Set up

cp .envrc.example .envrc

# add SMPT credentials (optional) in .envrc
vim .envrc

python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

Database

This project uses SQLite. To create the database and schema and apply migrations, run:

python manage.py migrate

Data

Production vaccine and disease data are serialised and committed to the repository, file name is vaccine-disease-data.json.

To load all vaccine and disease data, run:

python manage.py loaddata --app main vaccine-disease-data.json

Note: The above command needs to run after the migration command.

To dump/serialise all vaccine and disease data, run:

python manage.py dumpdata main.Vaccine main.Disease > vaccine-disease-data.json

Serve

To run the Django development server:

python manage.py runserver

Testing

Using the Django test runner:

python manage.py test

For coverage, run:

make cov

Code linting & formatting

The following tools are used for code linting and formatting:

• black for code formatting.
• isort for imports order consistency.
• flake8 for code linting.

To use:

make format
make lint

Deployment

Deployment is configured with nginx as a reverse proxy and uWSGI in Emperor mode. Configuration files:

• allthevaccines.org.conf: nginx reverse proxy configuration
• emperor.ini: uWSGI main configuration, enables emperor mode
• uwsgi.ini: uWSGI vassal configuration
