title: IS there any Django app that notify the user about something that happened in your web, and ask him to perform an action?
body: <p>I mean, there's any generic app that you can use to make notifications like when in Facebook, someone adds you as friend, or invite you to an event?</p>
  
  <p>Basically, I need to show to the user this type of notification for different contents type, with the possibility to do some custom actions (ignore, accept, etc) different for each one.</p>
  
  <p>I wonder if someone have done this before, so I can plug it and create a type of notification simply passing the text of the notification, the options that must show and the views to call for each option.</p>
  
  <p>Thanks.</p>
