/ admin / login /处的OperationalError没有这样的表：auth_user

Question

即使多次运行syncdb后，我仍收到此错误，并且我正在使用Django 1.7.4

而且我也尝试过手动迁移已安装的应用程序，但仍然不能解决问题。

环境：

Request Method: POST
Request URL: https://myapp.herokuapp.com/admin/login/?next=/admin/

Django Version: 1.7.4
Python Version: 2.7.12
Installed Applications:
('django.contrib.admin',
 'django.contrib.auth',
 'django.contrib.contenttypes',
 'django.contrib.sessions',
 'django.contrib.messages',
 'django.contrib.staticfiles',
 'core')
Installed Middleware:
('django.contrib.sessions.middleware.SessionMiddleware',
 'django.middleware.common.CommonMiddleware',
 'django.middleware.csrf.CsrfViewMiddleware',
 'django.contrib.auth.middleware.AuthenticationMiddleware',
 'django.contrib.auth.middleware.SessionAuthenticationMiddleware',

Answer 1

如果您只是Django的新手，我建议您使用Django1.8 +或更高版本。

1. 首先，检查配置是否正确设置。

   $ python manage.py check

2. 然后，您应该进行迁移

   $ python manage.py makemigrations

3. 映射数据库

   $ python manage.py migrate
