Unable to log in to Django admin panel after Railway deployment

Time：12-17

I'm new to Django, and even newer to using Railway so please be kind. I've got a portfolio project that uses Django on the back end, and I was previously hosting on Heroku. I've attempted to move the deployment to Railway, and I've encountered a problem I can't figure out. Locally, I'm able to sign into the Django admin panel with the superuser credentials. When I attempt the same on the Railway deployment, I get a really long error that doesn't point to anything in my code. I've tried to research the error for a few days now, and I'm coming up blank. I honestly don't even have a direction to look for a solution. This is the error I see when I attempt to sign into the admin panel: (Happy to add other files, but I don't know what is relevant?)

I've tried making changes to environment variables, also tried railway run python3 manage.py createsuperuser but it will tell me the superuser already exists. I just don't know where the error is coming from so I don't know where to look?

CodePudding user response：

the error says that there is no connection to the database. It is working locally because you have installed postgresql locally. Have you installed a postgres on railway and what is the host of the database ? Django settings needs to know the host name of the database. Btw try to create different environment settings (local => dev and prod).
