从Rails3.2升级到Rails4.2之前的测试套件

Question

我最近尝试将我的Rails应用程序从Rails3.2更新到Rails4.2。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。每次尝试运行测试时，都会发生相同的错误

rake db:fixtures:load --trace
** Invoke db:fixtures:load (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:fixtures:load

我在github的rails存储库中发布了这个问题，他们回答说这是一个bug，将在4.2.1版本发布

目前，你可以纠正这一点，这样做。row[key]=value.gsub（“$label”,label.to_s)如果value.is_a？（String）位于activerecord库文件fixture.rb的第636行
