在十月 CMS 中使用 Faker

Question

我在十月 CMS 中创建服务插件。我有 2 个转发器字段（包裹、邮递员）。我使用 Faker Plugin 在数据库中插入虚拟数据但出现错误

为 foreach() 提供的参数无效

这是我的种子代码

<?php namespace Sepehr\Service\Updates;

use Sepehr\Service\Models\Service;
use Faker;
use October\Rain\Database\Updates\Seeder;

class SeedAllTable extends Seeder
{

    public function run()
    {
        $faker = Faker\Factory::create();
        $service = new Service();

        $service->user_id = 1;
        $service->manager_id = 1;
        $service->sender_postal_code = $faker->postcode();
        $service->sender_address = $faker->address();
        $service->status_id = $faker->numberBetween(1, 6);

        foreach ($service->packages as $package) {
            $package['receiver_postal_code'] = $faker->postcode();
            $package['receiver_address'] = $faker->address();
            $package['weight_id'] = $faker->numberBetween(1, 3);
            $package['post_type_id'] = $faker->numberBetween(1, 3);
            $package['distribution_time_id'] = $faker->numberBetween(1, 3);
            $package['special_services_id'] = $faker->numberBetween(1, 3);
            $package['price'] = 0;
            $package['package_type_id'] = $faker->numberBetween(1, 3);
            $package['insurance_type_id'] = $faker->numberBetween(1, 3);
        }
        $service->save();

这不是假货什么的问题。

问题是service是新记录，packages第一次是空白，所以模型不知道它的定义/模式所以你需要将它分配为数组，然后它会自动转换为json

class User extends Model
{
   // make sure your field is jsonable
   protected $jsonable = ['packages'];

现在换包替换

$service->status_id = $faker->numberBetween(1, 6);

foreach ($service->packages as $package) {
    $package['receiver_postal_code'] = $faker->postcode();
    $package['receiver_address'] = $faker->address();
    $package['weight_id'] = $faker->numberBetween(1, 3);
    $package['post_type_id'] = $faker->numberBetween(1, 3);
    $package['distribution_time_id'] = $faker->numberBetween(1, 3);
    $package['special_services_id'] = $faker->numberBetween(1, 3);
    $package['price'] = 0;
    $package['package_type_id'] = $faker->numberBetween(1, 3);
    $package['insurance_type_id'] = $faker->numberBetween(1, 3);
}
$service->save();

有

// ...

$service->status_id = $faker->numberBetween(1, 6);

$packages = [];
$howManyPackges = 3;
while($howManyPackges > 0)
    $package = [];
    $package['receiver_postal_code'] = $faker->postcode();
    $package['receiver_address'] = $faker->address();
    $package['weight_id'] = $faker->numberBetween(1, 3);
    $package['post_type_id'] = $faker->numberBetween(1, 3);
    $package['distribution_time_id'] = $faker->numberBetween(1, 3);
    $package['special_services_id'] = $faker->numberBetween(1, 3);
    $package['price'] = 0;
    $package['package_type_id'] = $faker->numberBetween(1, 3);
    $package['insurance_type_id'] = $faker->numberBetween(1, 3);
    $packages[] = $package;
    $howManyPackges--;
}
$service->packages = $packages;

$service->save();

// ...

它将为转发器packages添加3条记录

它应该添加包数组，jsonable 会将其转换为json。
