Question

我在用Django中文用户名查询时遇到错误：“用户不存在”。相关代码：

reload(sys)
sys.setdefaultencoding('utf-8')

user_name = sheet.cell_value(r, 7).replace(' ', '')
equipment.eq_receiver = User.objects.get(user_name=user_name)

class User(AbstractUser):
    user_id = models.AutoField(primary_key=True)
    user_name = models.CharField(max_length=20)

回溯：

Traceback (most recent call last):
File "C:\Python27\lib\site-packages\django\core\handlers\exception.py", line 41, in inner
  response = get_response(request)
File "C:\Python27\lib\site-packages\django\core\handlers\base.py", line 187, in _get_response

  self.model._meta.object_name
DoesNotExist: User matching query does not exist.

在Debugger中，我得到了 user_name 的值：

user_name={unicode}u"邵阳"

然后在Pycharm的 Watches 视图中，我尝试了其他一些查询，但结果让我困惑：

User.objects.get(user_name=u'\u90b5\u9633')={User}邵阳  #unicode of '邵阳'
User.objects.get(user_name=u'邵阳')={DoesNotExist}User matching query does not exist.
User.objects.get(user_name='邵阳')={User}邵阳
User.objects.get(user_name=user_name)={DoesNotExist}User matching query does not exist.

Django匹配查询不存在 - 关于编码
