Shastra

class Shastra(models.Model): 
    something = models.IntegerField() 

    def save(self, *args, **kwargs): 
     post_content(app='shastra', content=self) 
     super(Shastra, self).save(*args, **kwargs) 


# The function being called in the override function 

def post_content(*args, **kwargs): 
    FbApiContent(content = kwargs['content']).save() 


# The model being used by the override function 

from shastra.models import Shastra 

class FbApiContent(models.Model): 

    content = models.ForeignKey(Shastra) 

と呼ばれる私のモデルの一つの保存メソッドをオーバーライドすることでした。 |、何らかの洞察力を私は感謝します

Answer 1

円形輸入。解決するか、文字列をFK引数（models.ForeignKey('app.Shastra')）として使用してください。

Answer 2

あなたは循環インポートがあるようです。

shastra\models.pyがfrom fb_api.api import *

fb_api\api.pyをやっていることは、あなただけのモジュールから1つのクラスをインポートする場合でもfrom shastra.models import Shastra

をやっているfrom fb_api.models import FbApiUser

fb_api\models.pyをやっている、全体のモジュールは、それの名前空間を埋めるために実行されます。
