Question

我刚开始我的新django 1.8项目。我创建了一个超级用户并转到127.0.0.1:8000/admin/并从中登录。登录后，它显示以下错误：

(1054, "Unknown column 'django_content_type.name' in 'field list'")

我四处搜索，发现了一个相关的问题，here。

正如在那里的讨论中所说，我放弃了我的架构并重新创建了很多次;我仍然得到同样的错误。我的数据库中的django_content_type表只有三个字段：id，app_label和model。它没有弃用的“名称”。

此外，我可以访问其他网址，例如/admin/auth/，/admin/auth/users/，但尝试添加更多用户会产生以下错误（我认为这也是由于与上述问题相同）：< / p>

Error creating new content types. Please make sure contenttypes is migrated before trying to migrate apps individually.

总的来说，我对Django很新。任何帮助将非常感激。感谢。

这是完整的错误：

OperationalError at /admin/

    Request Method: GET

我意识到这个错误显示我的django版本为1.7，而我使用pip安装了django 1.8。我跑了python manage.py shell并从那里检查了我的django版本（无法发布截图，代表不够高）。

$ python manage.py shell
>>> import django
>>> django.VERSION
(1, 8, 2, 'final', 0)
>>>

我该如何纠正？再次感谢。我正在使用virtualenv。

修改：添加urls.py

"""rmgl_project URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
https://docs.djangoproject.com/en/1.8/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  url(r'^$', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  url(r'^$', Home.as_view(), name='home')
Including another URLconf
    1. Add an import:  from blog import urls as blog_urls
    2. Add a URL to urlpatterns:  url(r'^blog/', include(blog_urls))
"""
from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
]

添加manage.py：

#!/usr/bin/env python
import os
import sys

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE",     "rmgl_project.settings")

    from django.core.management import execute_from_command_line

    execute_from_command_line(sys.argv)

问题在于virtualenv - 它没有启用。

为了检查Django的版本（以及模块的路径），您可以将以下行添加到./manage.py文件中：

print(__import__('django')) # Should print the module information
print(__import__('django').__file__) # Should print the location of __init__.py file

在if __name__ == '__main__'行之后。
