【问题描述】：

将数据播种到我的数据库时出现此错误。显然我有 2 个模型 bookings 和 bookingstatus 模型。bookingstatus 播种器运行良好，并且播种状态非常好，但是当涉及到预订时，数据无法播种。这是弹出的错误

ErrorException 

  Undefined variable:

      Illuminate\Foundation\Bootstrap\HandleExceptions::handleError("Undefined variable: ", "F:\Main Server\htdocs\voskillproject\database\seeders\BookingsSeeder.php")

      Database\Seeders\BookingsSeeder::run()

这是我的 BookingsFactory

<?php

namespace Database\Factories;

use App\Models\Bookings;
use Illuminate\Database\Eloquent\Factories\Factory;

class BookingsFactory extends Factory
{
    /**
     * The name of the factory's corresponding model.
     *
     * @var string
     */
    protected $model = Bookings::class;

    /**
     * Define the model's default state.
     *
     * @return array
     */
    public function definition()
    {
        return [
            'is_booking'=>0,
            'full_name'=>$this->faker->unique()->name,
            'location'=>$this->faker->location,
            'phone'=>$this->faker->number,
            'is_booking'=>3,
            'email'=>$this->faker->safeEmail,
            'date'=>$this->faker->date,
            'event_id'=>$this->faker->event_id,
            'event_details'=>$this->faker->paragraph,
            
        ];
    }
}

这是我的数据库播种器

<?php

namespace Database\Seeders;

use App\Models\Role;
use App\Models\Bookingstatus;
use Illuminate\Database\Seeder;
use Database\Seeders\RoleSeeder;
use Database\Seeders\Userseeder;
use Database\Seeders\BookingsSeeder;
use Database\Seeders\BookingstatusSeeder;

class DatabaseSeeder extends Seeder
{
    /**
     * Seed the application's database.
     *
     * @return void
     */
    public function run()
    {
        $this->call([
            BookingsSeeder::class,
            BookingstatusSeeder::class,
        ]);
        \App\Models\Bookingstatus::factory()->hasbookings(10)->create();

        
    }
}

我不明白代码哪里出错了

【解决方案1】：

我知道问题出在哪里 1.首先在预订工厂我必须将faker详细信息更改为此

return [
            'is_booking'=>0,
            'full_name'=>$this->faker->unique()->name,
            'location'=>$this->faker->address,
            'phone'=>$this->faker->numerify('###-###-####'),
            'is_booking'=>3,
            'email'=>$this->faker->safeEmail,
            'date'=>$this->faker->unique()->dateTime()->format('Y/m/d'),
            'event_id'=>$this->faker->randomDigit(),
            'event_details'=>$this->faker->paragraphs(2, true),
            
        ];

我也应该在 bookingstatus 工厂的顶部导入此代码

使用 Illuminate\Support\Str;
