Multiple versions of Rails with rbenv

Question

Is there a way using rbenv to have multiple rails versions sitting side by side with the same version of ruby? For example, I'd like to be able to have one source folder using rails4, and another folder using rails3.

I can very easily install the two different versions of rails, but I just don't know how to call different versions of rails per folder.

Ah, I figured it out. By manually defining the Gemfile in each of the different source directories with different versions of rails, you can then call bundle exec rails and it will load it in the context of each gemfile.

If someone needs more information about how to make this work, I wrote [a blog post](http://www.relativkreativ.at/articles/managing-multiple-rails-versions-with-rbenv) about it. – Michael Trojanek May 02 '14 at 16:08

You probably should use bundler for this. Or if you really want to call rails with the desired version a la magic, take a look at rbenv-gemset.
