부분을 해결하기 위해 어떤 경로를 어떻게 이동해야합니다

# encoding: utf-8 
import datetime 
from south.db import db 
from south.v2 import DataMigration 
from django.db import models 

class Migration(DataMigration): 

    def forwards(self, orm): 
     Order = models.get_model('orders', 'Order') 

     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 = (
      'gender', 'birth_date', 'first_name', 'last_name', 'street_number', 

Answer 1

당신은 안 직접 모델과 상호 작용할 수 있습니다. django.models을 사용하지만 해당 버전의 모델이 잘못된 상태입니다. 마이그레이션 상태에서 모델의 상태를 원한다면 0002. south manual에는 orm 매개 변수를 통해 모델에 액세스해야한다고 나와 있습니다.

우리는 사용자 모델에 액세스하는 데 orm.User를 사용합니다. 이는 마이그레이션이 생성 된 시점의 사용자 버전을 제공하므로, 향후 마이그레이션을 실행하려면 완전히 다른, 새로운, 사용자 모델. source

그래서 당신은 다음과 같이 마이그레이션을 다시 작성해야합니다 같은

orders = orm.Order.objects.all() 

심지어을 :

Order = orm.Order 

난 그냥 마이그레이션 디렉토리를 삭제
