Some things wont have cards. Expecting to have cards will mean they break some of the time.

Just use the times. We dont need to query the database for related objects.

Here is the code:

def get_duration(self):
    if self.start_time == None:
          return timedelta(0)
    if self.end_time == None:
          return timezone.now() - self.start_time
    eturn self.end_time - self.start_time

Notice the use of self. And the name of the function. These are intentional.

Rather make a base class and inherit the functionality.

Why is this getting complicated again?

Why are cards here at all?

Write loosely coupled code. Dont write code that relied on things it doesn't need. This stuff will break.
