Django 管理视图中的用户相关属性

Django==1.10.2

正在尝试将管理员视图中的

组成员
相关属性用于模型：

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

管理员视图：

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)

但是管理员视图引发错误：

位于/admin/mean/group/“manager”的键错误
