Question

我正在尝试将heroku上托管的djnago应用程序连接到mongodb地图集。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，出现了错误。

我什至尝试从Settings.py中删除DATABASE字典

我可以通过更改settings.py中的这一行来解决该问题

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

收件人：

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

从heroku上托管的Django应用程序连接到Mongodb
