【问题描述】：

我在用户管理员中有一个用户列表，其中有一个名为域（电子邮件域）的列，现在当用户使用他的邮件 id 登录时，他应该只能看到他的域的用户，而不是其他域的用户。例如，如果 sourabh@gmail.com 正在登录，那么只有 gmail 用户应该可见。

admin.py

from .models import User
from django.contrib import admin
from django.contrib.auth.admin import UserAdmin as BaseUserAdmin

class UserAdmin(BaseUserAdmin):

    list_display = ('email', 'domain','admin', 'is_active', 'is_staff')
    list_filter = ('admin', 'is_staff', 'is_active', 'groups', 'domain')
    fieldsets = (
        (None, {'fields': ('email', 'password', 'domain')}),
        ('Permissions',{ 'fields': (
            'is_active', 
            'is_staff', 
            'is_superuser', 
        )}),
    )

    add_fieldsets = (
        (None, {
            'classes': ('wide',),
            'fields': ('email', 'password1', 'password2')}
        ),
    )
    search_fields = ('email',)
    ordering = ('email',)
    filter_horizontal = ()


admin.site.register(User, UserAdmin)

models.py

from django.contrib.auth.models import BaseUserManager, AbstractBaseUser, PermissionsMixin
from django.db import models


class MyUserManager(BaseUserManager):

    def _create_user(self, email, password, domain, is_staff, is_superuser, **extra_fields):
        if not email:
            raise ValueError('Users must have an email address')
        email = self.normalize_email(email)
        user = self.model(
            email=email,
            domain = domain,
            is_staff=is_staff, 
            is_active=True,
            is_superuser=is_superuser,

        user.set_password(password)

        user.save(using=self._db)
        return user


class User(AbstractBaseUser, PermissionsMixin):

    email = models.EmailField(max_length=254, unique=True)
    name = models.CharField(max_length=254, null=True, blank=True)
    is_staff = models.BooleanField(default=True)
    is_superuser = models.BooleanField(default=False)
    is_active = models.BooleanField(default=True)
    domain = models.CharField(max_length=254)

    USERNAME_FIELD = 'email'
    EMAIL_FIELD = 'email'

    admin = models.BooleanField(default=False) # a superuser

    objects = MyUserManager()

    def __str__(self):
        return self.email

【解决方案1】：

这实际上在the admin documentation 中明确涵盖；你应该覆盖get_queryset。

class UserAdmin(BaseUserAdmin):
    ...
    def get_queryset(self, request):
        qs = super().get_queryset(request)
        if request.user.is_superuser:
            return qs
        return qs.filter(domain=request.user.domain)
