How can I generate older rails application when current version is 3.0.3

Question

I have 2 different Rails Rubygems installed on my Linux OS [2.3.8 and 3.0.3], but the current active Rails version is 3.0.3. So is it possible to generate Rails app using 2.3.8 style generator:rails testapp not new one: rails new testapp?

Answer 1

You can tell Rails to use version 2.3.8 like this:

rails _2.3.8_ testapp
