我在Django 1.6应用程序中使用自定义用户模型TrackUser。当我想删除Adminpanel中的用户时，我收到此错误：
＆＃39; TrackUser＆＃39;对象没有属性＆＃39;替换＆＃39;
我已经查看了这个question，即使我们的追溯都以../django/utils/html.py结束，但我找不到解决问题的方法。
模型
class TrackUser(AbstractBaseUser, PermissionsMixin):
#User data
email = models.EmailField(unique=True)
first_name = models.CharField(max_length=75)
last_name = models.CharField(max_length=75)
tel_number = models.BigIntegerField(blank=True, null=True)
address = models.TextField(blank=True, null=True)
#User options
#True for first_name last_name
#False for last_name first_name
full_name_order = models.BooleanField(blank=True, default=True)
#Django necessities
date_joined = models.DateTimeField(default=timezone.now)
is_active = models.BooleanField(default=True)
is_admin = models.BooleanField(default=False)
is_staff = models.BooleanField(default=False)
#Sales fields
percentage_of_sales = models.IntegerField(default=0)
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = ['first_name', 'last_name']
objects = UserManager()
def get_absolute_url(self):
return reverse('user_detail', args=[self.pk])
def get_full_name(self):
if self.full_name_order:
order = (self.first_name, self.last_name)
else:
order = (self.last_name, self.first_name)
return "%s %s" % order
def get_short_name(self):
return self.first_name
def __unicode__(self):
return self.get_full_name()

答案 0 :(得分：1)
显然，问题仅在TrackUser链接到另一个模型时出现。
在其中一个模型中，我更改了__unicode__
def __unicode__(self):
return self.user
到
def __unicode__(self):
return self.user.get_full_name()
解决了这个问题
