RE: javascript injection, it's totally optional and in years of doing rails dev work I've never used it (I presume you're talking about the 'remote' option). Actually, the vast majority of my rails stuff recently has been RESTish (or at least Backbone compatible) json endpoints with a CoffeeScript frontend. The front and back end in that case are totally decoupled (though rails does do some nice things to help you organize your frontend code). This would have been hard a few years ago but I've found that as time has wore on rails has become quite a bit more forgiving when you disagree with DHH, e.g.. you can use whatever templating language, testing framework or ORM you like, and there will be others who made the same choice you can look to for support. It's still opinionated about defaults, but you can switch out whatever libraries you like these days, for the most part.
