title: How do I autoload an external gem in Rails?
body: <p>I recently externalized my rails models outside of my rails-app into a gem (models_gem).</p>
  
  <p>When my rails project imports the models_gem, i have to do a: require 'model' , in order to use the model.  How can I automatically import all the models that are in my models_gem ??</p>
