Question

我正在尝试使用django应用程序在Heroku上工作。

我一直收到这个错误：

Running `./manage.py migrate` attached to terminal... up, run.5743
Traceback (most recent call last):

    DATABASES['default'] =  dj_database_url.config()
NameError: name 'DATABASES' is not defined

以下是settings/base.py中的设置。在制作中，我将DJANGO_SETTINGS_MODULE设置为settings/dev.py，但没有任何数据库配置（安全问题在这里并不重要。我只是部署，所以其他人可以看看他们可能想要使用的CMS。）

Answer 1

DATABASES未定义，因此请尝试相反设置，而不是更新它。将该行更改为：

DATABASES = { 'default': dj_database_url.config() }

Heroku'DATABASES'没有定义
