django-leaderboard-template

A Django leaderboard app template, using redis as its backend. This app is a wrapper for the python-leaderboard api https://github.com/agoragames/leaderboard-python

The app uses Redis key-value pairs for its back-end and stores the scores on its 'sorted set' data structure, which keeps the data ordered and allows us to retrieve, update and delete scores efficiently.

With this app, you can get the leaderboard with pagination, create scores, update or delete them. Even get rankings around the given score.

Features

• RESTful api for creating, updating, deleting and retrieving high scores or scores around the user
• Standard view for displaying high scores with pagination

Not implemented features

• delete method for the api

Requirements

Python leaderboards module pip install leaderboard, note that this module will install redis and hiredis modules as its dependancy djangorestframework pip install djangorestframework for providing the rest behavior. pip freeze > requirements.txt to save all dependency requirements into a text file.

Usage

Thanks to djangorestframework, you can just visit http://localhost:8000/leaderboard/api/<game-identifier>/ to create, update or get the leaderboard.

Other urls are http://localhost:8000/leaderboard/api/<game-identifier>/user/<user-id>/ for scores around the user, and http://localhost:8000/leaderboard/api/<game-identifier>/<page-id>/ for pagination. Please see urls.py to see the full list or urls.

To create new ranking using the api, send a POST request to http://localhost:8000/leaderboard/api/<game-identifier>/. Game identifier is the key to determine your game to the system. it can be anything. Parameters are user_idand score.

To see the html table of leaderboard, go to http://localhost:8000/leaderboard/highscores/<game-identifier>/ page.
