[Answer]-Tracing back foreign-keys

You can get all of the runners in a race by doing:

self.runner_set.select_related('person')

This will contain all of the runners, and will have a JOIN to the person table.

When you use .values(), then it gives you back the foreign key values, which is not what you want.

If you want, you can use the related_name="runners" within your foreign key to Race. Then you’ll be able to access it via self.runners...
