title: How do I "force" my Rails 3 app to use 1.9.2
body: <p>I have setup Rails 3.0.3 and installed Ruby 1.9.2 with rvm and set rvm to use 1.9.2 by default.</p>
  
  <p>However, when I create a new rails app and check the environmental variables it still reflects ruby 1.8.7, how do I update this to 1.9.2?</p>
