Question

我正在使用laravel的Cache门面来建立预订数据，然后再将预订存储在数据库中。

我使用以下函数在缓存中生成预订，该函数创建一个UUID，然后将其作为预订参考。

一旦生成参考，我就将预订邮政编码设置如下

几乎所有其他预订都有冲突的邮政编码，这是缓存中另一个预订的邮政编码。

例如，当第一个客户出现时，他们的邮政编码是正确设置的。第二个客户将设置他们的邮政编码，即使我使用唯一的预订参考，这也会覆盖第一个客户的邮政编码。

缓存存储在数据库中

{
    return $this->respondSuccess([
        "booking_reference" => $this->booking->generate()

    $booking = $this->booking->setReference($bookingReference)->get();

    $booking->setPostcode($this->request->postcode);
}

    $bookingAsArray = $this->parser->toArray($this);
