content_type.views.shortcut throws exception handling invalid UUID (View on Site in admin)

[Andy Shapiro]

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 ​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.

Replicated. Thanks for the report!
