在Django Heroku中未连接SQLite数据库

问题描述

因此，我试图将我的项目部署到Heroku，我遵循了以下步骤：https://www.codementor.io/@jamesezechukwu/how-to-deploy-django-app-on-heroku-dtsee04d4 。构建成功，我能够运行服务器：https://pcbuildingparts.herokuapp.com/ 但是数据库似乎无法连接，因为数据库中的项目根本没有显示，因此我尝试在部署之前使用超级用户帐户登录管理站点，但它不允许我进入。这是我的settings.py

解决方法

您为什么要在Heroku上使用SQLite是否有特定原因？一个不错的选择是使用postgress addon并使用SQLite进行本地开发和测试。

查看如何在Django中连接到Postgres：postgres 您还可以使用django-heroku软件包轻松配置django应用。
