django deploy to Heroku : Server Error(500)

Question

I am trying to deploy my app to heroku.
Deploy was done correctly but I got Server Error(500).
When I turned DEBUG true, Sever Error doesn't occurred.
So I think there is something wrong with loading staticfiles.

I can't find any notable, critical error in log.
I have already installed whitenoise, but it doesn't work.

Is there anyone who solves this problem?

Answer 1

This doesn't have anything to do with whitenoise. The problem is your ALLOWED_HOSTS setting; this needs to have the hostname of your site.

Answer 2

I had the same Problem even when my ALLOWED_HOST settings were correct and DEBUGING = False

But what cause mine was that i did not make migration on my herokuapp after deploying. I solved it by typing

heroku run bash

then make migrations with `

python manage.py migrate

Answer 3

Your database may not be in sync. This might happen after you reset database. Run

python manage.py migrate --run-syncdb

to sync the database.
