问题描述
我有两个这样的模型:
class School(models.Model):
name = models.CharField(max_length = 50)
def __unicode__(self):
return self.name
class Education(models.Model):
user_profile = models.ForeignKey(UserProfile, related_name='Education')
school = models.OneToOneField(School)
def __unicode__(self):
return self.school
当我想添加教育到用户配置文件与django管理员这个错误eccour:
When I want add a education to userprofile with django admin this error eccour:

如何解决这个错误?
推荐答案
要解决这个问题,你需要 __ unicode __
返回 str
(不是一个对象)。
To fix this you need __unicode__
to return str
(not an object).
def __unicode__(self):
return unicode(self.school)
