I was trying to suggest that it's already a lot to learn Javascript, CSS and HTML for absolute beginners. I don't think adding Rails to the mix does anything except make things more complicated. In another comment, I added that I wouldn't use Django, either, and suggested that Meteor or Firebase are probably a better place to start brand-new developers. The fewer new things you're throwing at them in one go, the better.
And if you look at the recently published (and fairly well received) IEEE language rankings, you'll see that Ruby is ranked 9th for the number of jobs, and has Java, C#, Python, and PHP ahead of it - all languages with one or more major web frameworks. Any of them would be a better choice for someone looking for work, according to these charts.
Also, let's be honest - in the scheme of things, no-one uses Ruby on the front-end.
