Django admin 的 auth 部分中没有用户链接

Question

I am trying to implement a custom user model, but under the auth url localhost:8000/admin/auth/ of the Django admin website my model is not showing up.

I found an answer at the link below to the overall problem, but when trying to implement it myself I still do not see the users in the auth section of the Django admin.

No “Users” link in “Auth” section of Django admin site

what am I doing wrong here ?

models.py

from django.contrib.auth.models import AbstractUser


class CustomUser(AbstractUser):
    pass

admin.py

from django.contrib import admin
from django.contrib.auth import get_user_model
from django.contrib.auth.admin import UserAdmin
from .forms import CustomUserCreationForm, CustomUserChangeForm

CustomUser = get_user_model()


class CustomUserAdmin(UserAdmin):
    form = CustomUserChangeForm
    add_form = CustomUserCreationForm
    model = CustomUser
    list_display = (
        "email",
        "username",
    )

    fieldsets = (
        (None, {"fields": ("email", "password")}),
        ("Permissions", {"fields": ("is_admin", "groups", "user_permissions")}),
    )


admin.site.register(CustomUser, CustomUserAdmin)

forms.py

from django.contrib.auth import get_user_model
from django.contrib.auth.forms import UserCreationForm, UserChangeForm


class CustomUserCreationForm(UserCreationForm):
    class Meta:
        model = get_user_model()
        fields = ("email", "username")


class CustomUserChangeForm(UserChangeForm):
    class Meta:
        model = get_user_model()
        fields = ("email", "username")

Answer 1

I faced the same problem:

1. created my own user model
2. in admin, groups and my user model are not listed in same (auth) section

My solution was basically to put django groups into my app to have it displayed in the same section, because django creates admin sections for each app.

1. create your own group model as proxy object in your models.py

from django.contrib.auth.models import Group as DjangoGroup

...

class Group(DjangoGroup):
    class Meta:
        proxy = True
        verbose_name = _('group')
        verbose_name_plural = _('groups')

2. (un)register your models in admin.py

from django.contrib.auth.admin import GroupAdmin as DjangoGroupAdmin
from django.contrib.auth.models import Group as DjangoGroup
from .models import CustomUser, Group

...

admin.site.register(CustomUser, CustomUserAdmin)

admin.site.unregister(DjangoGroup)
admin.site.register(Group, DjangoGroupAdmin)
