Parking Permits API

Backend repository for parking permits service developed by City of Helsinki.

Instructions in this README.md are written with an experienced Python developer in mind. For example, "docker-compose up" means you already know what docker and docker-compose are and you already have both installed locally. This helps to keep the README.md concise.

Setting up local development environment with Docker

In order to create placeholder for your own environment variables file, copy and rename .env.example to .env.

You'll need a redhat developer account to gain access to RedHat subscriptions needed to run the docker image.

Register at https://developers.redhat.com/register and confirm your email address.

Set following environment variables in .env file:

  • BUILD_MODE=local
  • REDHAT_USERNAME=your redhat account username
  • REDHAT_PASSWORD=your redhat account password

Then you can run docker image with:

docker-compose up

  • Access development server on localhost:8000

  • Login to admin interface with admin and 🥥

  • Done!

Setting up local development environment with PyEnv and VirtualEnvWrapper

pyenv install -v 3.9.0
pyenv virtualenv 3.9.0 parking_permits
pyenv local parking_permits
pyenv virtualenvwrapper

Install packages

pip install -U pip pip-tools
pip-compile -U requirements.in
pip-compile -U requirements-dev.in
pip-sync requirements.txt requirements-dev.txt

Managing project packages

  • We use pip-tools to manage python packages we need

  • After adding a new package to requirements(-dev).in file, compile it and re-build the Docker image so that the container would have access to the new package

    docker-compose up --build

Running tests

  • You can run all the tests with:

    docker-compose exec graphql-api pytest

  • If you want to run the tests continously while developing:

    • Install fd using brew or equivalent

    • Install entr using brew or equivalent

    • Run pytest whenever a Python file changes with:

      fd --extension py | entr -c docker-compose exec graphql-api pytest
