title: How do I add custom javascript to my rails3 views?
body: <p>What is the best way to add JavaScript to my Rails3 views?  </p>
  
  <p>I would like to be able to do some processing in a controller, then craft some JavaScript based on the result and put the resulting JavaScript in a view.</p>
  
  <p>For example, I would like to get a series of lat/lng points from a database and create markers on a Google Map.  The map initialization and markers must be created in JavaScript, but interact with the view.  (This is just one example of what I am trying to accomplish. I am not looking for recommendations of gems/plugins that do Google Maps integration).</p>
  
  <p>Is there some way to render an js.erb file into the head of a particular view?  What is the "rails way" of doing this sort of thing?</p>
