尝试通过管理员访问数据库时出现此错误
/ admin / nota_app / demographic /
中的UnicodeEncodeError
Exception Type: UnicodeEncodeError
Exception Value: 'ascii' codec can't encode character u'\x8e' in position 0: ordinal not in range(128)
这就是我的模型:
@python_2_unicode_compatible
class Demographic(models.Model):
status = models.CharField(max_length = 100)
region = models.CharField(max_length = 50)
...
我正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()
和encode('utf-8')
方法,但遗憾的是,它们也没有效果。有人可以帮我解决这个问题吗?
这是完整的追溯:

答案 0 :(得分:1)
如果您使用@python_2_unicode_compatible
,那么您的__str__
方法应该返回一个unicode字符串。
你有str(self.region+", "+self.country)
,它试图将unicode字符串转换为Python 2中的字节字符串。要解决此问题,请将方法更改为:
def __str__(self):
return self.region + u"," + self.country
