Debugging on a production server in Rails

how do you efficiently debug a live server in rails, be it on a beta server?

I tried changing the file directly on the server and restarting the application, but the changes did not seem to take effect, or took a lot of time (caching?)

I also tried to do "script / server production" locally, but it is very slow

Another option is code and deployment, but it is very inefficient.

Does anyone know how they do this efficiently?

I will answer your question, even if I do not agree with this method of hotpatching the server code :)
