Django 管理员尝试将 CharField 编码为 "ascii"

Question

我知道这个问题已经被问过很多次了，但我读了那些 zillon 的答案，但没有解决这个特定问题的任何有用信息。

这是我的问题的最小模型示例：

错误不在 CharField 上，而是在保存相关文件（同名文件）时。我误解了原来的错误。谢谢大家的热心帮助:)

我正在使用 python 2.7、django 1.7 和 postgres 作为数据库后端。当我尝试将单词 "Resúmenes" 保存为模型 "titulo" 时，我得到了邪恶的

Exception Value:'ascii' codec can't encode character u'\xfa'...

我知道 django 默认是使用 UTF-8（它在许多其他模型中也是这样工作的）并且我没有更改任何相关内容。我验证了数据库也在 DB/tables/columns.

使用 UTF-8

有什么提示吗？

编辑：我正在使用 Django admin 创建对象。完整的回溯是这个：

Exception Type: UnicodeEncodeError at /admin/resumenes/resumen/add/
Exception Value: 'ascii' codec can't encode character u'\xfa' in position 67: ordinal not in range(128)

Answer 1

这应该有效，将此方法添加到您的模型中，并删除您原来的 Unicode 方法。

def __str__(self):
  return self.titulo

Answer 2

您的回溯与您的模型定义不匹配。回溯显示你在某处有一个 FileField。

无论如何，建议您检查您的系统区域设置并确保它设置为 UTF-8。
