Hi, first congrats for chosing RoR, it will be continious learning procoess, In start i can give you an intro to Ruby on Rails, then I can guide you on daily basis, you can start with any online Tutorial or any Book. And we can have some timings fixed daily in which you can ask questions or discuss some points.
There can be two ways:
1. Geeting hands dirty with Ruby language, HTML/ CSS / JS for some time ( depending on hiw much you spend on daily basis) and then start Ruby on Rails.
2. Directly start RoR, and learn ruby, html, css, Js along with it.
I would recomend to go for first option.
Choice will be yours and good luck for the futurr towards Ruby on Rails.
