Question

Django migrations are not applied to postgres database

I followed the following documentation https://docs.digitalocean.com/tutorials/app-deploy-django-app/

My app has deployed fine however when I push changes that require me to run python manage.py makemigrations and python manage.py migrate I see the following…

after makemigrations i see the changes migrations being made

but when I run migrations it says there are no migrations…

Basically the posgres database does not update and I have to delete the database after every migration…

Hello,

Do you have an additional App component for running your Django migration?

You could add the following to your app yaml file:

jobs:
- name: migrate
  kind: PRE_DEPLOY
  github:
    repo: digitalocean/sample-django
    branch: static
    deploy_on_push: true
  run_command: python manage.py migrate
  envs:
  - key: DISABLE_COLLECTSTATIC
    value: "1"
    scope: BUILD_TIME
  - key: DATABASE_URL
    value: "${db.DATABASE_URL}"
    scope: RUN_TIME

For a reference, here is an example yaml file that contains all of the required components:

Let me know how it goes!

Best,

Bobby
