factory(Product::class, 10)->create();
    }
}

我的ProductFactory

<?php

/** @var \Illuminate\Database\Eloquent\Factory $factory */

use Faker\Generator as Faker;
use Modules\Products\Models\Product;

$factory->define(Product::class, function (Faker $faker) {
    return [
        'title' => $this->faker->title,
        'price' => $this->faker->randomNumber(3),
    ];
});

我的Product.php

<?php

namespace Modules\Products\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Product extends Model
{
    use HasFactory;

    protected $fillable = [];
}

完全错误

  Call to undefined function Modules\Products\Database\Seeders\factory()

这是我改变后得到的

    factory(Product::class, 10)->create();

到

    Product::factory()->count(10)->create();

从Laravel 8开始，您可能会用到-使用HasFactory特性-您将需要调用

Product::factory()->create()

为了运行工厂
