Heroku not recognizing migrations

Question

I finally got my Heroku app to work locally at least! However, when I try to open it online it crashes with the following error:

>     2021-10-29T13:16:54.435118+00:00 heroku[web.1]: Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of

I'm not really sure what to make of it but when I ran the app locally it said:

It says I have 20 unapplied migrations, could that be why it doesn't work online? When making migrations then migrating, it just says no migrations to apply.

Most people seem to suggest some change to the Procfile but I don't understand Procfiles well and don't know what to write or why to write it. I didn't find anything which seemed to apply to my app anyway, most of it seems to be about JSON.

Answer 1

First of all make sure that you have the right database settings set in your projects settings,

Most people seem to suggest some change to the Procfile but I don't understand Procfiles

they probabyly suggesting you to add this line to your Procfile

release: python manage.py migrate

for more about Procfile have a look at this

also this question seems really similiar, not quite understood what is your projects flow from the information you have shared but maybe something helps at this question
