I pushed my django backend up, it includes a new app, so some new tables in postgresql and an updated requirements.txt

I thought that when I push to github that railway sees the new migration files and migrates them, but I was wrong. I tried to connect via terminal, using railway link and then railway run python manage.py migrate. That only tried to run migrations locally.

I then used railway up in terminal. It ran my procfile which I added but says it can't see env variables like SECRET_KEY. I have SECRET_KEY and everything else set on railway, so not sure what's happening. Anyway my backend is down, can anybody tell me what I'm missing?

Thanks.
