How to learn the code inside of ruby on rails
I want to learn the code inside of rails, can any one tell me from where i need to begin?

I am confused with all the amount of code inside all the rails, i want to understand everything in rails , how can i do it?, i am confusing with that, is anyone that have done this?<p>

the pupose is that, from where i need to start to learn the entire code, to understand, from to where the variables comes and gone, i have started learning that, but i am getting confused, is anybody that have done this?

not just use rails, want to edit it and understand, i understand that is not easy and a waste of many time, but how can this be done more correctly?
