Question

UnicodeDecodeError模块出现FileAdmin错误（包含在Flask的Flask-Admin库中）：

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe8 in position 5: ordinal not in range(128)

每当我创建一个名称中包含非ASCII字符的目录（例如très）时，我就会收到该错误。

我认为重点是添加UTF-8编码：

# -*- coding: utf-8 -*-

但在哪里（哪些文件？）以及如何在FileAdmin module内处理此问题？我不清楚这一点。

正在发生这种情况，因为当使用ascii路径调用时，Python os.walkdir将返回ASCII中的文件名。

因此，在初始化FileAdmin时，请确保将基本路径作为unicode string ::

传递

admin.add_view(unicode(path), '/files/', name='Files')

最新的Flask-Admin已修复此问题 - FileAdmin将在内部强制执行路径的unicode。
