I don't mean to be spamming you like this, just thought you might be
interested in this result:
So I created the same tables (n_test_staff and n_nics_groups) in the
default gibbs database. I removed the using part in the form statement
(form = StaffForm(instance = Staff.objects.using('gold').get(username
=current_staff), so now it looks like form = StaffForm(instance =
Staff.objects.get(username =current_staff) and it works fine,
everything is getting displayed in the view perfectly!!
Problem is that those two tables have to live in the other database -
gold. Not sure how to proceed from here. I may just have to remove the
foreign key reference for the time being and update it manually in the
code, until a fix can be found for this.
