Django Admin Kink with Collapse Fieldsets

我无法在管理控件中显示 collapse fieldset . 最重要的是，每当我进入管理控件时，我偶尔也会出现加载错误，这似乎只是出现 . 我无法将错误拼凑起来推测导致问题的原因，但是当我在 admin.py 中包含所包含的代码时，我似乎只能重现它 .

管理员布局错误

admin.py

from forum.models import Category, Thread, Post
from django.contrib import admin

class PostAdmin(admin.ModelAdmin):
  fieldsets = [
    (None, {'fields': ['author']}),
    (None, {'fields': ['thread']}),
    (None, {'fields': ['creation_date']}),
    (None, {'fields': ['content'], 'classes': ['collapse']}),
    (None, {'fields': ['is_removed']}),
    (None, {'fields': ['agrees'], 'classes': ['collapse']}),
    (None, {'fields': ['thanks'], 'classes': ['collapse']}),
    (None, {'fields': ['saves'], 'classes': ['collapse']}),
  ]

  admin.site.register(Post, PostAdmin)

（偶然）错误

可能导致这种情况的任何想法？

EDIT: 仔细检查后，即使折叠的字段被注释掉，错误仍然存在 . 布局问题可能与此错误有关或完全分开 . 显然，我希望看到两者都是固定的 .

这是看似不同的错误：
