I almost succeeded in getting there.
I can get the rooms i want via this command:
r = models.ForeignKey(Room, blank=True, null=True, limit_choices_to =
Room.objects.exclude(id__in=[patient.room.id for patient in
Patient.objects.filter(room__isnull=False)]) )
However, this produces an error when i put it in my Patient model:
class Patient(models.Model):
...
room = models.ForeignKey(Room, blank=True, null=True,
limit_choices_to = Room.objects.exclude(id__in=[patient.room.id for
patient in Patient.objects.filter(room__isnull=False)]) )
...
The error when i access the page is "name 'Patient' is not defined"
Any idea how i can take this last hurdle?
Thanks,
Benedict
