我尝试用MySQL设置Django，但发生了UnicodeDecodeError。 你能让我知道如何解决这个问题吗？我搜索了错误，但我无法理解。
我找到了这些代码并试过了，
def __unicode__(self):
return str(self.id) + ':' + self.name
和
def __str__(self):
return self.name.encode('utf8')
但我无法解决问题可能是因为我不知道如何使用def unicode （）而这些不适合我的列。
这是命令。

当我使用centOS6时，我没有这种错误，尽管这些软件的版本不同。 如果您向我推荐一些解决方案或建议，我们将不胜感激。 谢谢。
PS。我是这个网站的新手，所以我不知道如何在这里正确询问。对不起。
