RSpec ActiveStorage：错误 ActiveRecord::RecordNotFound：找不到 ActiveStorage::Blob 和 'id'
RSpec ActiveStorage: Error ActiveRecord::RecordNotFound: Couldn't find ActiveStorage::Blob with 'id'
大家好，我能得到一些帮助来弄清楚我的 RSpec 测试出了什么问题吗？我在互联网上到处寻找，但没有找到任何可以说明我收到此错误的原因。
我想做的是测试一个实例变量是否有一些来自数据库的数据。当测试到达创建活动记录和 ActiveStorage 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 但不确定是不是有什么问题，或者我在使用 RSpec、活动存储和 DBcleaner 时遗漏了什么。
st运行ge 是什么，我有另一个测试也创建了相同的制造对象，但我没有收到您将在下面看到的错误。如果我注释掉下面的测试，其他测试运行得很好。任何帮助将非常感激。坚持了几个小时：$
更新：我试图调查图形制作者之后发生的事情 运行 以及当我使用附件查看附件时？方法每个文件实际上是附加的。所有四个文件都按附件返回。我以为清洁器会发生一些事情，所以我添加到 rails_helper 以在每次测试完成后清除所有文件。
config.after(:each) do
DatabaseCleaner.clean
ActiveStorage::Attachment.all.each { |attachment| attachment.purge }
end
这应该会抓取所有附件并在每次测试运行后删除附件和 blob。但这没有做任何事情。仍然不确定发生了什么。
如有任何帮助，我们将不胜感激。
谢谢:)

您工厂的问题是 属性 值仅在文件加载时评估一次。然后它们被重新用于所有对象。
thumbnail_image ActiveStorage::Blob.create_after_upload!(...).signed_id
在这里使用一个块
thumbnail_image { ActiveStorage::Blob.create_after_upload!(...).signed_id }
这样，对于每个新制作的对象，您都会得到它自己的 blob。
