title: Django: Sending Signals - Not understanding the documentation
body: <p>I have 2 listeners defined:</p>
  
  <pre><code>def update_dashbaord_modified_date(sender, **kwargs):
      """Listen for changes to Goal, Action, etc. since we
      want to update the date modified on Dashbaord when a change occurs."""
      ... do something ...
  
  post_save.connect(update_dashbaord_modified_date) # Register to listen for post_save signals
  post_delete.connect(update_dashbaord_modified_date) # Register to listen for post_delete signals
  </code></pre>
  
  <p>And now, after there is a change to a Goal or adds a Goal (model class Goal), I want that save to send a signal. How is this implemented. I don't understand the documentation for it.</p>
  
  <p>Thanks</p>
