Laravel中如何配置fake-car扩展在CarFactory生成汽车伪数据

Laravel pelmered/fake-car 工厂配置完整方案

1、先安装依赖扩展包

开发环境下执行composer命令：
composer require pelmered/fake-car --dev

2、CarFactory.php 配置方案

Provider注册代码直接写在工厂的definition()方法开头即可，无需放到Car模型中，完整工厂代码参考：

<?php

namespace Database\Factories;

use Illuminate\Database\Eloquent\Factories\Factory;

class CarFactory extends Factory
{
    protected $model = \App\Models\Car::class;

    public function definition()
    {
        // 这里注册fake-car provider
        $this->faker->addProvider(new \Faker\Provider\Fakecar($this->faker));
        $v = $this->faker->vehicleArray();

        return [
            // 你可以根据自己的表字段调整以下返回值，合并原有需求即可
            'name' => $v['brand'] . ' ' . $v['model'],
            'founded' => $this->faker->biasedNumberBetween(1998,2017, 'sqrt'),
            'description' => $this->faker->paragraph(),
            'vehicle_type'      => 'car',
            'vin'               => $this->faker->vin,
            'registration_no'   => $this->faker->vehicleRegistration,
            'type'              => $this->faker->vehicleType,
            'fuel'              => $this->faker->vehicleFuelType,
            'brand'             => $v['brand'],
            'model'             => $v['model'],
            'year'              => $this->faker->biasedNumberBetween(1998,2017, 'sqrt'),
        ];
    }
}

如果需要全局注册Provider，避免每个工厂都重复写注册代码，可以在app/Providers/AppServiceProvider.php的register()方法中添加以下配置：

public function register()
{
    $this->app->extend(\Faker\Generator::class, function ($faker) {
        $faker->addProvider(new \Faker\Provider\Fakecar($faker));
        return $faker;
    });
}

全局注册后，所有工厂都可以直接调用fake-car提供的faker方法，无需再单独注册Provider。
