【问题描述】：

我正在尝试将托管在 heroku 上的 djnago 应用程序连接到 mongodb atlas。我还将 heroku 设置上的 DATABASE_URL 更改为：

mongodb+srv://<name>:<password>@cluster0.wtnph.mongodb.net/test

我正在使用 python 3.9 和 django 3.0.5 但是当部署到heroku时，我得到了错误。

我什至尝试从 Settings.py 中删除 DATABASE dict

我可以通过更改 settings.py 中的这一行来解决问题

发件人：

# Activate Django-Heroku.
django_heroku.settings(locals()),

收件人：

# Activate Django-Heroku.
django_heroku.settings(locals(), databases=False),
