在 django admin 中访问数据库时出现 UnicodeEncodeError

UnicodeEncodeError while accessing db in django admin

尝试通过管理员访问数据库时出现此错误

UnicodeEncodeError at /admin/nota_app/demographic/

Exception Type: UnicodeEncodeError
Exception Value: 'ascii' codec can't encode character u'\x8e' in position 0: ordinal not in range(128)

这是我的模型:

@python_2_unicode_compatible
class Demographic(models.Model):
    status = models.CharField(max_length = 100)
    region = models.CharField(max_length = 50)
    ...

我以这种方式保存对象:

new_demographic = Demographic(
            status = smart_unicode(my_dict[i]['status']),
            region = smart_unicode(my_dict[i]['network']),
            ...
        )            
        new_demographic.save()

我也尝试过使用unicode()encode('utf-8')方法,但遗憾的是,它们也没有效果。谁能帮我解决这个问题?

这是完整的回溯:

如果您使用 @python_2_unicode_compatible,那么您的 __str__ 方法应该 return 一个 unicode 字符串。

你有 str(self.region+", "+self.country),它试图在 Python 中将 unicode 字符串转换为字节字符串 2. 要解决此问题,请将方法更改为:

def __str__(self):
    return self.region + u"," + self.country
