Development with Docker

Prerequisites:

• Docker
• Docker Compose

1. Create a docker-compose.env.yaml file in the project folder:

   • Use docker-compose.env.yaml.example as a base, it does not need any changes for getting the project running.
   • Set entrypoint/startup variables according to taste.
     • DEBUG, controls debug mode on/off
     • APPLY_MIGRATIONS, applies migrations on startup
     • CREATE_ADMIN_USER, creates an admin user with credentials admin:(password, see below) (admin@hel.ninja)
     • ADMIN_USER_PASSWORD, the admin user's password. If this is not given, a random password is generated and written into stdout when an admin user is created automatically.

2. Run docker-compose up

   • The project is now running at localhost:8081

Optional steps

1. Run migrations:

   • Taken care by the example env
   • docker exec atv-backend python manage.py migrate

2. Create superuser:

   • Taken care by the example env
   • docker exec -it atv-backend python manage.py add_admin_user

Development without Docker

Prerequisites:

• PostgreSQL 14
• Python 3.11

Installing Python requirements

• Run pip install -r requirements.txt
• Run pip install -r requirements-dev.txt (development requirements)

Database

To setup a database compatible with default database settings:

Create user and database

sudo -u postgres createuser -P -R -S atv  # use password `atv`
sudo -u postgres createdb -O atv atv

Allow user to create test database

sudo -u postgres psql -c "ALTER USER atv CREATEDB;"

Daily running

• Create .env file: touch .env

DEBUG=1
DATABASE_URL=postgres://atv:atv@localhost:5437/atv

# Optionals (with a default value on settings.py)
FIELD_ENCRYPTION_KEYS=

• Set the DEBUG environment variable to 1.
• Run python manage.py migrate
• Run python manage.py add_admin_user
• Run python manage.py runserver 0:8000

The project is now running at localhost:8000

Keeping Python requirements up to date

1. Install pip-tools:

   • pip install pip-tools

2. Add new packages to requirements.in or requirements-dev.in

3. Update .txt file for the changed requirements file:

   • pip-compile requirements.in
   • pip-compile requirements-dev.in

4. If you want to update dependencies to their newest versions, run:

   • pip-compile --upgrade requirements.in

5. To install Python requirements run:

   • pip-sync requirements.txt

Code format

This project uses black, flake8 and isort for code formatting and quality checking. Project follows the basic black config, without any modifications.

Basic black commands:

• To let black do its magic: black .
• To see which files black would change: black --check .

pre-commit can be used to install and run all the formatting tools as git hooks automatically before a commit.

Running tests

• Set the DEBUG environment variable to 1.
• Run pytest.
