的Django == 1.10.2
尝试在管理视图中使用Group.members相关属性和模型：
from django.utils.translation import ugettext as _
from django.contrib.auth.models import AbstractUser
from django.db import models
class User(AbstractUser):
group = models.ForeignKey(
'Group',
verbose_name=_('Groupe'),
related_name='members',
blank=True,
null=True,
)
class Group(models.Model):
name = models.CharField(
max_length=255,
unique=True,
verbose_name=_('Nom'),
error_messages={
'unique': _('Ce nom est déjà utilisée.'),
},
)
creator = models.ForeignKey(
User,
related_name='created_groups',
blank=False,
null=False,
)
def __str__(self):
return self.name
管理员观点：
from django.contrib import admin
from meal.models import Group, User
class GroupAdmin(admin.ModelAdmin):
fields = ('name', 'members')
list_display = ('name', 'members')
search_fields = (
'name',
)
class UserAdmin(admin.ModelAdmin):
fields = ('email', 'last_name', 'first_name', 'group')
list_display = ('email', 'last_name', 'first_name', 'group')
search_fields = (
'username',
'email',
'first_name',
'last_name',
)
admin.site.register(Group, GroupAdmin)
admin.site.register(User, UserAdmin)
但是管理员查看引发错误：
/ admin / meal / group /＆＃39;经理＆＃39;
的KeyError
完成追踪

错误与ForeignKey相关的名称使用有关？如何在管理员中列出修改Group.members（表单）？
答案 0 :(得分：0)
您无法在开箱即用的列表显示中显示相关对象的集合，这甚至会如何工作？
您可以做的是在GroupAdmin类中提供一个方法，并返回可以放入一个更改列表表列的HTML标记（包含members信息），并将该方法包含在{{1 }}
或者您可以在对象（list_display）页面中使用内联。
