Hi Masklinn, this is a good point and also crossed my mind. The two
apps definitely don't belong as one because they serve very different
purposes. All I was trying to do is minimize data replication since a
profile can point to room object rather than a charfield. One idea I
had was to create an Office model in the resources app that would link
a Profile to a Room, and remove the office field from the profile.
Then this relation would be in the resources app and the circular
dependency would go away. But that doesn't sit with me well either,
seems unnatural.
