总是得到这个 AssertionError: 302 != 200 : 无法检索内容：响应代码是 302 (预期 200)

Question

我是 django 的新手，目前正在学习教程，我试图测试用户是否列在用户页面上。 所以我设置了 test_admin.py。 我得到一个 AssertionError 302 != 200。

下面是我的 test_admin.py

from django.test import TestCase,Client
from django.contrib.auth import get_user_model
from django.urls import reverse


class AdminSiteTests(TestCase):

    def setUp(self):
        self.client = Client()
        self.admin_user = get_user_model().objects.create_superuser(
            email='admin@gmail.com',
            password='092100027h'
        )
        self.client.force_login(self.admin_user)
        self.user = get_user_model().objects.create_user(
            email='test@gmail.com',
            password='092100027h',
            name='Test User Full Name'
        )

    def test_users_listed(self):
        """
        Test that users are listed on user page
        """
        url = reverse('admin:core_user_changelist')
        res = self.client.get(url)

        self.assertContains(res, self.user.name)
        self.assertContains(res, self.user.email)

这是我的 admin.py

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

from . import models

class UserAdmin(BaseUserAdmin):
    ordering = ['id']
    list_display = ['email', 'name']


admin.site.register(models.User, UserAdmin)

这是我的错误

Answer 1

该问题可能与APPEND_SLASH Django 设置有关。 默认情况下它的True 。 因此，请检查您的 urls 文件并确保此 url 以斜杠/结尾（例如articles/<int:year>/否则 Django 将找不到该 url 并会自动添加斜杠并将您重定向到新的 url，您将收到302状态码为重定向。

Answer 2

是我的错，我不小心把is_active的默认设置成了False，应该是这样的

class User(AbstractBaseUser, PermissionsMixin):
    """Custom user model that support using email instead of username"""
    email = models.EmailField(max_length=255, unique=True)
    name = models.CharField(max_length=255)
    is_active = models.BooleanField(default=True) <<< This one
    is_staff = models.BooleanField(default=False)
