django manage.py提出错误配置错误

Question

在尝试运行./manage.py runserver或shell或任何其他命令时,我收到错误:您必须定义一个"默认"数据库.

我在virtualenv中运行它,settings.py包括DATABASE_NAME,以及主机,端口和引擎.django在哪里期待默认数据库的定义？

这是追溯:

django.core.exceptions.ImproperlyConfigured: You must define a 'default' database

Answer 1

自django 1.2以来,DATABASE_NAME已弃用,因此如果您使用的是较新版本,则应使用新的定义数据库的方式:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': 'mydatabase'
    }
}
