Ask HN: Transitioning from Front-End to a Rails Dev, what should I expect?

I’ve been doing front-end coding for a few years now but recently have been trying to teach myself Ruby on Rails on the side. I have already gone through a few resources…all the Codecademy lessons for Ruby, CodeSchools “Try Ruby” and “Ruby Bits” series, “Mr. Neighborly’s Humble Little Ruby Book” to learn the basics of Ruby…and now I’m just getting to the tip of the iceberg with Rails. I’m currently working through M. Hartl’s popular “Rails Tutorial” and the most recent edition of “Agile Development with Rails”.

I’m hoping to transition to a Junior Rails developer role but am not sure of what general knowledge I need to have or what I should expect when applying to these positions. Because I’m familiar with some aspects of web development, should I be able to land a job more easily with my front-end experience and learn the ropes from my future employer or would I benefit more from buckling down for a few months and learning the inner-workings of the framework?
