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无数次了，但是我读了这些问题的答案，没有任何东西对解决这个问题有用。在

这是我的问题的一个最小模型示例：

---

错误不在字符域上，而是在保存相关文件（同名）时发生的。我误解了原来的错误。感谢大家的帮助：）

---

我使用python2.7、django1.7和postgres作为数据库后端。当我试图把“Resúmenes”这个词保存为“titulo”的模型时，我得到了nepharious

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都是这样工作的），而且我没有更改任何相关的内容。我验证了DB对DB/tables/columns也使用了UTF-8。在

有什么线索吗？在

编辑：我使用Django admin创建对象。完整的回溯是这样的：

Answer 1

您的回溯与模型定义不匹配。回溯显示您在某处有一个FileField。在

在任何情况下，建议您检查系统区域设置，并确保将其设置为UTF-8。在

另请参见：

• I’m getting a UnicodeDecodeError. What am I doing wrong?在Django文档中。在
• Python os.stat and unicode file names

Answer 2

这样就可以了，将这个方法添加到模型中，并去掉原来的Unicode方法。在
