Ruby on rails RSpec ActiveStorage:错误ActiveRecord:：RecordNotFound:无法'；找不到带有'；id'；

嗨，伙计们，我能得到一些帮助来找出我的RSpec测试出了什么问题吗。我在互联网上到处找，没有找到任何能说明我为什么会犯这个错误的原因

我要做的是测试一个实例变量是否有来自数据库的数据。当测试到达创建活动记录和活动存储Blob的制造商时，就会发生错误。我已经添加了数据库清理器gem，但不确定是否有什么东西弄乱了它，或者在使用RSpec、活动存储和DBcleaner时遗漏了什么

奇怪的是，我有另一个测试，也创建了相同的制造对象，我没有得到错误，你会看到下面。如果我在下面注释掉测试，那么其他测试运行得很好。任何帮助都将不胜感激。在这个问题上被困了几个小时：$

更新：我试图调查图形制造商运行后发生的情况，以及我使用附件查看附件时发生的情况？方法每一份文件都附呈。所有四个文件都作为附件返回。我原以为清理器会有问题，所以我添加了rails\u助手，以便在每次测试完成后清理所有文件

config.after(:each) do
 DatabaseCleaner.clean
 ActiveStorage::Attachment.all.each { |attachment| attachment.purge }
end 

这将在每次测试运行后获取所有附件并删除附件和blob。但这并没有起到任何作用。仍然不确定发生了什么

任何帮助都将不胜感激

谢谢：）

工厂的问题是，属性值在文件加载时只计算一次。然后，它们被所有对象重用

thumbnail_image ActiveStorage::Blob.create_after_upload!(...).signed_id

在这里用一个街区

thumbnail_image { ActiveStorage::Blob.create_after_upload!(...).signed_id }

---

这样，对于每个新制作的对象，您将获得自己的blob。
