     orders = Order.all_objects.select_related('buyer') 
     orders = orders.filter(first_name__isnull=True) 
     orders = orders.filter(buyer__isnull=False) 
     orders = orders.exclude(payment_status="UNFINISHED") 

     userfields = (

Answer 1

あなたはいけませんそのようなモデルを直接操作することができます。 django.modelsを使用していますが、そのバージョンのモデルの状態が間違っています。マイグレーション中のモデルの状態を希望します0002。 south manualには、ormパラメーターを使用してモデルにアクセスする必要があると記載されています。

ユーザーモデルにアクセスするためにorm.Userを使用することに注意してください。これは、この移行が作成されたときのユーザーのバージョンを示しているため、今後移行を実行する場合は、完全に異なる、新しい、ユーザーモデル。 source

ですから、このような移行書き換える必要があります。

orders = orm.Order.objects.all() 

を、さらに次のように：

Order = orm.Order
