The Owner objects are all attached to a User through their user attribute. So, we say to get_object_or_404 “when you look for an Owner, check to see that the User attached to http://www.coffhampton.com/2021/01/12/what-is-agile-software-development/ it has the username that I want” by specifying user__username.

Our get method will then use that username to grab the Owner associated with that user. This get_object_or_404 function allows us to do just that, with a little something special added for ease of use.
