Hi all, The Exception#cause <https://docs.ruby-lang.org/en/2.5.0/Exception.html#method-i-cause> method has been added to Ruby 2.1.0 back in 2013. Since then Rails has adopted it to replace the #original_exception method in a few classes such as the ActiveSupport::Rescuable, and I believe we could take a step further to help debug an app in development. One low-hanging fruit that I see is to add the ability to show causes in the DebugExceptions view. I have made a proof-of-concept implementation to see if it could be really useful. Here is a screenshot of what it looks like:

Let me know what you all think. Thanks, Yuki -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.
