Django Shell和Django Web App给出了不同的结果

Question

我有一个django应用程序，它一直工作正常，突然间有些事似乎被打破了。

class ClosedUserGroup(models.Model): 
    """ Preset definitions for ClosedUserGroup: 
    """ 
    is_active = models.BooleanField(default=True) 
    is_deleted = models.BooleanField(default=False) 
    created_at = models.DateTimeField(
     auto_now=True, 
     auto_now_add=True, 
     null=True, 
     default='2013-08-15 13:37:13.370030' 
    ) 
    name = models.CharField(max_length=256, default='<MISSING:CUG_NAME') 
    description = models.CharField(max_length=256) 


class Partner(models.Model): 
    id = models.IntegerField(primary_key=True) 
    is_active = models.BooleanField(default=True) 
    is_deleted = models.BooleanField(default=False) 
    created_at = models.DateTimeField(
     auto_now=True, 
     auto_now_add=True, 
     null=True, 
     default=datetime.datetime.now() 
    ) 
    name = models.CharField(max_length=256, default='<MISSING:PARTNERNAME>') 

class PartnerCug(models.Model): 
    """ Partner to ClosedUserGroup relation 
    """ 
    is_active = models.BooleanField(default=True) 
    is_deleted = models.BooleanField(default=False) 
    created_at = models.DateTimeField(
     auto_now=True, 
     auto_now_add=True, 
     null=True, 
     default='2013-08-15 13:37:13.370030' 
    ) 
    partner = models.ForeignKey(Partner) 
    cug = models.ForeignKey(ClosedUserGroup)   

class Account(models.Model): 
    """ 
     Account: 
     TODO:DESCRIPTION 
    """ 
    id = models.IntegerField(primary_key=True) 
    is_active = models.BooleanField(default=True) 
    is_deleted = models.BooleanField(default=False) 
    created_at = models.DateTimeField(
     auto_now=True, 
     auto_now_add=True, 
     null=True, 
     default=datetime.datetime.now() 
    ) 
    number = models.CharField(max_length=64) 
    submitted_by = models.ForeignKey(
     Partner, 
     db_column='submitted_by' 
    )  

在Django壳，下面的命令成功运行，并返回结果1：

from myapp.models import Account 
account_object = Account.objects.filter(id=1) 
account_object.filter(account__submitted_by__partnercug__cug=3).count() 

然而，在Django本身，我具备的功能

def get_other_accounts(): 
    """get total accounts""" 
    account_object = Account.objects.filter(id=1) 
    total_accounts = account_object.filter(account__submitted_by__partnercug__cug=3).count() 

然而，这失败错误号为DatabaseError: current transaction is aborted, commands ignored until end of transaction block，它指向该函数的最后一行。所以它的工作Django壳，但不是从Web应用程序。

Answer 1

缺失id或pk字段（主键）ClosedUserGroup型号？

我看不出如何在shell或web中工作。
