Laravel faker 语法

Question

我正在遵循一个教程，我正在尝试让 faker 将数据放入数据库中。我正在使用这个代码。

<?php

namespace Database\Factories;

use Illuminate\Database\Eloquent\Factories\Factory;

/**
 * @extends \Illuminate\Database\Eloquent\Factories\Factory<\App\Models\Listing>
 */
class ListingFactory extends Factory
{
    /**
     * Define the model's default state.
     *
     * @return array<string, mixed>
     */
    public function definition()
    {
        return [
            'title' => $this->faker->sentence(),
            // 'tags' => 'Laravel, API, Backend',
            // 'company' => $this->faker()->company(),
            // 'location' => $this->faker()->city(),
            // 'email' => $this->faker()->companyemail(),
            // 'website' => $this->faker()->url(),
            // 'description' => $this->faker()->paragraph(5),

        ];
    }
}

我只是将其限制在标题中，试图找出我的问题是什么。 这是我遇到的错误。

` INFO  Seeding database.


   Illuminate\Database\QueryException

我尝试准确复制代码，但找不到错误。 预先感谢您的帮助。

我只是想在数据库中植入一些虚假数据进行测试

除非

tags

列可为空，否则您需要传递它才能从工厂创建模型。

Listing::factory()->create(['tags' => 'Some, Tags, Here']);
