尝试通过django默认基于文件的后端保存文件的UnicodeDecodeError

Question

当我尝试通过默认的instance.file_field.save方法将名称中包含俄语符号的文件添加到模型实例时,我得到一个UnicodeDecodeError(ascii解码错误,不在存储后端的范围(128)中(堆栈跟踪在os上结束).如果我通过默认的python文件写这个文件open/write all right.所有文件名都在utf-8.我只在测试Gentoo时得到这个错误,在我的Ubuntu工作站上一切正常.

class Article(models.Model):
    file = models.FileField(null=True, blank=True, max_length = 300,
                            upload_to='articles_files/%Y/%m/%d/')

Traceback:

Answer 1

解决方案非常简单：

在修订版 12659 中，此错误已得到修复。 http://code.djangoproject.com/ticket/11030

但修订版 12661 恢复了它

“（在 [12661] 中）修复了#11030：恢复了假设文件系统编码为 utf8 的更改，并更改了测试以演示该假设如何在不使用 utf8 作为文件的系统上损坏上传的非 ASCII 文件名系统编码（特别是 Windows）。感谢 vrehak 的报告。”

所以我需要做的就是恢复到12659
