• A helpful Makefile for faster and easier deployments
• Support for asynchronous task handling with RQ
• Email sending with Sendgrid support
• Build in support for Sentry Error monitoring
• Continuous integration with CircleCI
• Deployment for Heroku with Procfile, app.json, Whitenoise and Foreman
• Docker files of Postgres and Redis for easier local development
• Support of Docker deployments on Heroku
• Code formatting done with Black
• Werkzeug, iPython, django-extensions, django-debug-toolbar and ipdb installed for local debugging

Local setup

Download & install the Docker Community edition

• https://www.docker.com/community-edition

Run the following commands, it will build & start the needed containers (Django, Worker, Postgres DB, Redis, Mailhog):

pipenv install --dev
docker-compose up -d
./manage.py migrate
./manage.py runserver

Open your browser and go to http://localhost:8000/

Deployment

You can deploy project to Heroku using Deploy button or Heroku instructions https://devcenter.heroku.com/categories/working-with-django

Environment variables required to deploy project

Name	What is it?	Default
DATABASE_URL	Database's url	postgresql://${DB_USER}:${DB_PASSWORD}@localhost:${DOCKER_POSTGRES_PORT}/postgres for local, Heroku sets it automatically
REDIS_URL	Redis's url	redis://redis:${DOCKER_REDIS_PORT} for local, Heroku sets it automatically
ENV	App's environment
SECRET_KEY	Secret key that django requires for security	Heroku sets it automatically

All other envs you can find in env.example

Install & Run Locally

This project contains docker integration. You can run it with pipenv run go-docker.

In any case before you need to write your .env file with correct variables: when using the dockerized local development setup, copy .env.local; otherwise copy .env.example to .env, and modifiy accordingly.

Add git hooks

We are using prospectr + pre-commit to make things workable and clear. Before write any code you need to install dev dependencies and run pre-commit install -f after that. Then whenever you run git commit you'll have a fancy output with checks according to our code standards.

Prepare a new branch for your work

Work on new bug/features will be done in a new branch (*) There is a convention in the name of the branches used: 1-short-description-of-purpose

Naming a Branch: - Start branch name with the Issue Number: #1 Initial Issue > 1-initial-branch-name - Use lowercase only - Use dashes to separate words

Make awesome commits

Commits are the smallest portion of code that can be reviewed and has a purpose in the codebase. Each commit counts in a branch, not only the full set of changes.

Please follow this guideline: https://udacity.github.io/git-styleguide/

To use cool github linking to the issue please add #taskNumber in the end. E.g.:

docs: add changes to the Readme #123

Documentation

Please make sure that each public class, method and function has meaningful documentation which describes the purpose of the code. To make things easier to follow we use Python annotations to the public functions and method. Cheat sheet: https://mypy.readthedocs.io/en/latest/cheat_sheet_py3.html
