I have a Django model with a UUID as a primary key. The model has a
`get_absolute_url` implemented, which means in the Django admin, there is
a “View on Site” button on the instance detail view.
A valid “View on Site” request looks like this:
`/admin/r/2/b6a283ce-0529-4ce6-8aa8-3aa5eba4f95b/`, where the first
parameter 2, is the content type ID, and the 2nd parameter is the UUID for
a model instance. An invalid request looks like this: `/admin/r/2/bad-
uuid-that-will-not-validate/`.
If an invalid UUID is passed to this view, the view will raise an
unhandled ValidationError
[https://github.com/django/django/blob/955b7c6ba105b328f387a9d63540dbabd4a05828/django/contrib/contenttypes/views.py#L21
on this line ].
Because this view is used in the admin application, it requires a staff
member to access, so it cannot be thrown by a standard or unathenticated
user.
