Should we store a history of when each mouse was in each cage?

[cxrodgers]

When we make a change, is the previous state of the database stored somewhere? Certainly this information is available in our daily database backups, but this is not the most convenient way to get a history of when every mouse was in every cage.

No, pretty sure this information is not stored. I think there is a simple revision history stored in admin "recent actions" widget, but probably not complete.

However, it's not clear how exactly this would be implemented, and it could get complicated (especially if someone accidentally chooses the wrong cage from the drop-down, and then fixes it).

There is a log of changes in django.contrib.admin.models.LogEntry.objects.all() but it doesn't have the actual data (ie, which cage), it just says that the mouse's cage (or whatever) was changed.
