Laravel 灯塔现在注入日期时间

Question

有没有办法将 now datetime 注入到突变中？

像这样：

customerUpsert(input: CustomerInput! @spread): Customer
@upsert(model: "App\Models\Customer")
@inject(context: ???, name: "customer_since")

我在 laravel 灯塔中制作了一个 Scalar 来满足我的需要：

<?php

namespace App\GraphQL\Scalars;

use GraphQL\Error\Error;
use GraphQL\Type\Definition\ScalarType;

class CustomValue extends ScalarType
{

    public function serialize($value): string
    {
        return $value;
    }

    public function parseValue($value): string
    {
        return $value;
    }


    public function parseLiteral($valueNode, $variables = [])
    {
        $map = [
            "now" => now(),
        ];

        if (!array_key_exists($valueNode->value, $map)) {
            throw new Error(
                "Query error: Invalid custom value",
                $valueNode
            );
        }

        return $map[$valueNode->value];
    }
}

如果需要，您可以添加要默认设置的其他值。这是它的用法示例：

input CustomerInput {
  id: ID
  name: String!
  date: CustomValue = "now"
}
