Duplicate Invitee object

[sander]

On March 8, I received two error emails about a duplicate Invitee object being found. It's likely about the same person. I'm not sure who it is yet, but investigation of the database should point that out.

Traceback (most recent call last):

MultipleObjectsReturned: get() returned more than one Availability -- it returned 2! Lookup parameters were {'date': <Date: Date object>, 'invitee': <Invitee: Invitee object>}
