I was researching a simple way to trace ruby code, so the problem I tried to solve (as usual) is to understand the code infront of me even more, so I need some monitor, when I open a rails server and I navigate around, I need to see the methods executed and where is it located, I need to see that in realtime. Turns out the solution is very simple, as Ruby has TracePoint module, you can use it to log any thing gets called in your application, so adding this snippet to your rails initializers or anywhere before your application starts.
