您可以检查项目repo链接：github.com/osamamhd/ivyTasks

Answer 1

首先，将Heroku生成的url添加到settings.py中的ALLOWED_HOSTS

然后将gunicorn添加到requirements.txt以确保heroku为您下载包

最后，在项目根目录中添加一个名为Procfile的文件（与manage.py路径相同），其中包含以下内容：

web: gunicorn ivytasks_project.wsgi log-file -

然后在概览选项卡中的heroku仪表板中向下滚动到Dyno Formation，并在工作程序关闭时启用它
