我正在尝试解决我的Rails应用程序中的当前问题。我的rails应用程序正在使用RailsAdmin，尝试通过通用的RailsAdmin选项上传文件后出现问题。
因此，此应用使用的是Ruby 2.5.3，RailsAdmin 1.4.2和Rails 5.2.3。
似乎我正在运行一个无提示错误...也许是一种模型验证或类似的购买，我什至在调试模式下都没有得到任何相关的输出。
问题是我不确定如何调试此问题，因为这些操作是在rails-admin gem中处理的。 即使我将RubyMine与调试功能一起使用，我也不知道在哪里设置断点，因为这是由gem处理的。我试图破坏一些初始化程序，但是当然没有达到预期的效果。
所以我将感谢所有提示和帮助，这些提示和帮助可帮助我调试此问题！
最诚挚的问候，
Tunnelblick
