title: Can I manually trigger signals in Django?
body: <p>I've written some signals in my Django app that are supposed to send out an email when a particular model instance is created or modified, but the signal receiver function doesn't seem to be responding; at any rate, I'm not getting any emails through (although I have already checked that I'm able to send emails with my current configuration).</p>
  
  <p>Anyhow; I wondered, is it possible to manually send a post_save signal for debugging purposes, rather than trying to trigger it by creating a new model instance each time? Thanks!</p>
