Really? That's like learning Calculus before addition and subtraction. I recommend that you learn basic computer programming before trying to learn how to manage a development scheme like Rails.

Don't try to start at the top, you will crash and burn. Start at the bottom and work upward.

There are many ways to start, and reasonable people may differ. I personally recommend that you learn Python first -- it's very approachable and it teaches you the basics first.
