Question

在测试服务器中，它正在运行。但是生产给出了这个追溯：有什么不同？这个错误意味着什么？

不同之处仅在于python版本。在测试服务器中，它是2.6.5和生产2.5.2。如何在不更改版本的情况下摆脱此错误？

经过一段时间的思考和测试。我注意到错误仅在我这样做时显示：

med,created=RemMedia.objects.get_or_create(index=program.Id+50000000, defaults=fields)

经过一段时间的思考结束测试后，我发现了错误。它在字典fields中。我从BeautifulSoup获得了一个变量，代码如下：

                        soup=BeautifulSoup(program.Description.encode('utf-8'))
                        name=soup.find('div',{'class':'head'})
                        fields=dict(
                               name=name.string,
                               description=program.Description.encode('utf-8'),
                               program_name=program.Name.encode('utf-8'),
                               program_date_time=program.RealDateTime,
                               topic_data_time=program.RealDateTime,
                               topic_tag='',
                               created=program.Updated,
                               media=media
                                     )

问题在于name词典中的变量fields。

问题仍然存在：如何转换它以免出错？

UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-10: ordinal not in range(128)

你有一个ascii值＆gt;的角色吗？ 128？可能是重音字母。

Answer 2

如果问题出在数据库中，那可能就是一个设置。如果它在python代码中，您可以尝试将此行放在python文件的顶部以处理字符串。

# coding:utf-8

有趣的情况。数据库错误？蟒蛇。 Django的
