COVID-19 Tracker

A map that allows people with COVID-19 to mark their past locations to warn others that might have come into contact with them.

Demo / staging

Embeding the map

Seting up local environment

The app is written in Python, using Pyramid framework.

We use virtualenvs and docker-compose to simplify development.

First, create a virtual environment.

python3 -m venv venv

Install the Python dependencies.

venv/bin/pip install -e ".[testing]"

If psycopg2 install fails, you might have some build dependencies missing. A possible workaround is to replace psycopg2 with psycopg2-binary.

Run

docker-compose up -d

to setup a PostgreSQL database.

Then you must migrate the DB using

venv/bin/alembic -c development.ini upgrade head

(The -x argument is a hack, the connection string should ideally be taken from development.ini. See #58.)

To load some sample data, run the following:

venv/bin/initialize_back_db development.ini

Run the development server with

venv/bin/pserve development.ini

DB migrations

venv/bin/alembic -c development.ini revision --autogenerate -m "init"

Translations

After modifyning translation files, they need to be compiled from .mo to .po.

msgfmt -o back/locale/en/LC_MESSAGES/messages.mo back/locale/en/LC_MESSAGES/messages.po

Adding translatable strings

cd back/locale
vim messages.pot # add new entry
vim back/locale/en/LC_MESSAGES/messages.mo

Adding new translations

Change XX into the desired locale name.

cp back/locale/messages.pot back/locale/XX/LC_MESSAGES/messages.po
