管理中的 DjangoUnicodeDecodeError 与 DEBUG=False

Question

我对 Django 管理有一点奇怪的问题。在 settings.py 中使用 DEBUG=True，一切正常。但是当我将其更改为 DEBUG=False 时，我无法进入项目的页面编辑。我收到此错误:

DjangoUnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 0: ordinal not in range(128). You passed in <django.forms.forms.BoundField object at 0x327bd90> (<class 'django.forms.forms.BoundField'>)

我不知道，为什么我只用 DEBUG=False 得到它。

Answer 1

我有它;)

在 admin.py 中，我有自己的 MultipleChoiceField 表单:

people = forms.ModelMultipleChoiceField(
    Person.objects.all(),
    widget=FilteredSelectMultiple("Účastníci", False, attrs={'rows': '10'})
)

class Meta:
    model = Event

即使我有

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

在文件的开头，“Účastníci”制造了麻烦。当我将其更改为“Ucastnici”时，一切正常。
