與經理過濾

Question

我有一個經理（AccountManager），我想過濾FK用戶，但用戶鏈接在賬戶表中。我試過以下.filter(account.user=user)，但是這給我一個錯誤。

這樣做的正確方法是什麼？代碼如下。

謝謝

class AccountManager(models.Manager): 
    def for_user(self, user): 
     return self.get_query_set().filter(account.user=user) 

class Transaction(models.Model): 

    account = models.ForeignKey('Account', 
           related_name='transactions') 

    amount = models.DecimalField(max_digits=10, decimal_places=1) 
    objects = AccountManager() 


class Account(models.Model): 


    OPEN, FROZEN, CLOSED = 'Open', 'Frozen', 'Closed' 
    status = models.CharField(max_length=32, default=OPEN) 
    #FK 
    user = models.OneToOneField(User) 

Answer 1

class AccountManager(models.Manager): 
    def for_user(self, user): 
     return self.get_query_set().filter(account__user=user)
