Django 管理员与折叠字段集的纠结

标签 django django-admin

我无法在管理控件中显示 collapse 字段集。最重要的是，我还会时不时地收到加载错误，该错误似乎只在我处于管理控件中时才会出现。我无法将错误拼凑在一起来推测导致问题的原因，但当我将包含的代码包含在 admin.py 中时，我似乎只能重现它。

管理布局错误

Admin layout error

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)

(偶尔)错误

有什么想法可能导致这种情况吗？

编辑:经过仔细检查，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独立。显然，我希望看到这两个问题都得到解决。

这是看似不同的错误:

相关问题

  1. Django runserver error
  2. Error on display static content

最佳答案

问题是这行(和类似的):

(None, {'fields': ['agrees'], 'classes': ['collapse']}),

当字段集标题为None时，没有字段集标题，因此无需单击即可展开字段集。 This comment在 Django 错误跟踪器中，虽然很旧，但表明不使用标题和 collapse 是一个坏主意 (tm)，你“只是不应该这样做。”

至于您的其他问题，您的操作系统存在某种形式的问题。它只是意味着已建立连接(到您的 Python 服务器)，但您的计算机(您的主机)由于某种原因在 Python 完成连接之前终止了连接。

这个问题有点老了，但它在“django fieldset crash does not work”这样的搜索结果中仍然相当高，所以我想我可能会为 future 的搜索者回答这个问题。
