Laravel 8 + 修补匠 : How to create dummy data

Question

在之前的 Laravel 版本中，我在 tinker 中使用了这个:

php artisan tinker
factory(App\Banana::class, 3)->create();

但是在 Laravel 8 中，它给出了这个错误:`PHP 错误:找不到类 'Database/Factories/bananaFactory'

请问如何使用 tinker 在 Laravel 8 中创建虚拟数据？谢谢。

Answer 1

您可以尝试以下步骤:

1. 在您的 Banana 模型中添加了 HasFactory，如下所示:

<?php
namespace App\Models;

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

class Banana extends Model
{
    use HasFactory;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'title', 'description'
    ];
}

1. 创建工厂

- php artisan make:factory BananaFactory --model=Banana

1. 在生成 BananaFactory 后转到该路径:

<?php
 
namespace Database\Factories;
 
use App\Models\Post;
use Illuminate\Database\Eloquent\Factories\Factory;
use Illuminate\Support\Str;
 
class BananaFactory extends Factory
{
    /**
     * The name of the factory's corresponding model.
     *
     * @var string
     */
    protected $model = Banana::class;
 
    /**
     * Define the model's default state.
     *
     * @return array
     */
    public function definition()
    {
        return [
            'title' => $this->faker->title,
            'description' => $this->faker->text,
        ];
    }
}

1. 之后运行这个命令:

 composer dump-autoload

1. 然后打开终端并运行:

php artisan tinker
Banana::factory()->count(3)->create()
