Django APIs for physics conversion and calculations

Geocurrency

API service that provides

• List of countries according to ISO-3166
• List of currencies according to ISO-4217
• List of conversion rates fetched from BCE APIs
• Custom conversion rates support by key
• List of units and Unit Systems
• Conversions from from and to currencies
• Conversion from and to units

Install

Preparation

set the following environment variables

• VENV_DIR: virtualenv directory
• GEOCURRENCY_SRC: Source directory for geocurrency
• GEOCURRENCY_DB_NAME: database name
• GEOCURRENCY_DB_USERNAME: database username
• GEOCURRENCY_DB_PASSWORD: database password

Docker

Create a "packages" directory at the root of the project Generate packages from "build.sh"

Folder "deployment/docker" provides an easy to setup docker environment running

• Django app
• Redis cache
• Postgres backend
• nginx load balancer

just run "docker-compose up"

Using packages

ENV_NAME=<env_name> PROJECT_NAME=<project_name> PYTHON_VERSION=/usr/bin/python3 # use pypy :) virtualenv -p $PYTHON_VERSION $ENV_NAME cd $ENV_NAME source bin/activate pip install geocurrency django-admin startproject $PROJECT_NAME cp site_packages/geocurrency/core/settings.example.py $PROJECT_NAME/$PROJECT_NAME/settings.py cp site_packages/geocurrency/core/urls.example.py $PROJECT_NAME/$PROJECT_NAME/urls.py cd $PROJECT_NAME

Adapt settings and urls for your environment.

Usage

Routes

This package provides a OpenAPI documentation. See urls.example.py for a setup example.

Authentication

The app provides most services without authentication. Authentication is required to store custom conversion rates and custom conversion units. By default, the app is configured to allow authentication through an API token that can be generated for a user on the Django admin site.

API authentication can be achieved with an Authorization header header with value Token curl -H "Authorization: Token ".

Language support

The app supports translations for countries and units in 15 languages. More languages should be available soon.

Fetch rates

The app uses python-forex as a mecanism to fetch currency rates. A django command is available to fetch rates from command line : $ ./manage.py fetch_rates

About

Project goals

Web based services to convert units and currencies. GeoCurrency is a portmanteau of the words "Geocoding" and "Currency" which where the main goals of the initial project
