Getting the Dojo 1.5 rich text editor dijit.Editor working nicely with Rails 3

I could not find much on the web and it took me a little time to get everything working (especially saving edited content) so I'll share some code, hopefully to save you some time. In apps/views/layouts/application.html.erb I added some boilerplate (with non-editor stuff not shown) to be included with each rendered page:
  <link rel="stylesheet" type="text/css"
  <link rel="stylesheet" type="text/css"
    href= "">
  <script type="text/javascript" src=""
          djConfig="parseOnLoad: true">
  <script type="text/javascript">
Then in my view I create an inline rich editor using:
<div dojoType="dijit.Editor" id="editor1"
     extraPlugins="[{name: 'save', url: 'task'}]">
  <%= raw(@task_current.content) %>
It is very important to use the raw method because Rails 3 automatically makes safe HTML encoded strings for any result returned by <%= ... %>. Also notice the url value of 'task': this sends the content data to the index method of the task_controller. This method checks to see if an incoming request is an XHR POST and if so gets the raw content:
if request.xhr?
   if session[:task_id]
     task = Task.find(session[:task_id])
For brevity I did not show any error handling.
