Is it realistic for me to expect that I might be able to use Scala for a full stack? [closed]

Question

I am thinking of writing a web app in Scala using the Play! framework for the front end, and probably MongoDB for the backend. Is there any reason why I wouldn't be able to / want to use scala for the entire application? In other words, are there areas where I would be forced to use ruby or php? I like the idea of just having the full stack in Scala, but I don't really know if that is realistic or not.

I am very new to web development, but have experience in java, which is why play framework and scala seem like good choices. But I apologize if my questions doesn't exactly make sense.

Answer 1

To make it short: I don't see any reason why you should use PHP or Ruby. You can do it completely in Java (Play1.x) or Scala. If you prefer Scala I would recommend Playframework 2.0.
