Open Learning Django Apps

This repository is the home of MIT Open Learning's reusable django apps

Changelogs

We maintain changelogs in changelog.d/ directories with each app. To create a new changelog for your changes, run:

• mkdir ./src/mitol/{APPNAME}/changelog.d
• rye run build changelog create --app APPNAME
  • APPNAME: the name of an application directory

Then fill out the new file that was generated with information about your changes. These changes will all be merged down into CHANGELOG.md when a release is generated.

Releases

Changelogs are maintained according to Keep a Changelog. Versioning uses a date-based versioning scheme with incremental builds on the same day. Version tags follow {package-name}/v{version} To perform a release, run:

• rye run build release create --app APPNAME --push:
  • APPNAME: the name of an application directory

Navigating this repository

• Django applications follow the naming convention mitol-django-{name}, pip installable by the same name.
• Within each app, code is implemented under the implicit namespace mitol
  • Module paths follow the pattern mitol.{name}
  • The app itself is installable to INSTALLED_APPS as "{name}".

Prerequisites

Use the docker-compose container (recommended)

• You'll need to make sure other users (the docker container user), can write to the repo root directory. Run chmod o+w .
• Run docker compose run --rm shell bash to get a clean sandbox environment

Use on your host system

• Install xmlsec native libraries for your OS: https://xmlsec.readthedocs.io/en/stable/install.html
• Install rye following the instructions at https://rye.astral.sh/

Usage

We use rye to manage apps and releases.

Useful commands:

# run all tests
rye test
# run only common app tests
rye test -p mitol-django-common

# build a package
rye build -p mitol-django-common

# format code (isort + black)
rye fmt

# run lints
rye lint

# run django management scripts
rye run tests/manage.py -- ARGS
# run a django shell
rye run tests/manage.py -- shell
# create migrations
rye run tests/manage.py -- makemigrations
# run a django migrate
rye run tests/manage.py -- migrate

Migrations

To generate migrations for a reusable app, run the standard:

rye run tests/manage.py -- makemigrations APP_NAME --name MIGRATION_NAME

where APP_NAME matches the name attribute from your apps.py app.

Adding a new app

• Create the project:

NAME="[APP-NAME]"
mkdir src/mitol/$NAME
pants run :django-admin -- startapp $NAME src/mitol/$NAME

• Add a BUILD file, following using the same files from other projects as a guideline
• Add the project as a dependency in src/BUILD
• Add the project to the testapp
  • Add the project app in tests/testapp/settings/shared.py under INSTALLED_APPS
