未定义配置，在heroku中部署

Question

我正在尝试在heroku上部署我的django应用程序，我也想在heroku上使用remote postgre。dj-database-url是在我的需求文件中定义的，我也在setting.py中导入了该文件。

requirements.txt

dj-database-url
gunicorn
Babel==2.6.0





settings.py

import dj_database_url
DATABASES = {

    'default': dj_database_url.config(
        default=config('DATABASE_URL')
    )
}

在部署时，我遇到了下面的错误，这里有什么遗漏的地方吗？

"NameError: name 'config' is not defined"

 !     Error while running '$ python manage.py collectstatic --noinput'.
       See traceback above for details.
       You may need to update application code to resolve this error.
       Or, you can disable collectstatic for this application:
          $ heroku config:set DISABLE_COLLECTSTATIC=1
