How to use django model outside of django framework?

Which one do you use: Go, Scala, Java or Ruby for web development?

• I am just a student, and I write web using Ruby on Rails and sometimes using Django, recent years. At the begining, I thought the RoR and Django are both very new things, and convenient to write the web. Recent days, I decide to learn some new thing, so I began to search on the google, I suddenly found the world has changed! Seems there are a lot of new stuffs are used by people very popular! I found: [1] Many engineers use Go language (just with its standard library "net/http") to write web without framework. [2] Play framework, driven by scala and Java, very similiar to RoR and Django. [3] Square, Heroku seems has used a lot of Go language on backend. [4] Linkedin declare that they start to use Play framework. [5] Twitter use heavy Scala on backend. [6] Facebook uses its own language "Hack" instead of PHP. I am not expert, but from the first feeling: J2EE, Spring, RoR, Django seems start to go down. If I have time to learn a new stuff from zero just for fun, which one you recommand? [a] Go language [b] Scala language and Play framework [c] Facebook's Hack If I hope to get a job, which one you recommand? [a] Go language [b] Scala language and Play framework [c] Facebook's Hack [d] J2EE [f] Spring framework. [g] Or keep sharpen RoR I know there are also a lot of other new stuffs, such as Grails framework, Gorilla, Gocraft/web, Revel, Martini... Any recommendation is welcoming...

• Answer:

  A lot depends on where you want to work. There's a lot to be said about those pieces as RoR and Django in the larger scheme of SOA architecture. There's regional distinctions as to what to use as well. Go is great. Scala's fine. Hack is still (Mostly) PHP (or if you care, C in PHP wrappers). Java's an industry standard and the multitude of frameworks wrapped on top of it. And Ruby on Rails is right up there with all of them. What I'll tell you, and everyone else is the same: Find the problem space you like, find the culture you want to be part of. If you're looking at enterprise level development, go with Scala/Java. If you're looking for more startupy feelings, try something a little smaller. Whatever you do. Just be VERY comfortable in whatever you're doing. It's not necessarily important to pick the right one, just to pick one at this stage of your career. If you're looking to work in the States, there's a fantastic number of RoR companies, both large, small, enterprise, and startupy. If you know how to do something well, you'll find people wanting to hire you. Heck. I get calls because I've been working with Lua forever, and Lua's not really a largely popular language. You'll find jobs with whatever you choose. Don't worry about that.
