django 1.9: ProgrammingError: relation "users_user" does not exist
django 1.9: ProgrammingError: relation "users_user" does not exist
我在执行迁移时 运行 遇到 ProgrammingError，我认为这可能与自定义用户使用 django-allauth 有关。这是我做的
1/ 使用 psql 创建一个新的数据库：
create database dj_example;
2/Installed_apps包含django.contrib.sites:
DJANGO_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
'django.contrib.staticfiles',
'django.contrib.admin',
)
THIRD_PARTY_APPS = (
'crispy_forms', # Form layouts
'allauth', # registration
'allauth.account', # registration
#'allauth.socialaccount', # registration
#'allauth.socialaccount.providers.twitter',
'djcelery', #Celery
)
LOCAL_APPS = (
'tucat.users', # custom users app
}
3/site_id设置为1
SITE_ID = 1
4/自定义用户模型过于简单：
# -*- coding: utf-8 -*-
from __future__ import unicode_literals, absolute_import
from django.contrib.auth.models import AbstractUser
class User(AbstractUser):
def __unicode__(self):
return self.username
5/ Makemigrations 工作正常
# python manage.py makemigrations
Migrations for 'djcelery':
0028_auto_20160601_1919.py:
- Alter field status on taskmeta
6/ 迁移 returns ProgrammingError: 关系 "users_user" 不存在
# python manage.py migrate
Operations to perform:
Apply all migrations: auth, contenttypes, djcelery, account, admin, sessions
Running migrations:

知道如何解决这个问题吗？
您的错误是由 运行 迁移的顺序引起的。由于许多应用程序依赖于现有的用户模型，因此您必须 运行 在其他应用程序之前为您的自定义用户应用程序进行初始迁移。
如果您更改现有项目中的默认用户模型，放弃所有现有迁移（和数据库）并从头开始重建可能更容易。应用迁移的顺序为：
- 核心
django.contrib 个应用程序。
- 您的自定义用户应用。
- 其他自定义应用和第三方应用。
您可以使用 django-admin showmigrations 查看存在和计划中的迁移。
您必须删除迁移文件夹，然后，您应该这样做
python manage.py migrate --run-syncdb
python manage.py migrate --fake appname
仅供参考-
我遇到了这个问题，为了解决它，我不得不在我的 urls.py 和 url_tenants.py 文件中注释掉所有对 views.py 的引用。然后，我 运行 makemigrations 并创建要创建的数据库表，然后 运行 migrate_schemas，然后取消注释 url 文件。希望这对某人有所帮助。
