 Reporting my use as requested in docs
 https://docs.djangoproject.com/en/2.1/ref/models/querysets/#extra

Comment:

 [https://docs.djangoproject.com/en/stable/ref/models/expressions/ query
 expression] for that. See TicketClosingReasons/UseSupportChannels to get
 help if the documentation isn't enough.
