将伪装价值设置为少于另一个伪造的田地

Question

您好，我正在创建一个用于折扣型号的工厂。我有两个字段（'Original_price'和'discounted_price'）。我在工厂中使用RandomFloat来创建一个随机数，其中有2个小数为“ Original_price”。如何将“ discounted_price”设置为始终比'Original_price'的值始终较低？

目前，“ discounted_price”的伪装值与“ ointer_price”相同，因为我找不到一种方法。

<?php

namespace Database\Factories;

use App\Models\Category;
use App\Models\User;
use Illuminate\Database\Eloquent\Factories\Factory;

/**
 * @extends \Illuminate\Database\Eloquent\Factories\Factory<\App\Models\Discount>
 */
class DiscountFactory extends Factory
{
    /**
     * Define the model's default state.
     *
     * @return array<string, mixed>
     */
    public function definition()
    {
        return [
            'user_id' =>User::factory(),
            'category_id' => Category::factory(),
            'title' => $this->faker->sentence(),
            'slug' => $this->faker->slug(),
            'body' => '<p>' . implode('</p><p>', $this->faker->paragraphs(6)) . '</p>',
            'original_price' => $this->faker->randomFloat('2',0,2),
            'discounted_price' => $this->faker->randomFloat('2',0,2),
        ];
    }
}

我想我遇到了一个解决方案，但我不知道这是否正确。我的想法是，“ discounted_price”的最小值应为“ ointer_price”的50％，最大值应该是'onigral_price' - 5。这是正确的方法吗？

<?php

    namespace Database\Factories;

    use App\Models\Category;
    use App\Models\User;
    use Illuminate\Database\Eloquent\Factories\Factory;

    /**
     * @extends \Illuminate\Database\Eloquent\Factories\Factory<\App\Models\Discount>
     */
    class DiscountFactory extends Factory
    {
        /**
         * Define the model's default state.
         *
         * @return array<string, mixed>
         */
        public function definition()
        {
            return [
                'user_id' =>User::factory(),
                'category_id' => Category::factory(),
                'title' => $this->faker->sentence(),
                'slug' => $this->faker->slug(),
                'body' => '<p>' . implode('</p><p>', $this->faker->paragraphs(6)) . '</p>',
                $original_price = 'original_price' => $this->faker->randomFloat('2',0,2),
                'discounted_price' => $this->faker->numberBetween($min=$original_price/2, $max=$original_price-5)
            ];
        }
    }

似乎是对的，我建议您不要在数组值中混合和匹配属性分配以保持清晰

        public function definition()
        {
            $originalPrice = $this->faker->randomFloat('2', 0, 2);
            $discountMin = $originalPrice / 2;
            $discountMax = $originalPrice - 5;

            return [
                'user_id' =>User::factory(),
                'category_id' => Category::factory(),
                'title' => $this->faker->sentence(),
                'slug' => $this->faker->slug(),
                'body' => '<p>' . implode('</p><p>', $this->faker->paragraphs(6)) . '</p>',
                'original_price' => $originalPrice,
                'discounted_price' => $this->faker->numberBetween($discountMin, $discountMax)
            ];
        }
