从 rails 3.2 升级到 rails 4.2 之前的测试套件

Question

我最近尝试将我的 Rails 应用程序从 Rails 3.2 更新到 Rails 4.2。在升级之前，我所有的测试套件都运行得很好，但是在更新之后我得到了一些奇怪的东西。每次我尝试运行测试时都会发生相同的错误

谁能帮我解决这个问题？

删除该 Fixtures 后，我得到另一个错误，请参阅

:( 我从 rails 3.2 到 4.02 进行了渐进式更新，然后从 4.02 到 4.1，一切正常，然后在 rails 4.2 我得到了同样的错误

Answer 1

我在 github 上的 rails 存储库中发布了这个问题，他们回答我这是一个错误，将在 4.2.1 版本中发布

目前您可以通过这样做来纠正此问题。 row[key] = value.gsub("$LABEL", label.to_s) if value.is_a?(String) 在 activerecord 库中的文件 fixture.rb 的第 636 行
