django admin 中的 Unicode 错误

Question

尝试在 django 管理控制台中查看名称不是英文的对象时出现此错误。

UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-3: ordinal not in range(128)

我的 .py 文件的标题是

-*- coding: utf-8 -*-

这是代码

class Owner(models.Model):
    id = models.AutoField(primary_key=True)
    name = models.CharField(max_length=50)
    def __str__(self):
      return self.name

我四处寻找有关该主题的其他主题，并找到了以下解决方案： 我尝试将 py 文件中的编码更改为 unicode，我尝试将__str__ 写为unicode(self.name) 和u'%s',self.name。我还尝试添加具有相同组合的__unicode__ 成员。没有工作。我也尝试过再次同步数据库并弹回服务器。什么都没有。

奇怪的是名称显示在菜单中，但是当我尝试编辑对象时出现错误。

我将不胜感激。

Python 2.7、Django 1.5.2、Ubuntu 12、Postgres。

像这样更改您的代码：

class Owner(models.Model):
    id = models.AutoField(primary_key=True)
    name = models.CharField(max_length=50)
    def __unicode__(self):
        return self.name
