I recently upgraded my Ruby to 3.1.2 and Rails to 7.0.3.1.我最近将 Ruby 升级到 3.1.2，Rails 升级到 7.0.3.1。

Somewhere in the changes, one problem I noticed is that my Paper Trails (paper_trails gem) info was now not working, at least with respect to the details.在更改的某个地方，我注意到的一个问题是我的 Paper Trails (paper_trails gem) 信息现在无法正常工作，至少在细节方面是这样。

None of the "changeset" data was available, as so my tests were failing.没有可用的“变更集”数据，因此我的测试失败了。

1 个解决方案

I put a "byebug" in the view that used the data and looked for what was missing.我在使用数据的视图中放置了一个“byebug”并查找丢失的内容。 Apparently my "changeset" data was all missing.显然我的“变更集”数据都丢失了。

I guessed it was a disallowed class problem, and I ultimately sat on that view breakpoint running我猜这是一个不允许的 class 问题，我最终坐在那个视图断点上运行

PaperTrail.serializer.load(change_history_by_month.object_changes) (your parameter will be different of course) PaperTrail.serializer.load(change_history_by_month.object_changes) （您的参数当然会有所不同）

until it output the right data.直到它 output 正确的数据。 The basic problem apparently was Pysch, and several disallowed classes (for example, "Psych::DisallowedClass Exception: Tried to load unspecified class: BigDecimal"), but fortunately the above will tell you the classes and you can add them to config/application.rb基本问题显然是 Pysch 和几个不允许的类（例如，“Psych::DisallowedClass Exception: Tried to load unspecified class: BigDecimal”），但幸运的是上面会告诉你这些类，你可以将它们添加到配置/应用程序.rb

Very frustrating as it was all quiet, without warnings or errors.非常令人沮丧，因为一切都很安静，没有警告或错误。

Of course, the classes aren't disallowed for nothing.当然，这些课程并不是无缘无故被禁止的。 There may be a security problem here with allowing these classes.允许这些类可能存在安全问题。
