From a Django, Rails, Flask, Sinatra guy; Rails is going to be fun if you leave your pre-conceived notions at the door. Rails is not Django, and Ruby is not Python, and any attempts to make it behave like how it's not supposed to behave will cause pain. However, if you can play per Rails rules(and you should), that would be a very pleasant experience. How are you learning Rails? Since you are an experienced programmer, the official rails guide will be the fastest way to get a feel of rails - http://guides.rubyonrails.org/getting_started.html

The link above is the modified, famous "blog in 10 minutes". When I was starting, I found it very pleasant as it covers the 20% of the Rails which you use 80% of the time.
