南+ Django 1.4数据库错误 [英] South + Django 1.4 Database error

问题描述

我刚刚在新系统上安装了Django项目，并安装了Django 1.4。但是，当我尝试运行 manage.py runserver 或 manage.py syncdb 我从南部得到这个错误： p>

我是目前使用SQlite。我认为这可能是因为这个更改与Django 1.4，但其他用户似乎没有我的问题。我的所有包都是最新的。

解决方案

你没有正确的设置中的djangoproject.com/en/1.4/ref/settings/#databasesrel =noreferrer> DATABASES 。应该有一个数据库名为'default'

I have just installed my Django project on a new system, and installed Django 1.4. However when I try to run manage.py runserver or manage.py syncdb I get this error from South:

    db = dbs[DEFAULT_DB_ALIAS]
KeyError: 'default'

I am using SQlite currently. I think it might be because of this change with Django 1.4, however other users don't seem to having my problem. All my packages are up to date.

解决方案

You don't have correct DATABASES in your settings. There should be a database named 'default'
