由于唯一键约束，我收到完整性错误，并且我不想从那里删除唯一约束。
我尝试了python manage.py flush并再次进行迁移，但仍然无法正常工作。
在那里最需要唯一约束，因为它将作为唯一用户名传递给用户。
代码如下
test.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='tatanano@nano.com',
password='password1234'
)
self.client.force_login(self.admin_user)
self.user = get_user_model().objects.create_user(
email='tatanano@nano.com',
password='password1234',
name='test user full name'
)
def test_users_listed(self):
"""Test user that 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)
models.py
from django.db import models
from django.contrib.auth.models import AbstractBaseUser, BaseUserManager, \

user.set_password(password)
user.save(using=self._db)
return user
def create_superuser(self, email, password):

user.is_staff = True

return user
