Github actions for django app migrations checker. To fix multiple develop commit django migration in different Pull Request at the same time, and then cause conflict migration issue.

Use python package django-migration-checker to do migration validation. The package will not install any django related package. Check migration by read file, not python import. So may not perfect solution, but good enough.

Workflow example:

name: Django Migration Checker
on: pull_request

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout the latest code
        uses: actions/checkout@v2
        with:
          fetch-depth: 1

      - name: Django Migration Checker
        uses: hardcoretech/django-migration-checker-action@v2
        with:
          app-path: app
          docker-image-tag: 0.8.0

inputs

• app-path: django app folder path. after action/checkout, the working dir would be repository root.
  • default: app
• docker-image: docker image name. you are able to change the image hub to private source.
  • default: hardcoretech/django-migration-checker
• docker-image-tag docker image tag, it should represent version of django-migration-checker (python package)
  • default: latest

Why do we need to maintain docker image rather than build it directly in github action?

• Provide the capability for CI environment to use the image to do the checking as well.

If django-migration-checker package upgraded, need to update and push docker image. Doesn't need to release new github action version. And the version should match with python package version.

• make push-to-aws-ecr DMC_VERSION=<new version> IMAGE_TAG=<new version> AWS_ACCOUNT_ID=<aws account id>
• make push-to-docker-hub DMC_VERSION=<new version> IMAGE_TAG=<new version>

Only upgrade the version of github action when you change the content of action.yml.

• Docker Hub - django-migration-checker
• Github - python package - django-migration-checker
