Question

这里是回溯更新代码

类基料（models.Model）： CREATED_BY = models.ForeignKey（用户，默认= User.pk，related_name =“（app_label）s _％（class）s_creator”） created_by = models.ForeignKey（User，default = User.pk，related_name =“（app_label）s _％（class）s_editor”） created_at = models.DateTimeField（auto_now_add = TRUE） modified_at = models.DateTimeField（auto_now_add = TRUE）

class Meta: 
abstract = True 

class Department(Base): 
dept_id = models.AutoField(primary_key=True) 
name = models.CharField(max_length=60, unique=True) 
description = models.TextField() 

def __unicode__(self): 
return str(self.name)

Answer 1

必须提供当你创建一个部门时，你可以使用user。您可以访问以当前用户为request.user，如果你是在一个视图

user = request.user 

或从数据库中获取的任何用户，如果你是在外壳测试

user = User.objects.get(id=1) # get 

然后创建department：

department = Department(name='test', 
         description='test', 
         user=user, 
         ) 

最后，您的default=User.pk不正确。对于用户实例，您可以访问user.pk，但类属性User.pk不是您认为的当前用户的pk。
