使用对 github repo 的新提交更新 heroku django 部署的站点

Question

Say I have deployed a django website on heroku through a github repository. (For deployment I simply clicked on the deploy button here - https://github.com/AmmsA/theresumator#theresumator---using-django-resumator .) I now update the repository with new commits.

Q: How can I make changes in the deployed website from the repository without losing the data already present on the repository.

Answer 1

When you are pushing the fresh commits git push heroku master or via git hook git push origin master -- these nothing to do with heroku database.

But this will run this command when build python manage.py migrate so if you are changed something in the migrations definetly db schema get alter not the values stored in there.

Answer 2

Just set your remote project:

heroku git:remote -a

And then, push your project on Heroku: git push heroku main

I've written an article on it. You can see that. https://medium.com/@sreebash/how-to-update-previous-deployed-project-on-heroku-c778d555cd8a
