i've got that added in and ran a syncdb and i'm stuck on this err:
django.core.exceptions.ImproperlyConfigured:
InventoryAdmin.readonly_fields[0], 'BarCode' is not a callable or an
attribute of 'InventoryAdmin' or found in the model 'Inventory'.
but I'm not seeing anything wrong with my readonly list a in my code.
