django-pony-express

Welcome to the django-pony-express - class-based emails for Django shipping with a full test suite.

Similar to class-based view in Django core, this package provides a neat, DRY and testable (!) way to handle your emails in Django.

• PyPI
• GitHub
• Full documentation
• Creator & Maintainer: Ambient Digital

Features

• Class-based structure for emails
  • Avoid duplicate low-level setup
  • Utilise inheritance and OOP benefits
  • No duplicated templates for HTML and plain-text
• Test suite to write proper unit-tests for your emails
  • Access your test outbox like a Django queryset

Etymology

The Pony Express was an American express mail service that used relays of horse-mounted riders. [...] During its 18 months of operation, the Pony Express reduced the time for messages to travel between the east and west US coast to about 10 days.

https://en.wikipedia.org/wiki/Pony_Express

The name of this package combines the Django mascot (a pony) with a once quite successful mail service in the US. Ingenious, right?

• Install "pip-tools" with pip install -U pip-tools
• Compile the requirements with pip-compile --extra dev, -o requirements.txt pyproject.toml --resolver=backtracking
• Sync the dependencies with your virtualenv with pip-sync

Add functionality

• Create a new branch for your feature
• Change the dependency in your requirements.txt to a local (editable) one that points to your local file system: -e /Users/workspace/django-pony-express or via pip pip install -e /Users/workspace/django-pony-express
• Ensure the code passes the tests
• Create a pull request

Run tests

• Run tests

  pytest --ds settings tests
  

• Check coverage

  coverage run -m pytest --ds settings tests
  coverage report -m
  

Git hooks (via pre-commit)

We use pre-push hooks to ensure that only linted code reaches our remote repository and pipelines aren't triggered in vain.

To enable the configured pre-push hooks, you need to install pre-commit and run once:

pre-commit install -t pre-push -t pre-commit --install-hooks

This will permanently install the git hooks for both, frontend and backend, in your local .git/hooks folder. The hooks are configured in the .pre-commit-config.yaml.

You can check whether hooks work as intended using the run command:

pre-commit run [hook-id] [options]

Example: run single hook

pre-commit run ruff --all-files --hook-stage push

Example: run all hooks of pre-push stage

pre-commit run --all-files --hook-stage push

Update documentation

• To build the documentation, run: sphinx-build docs/ docs/_build/html/.
• Open docs/_build/html/index.html to see the documentation.

Translation files

If you have added custom text, make sure to wrap it in _() where _ is gettext_lazy (from django.utils.translation import gettext_lazy as _).

How to create translation file:

• Navigate to django-pony-express
• python manage.py makemessages -l de
• Have a look at the new/changed files within django_pony_express/locale

How to compile translation files:

• Navigate to django-pony-express
• python manage.py compilemessages
• Have a look at the new/changed files within django_pony_express/locale

Publish to ReadTheDocs.io

• Fetch the latest changes in GitHub mirror and push them
• Trigger new build at ReadTheDocs.io (follow instructions in admin panel at RTD) if the GitHub webhook is not yet set up.

Publish to PyPi

• Update documentation about new/changed functionality

• Update the Changelog

• Increment version in main __init__.py

• Create pull request / merge to master

• This project uses the flit package to publish to PyPI. Thus publishing should be as easy as running:

  flit publish
  

  To publish to TestPyPI use the following ensure that you have set up your .pypirc as shown here and use the following command:

  flit publish --repository testpypi
  

Maintenance

Please note that this package supports the ambient-package-update. So you don't have to worry about the maintenance of this package. All important configuration and setup files are being rendered by this updater. It works similar to well-known updaters like pyupgrade or django-upgrade.

To run an update, refer to the documentation page of the "ambient-package-update".
