django-compressedlistfield

django-compressedlistfield provides a Django model field which stores a compressed, auto growing, list of integers.

It uses bz2 for compresing the list, but you don't have to worry about it as it transparently takes care of serialization. To use, simply add the field to one of your models.

Python 3 & Django 1.8 through 1.11 supported!

Installation

pip install django-compressedlistfield

Usage

from django.db import models
from compressedlistfield import CompressedListField

class Achievement(models.Model):
  scores = CompressedListField()

scores is of type AutoGrowingList whose base is list and where empty entries are represented by the lists empty property.

Other Classes

compressedlistfield.AutoGrowingList

An extension of the builtin list that supports auto expansion and one based indexing. Uses the EMPTY constant to mark empty cells and used by CompressedListField for the datastore.

Testing django-compressedlist Locally

To test against all supported versions of Django:

$ docker-compose build && docker-compose up

Or just one version (for example Django 1.11 on Python 3.5):

$ docker-compose build && docker-compose run tox tox -e py35-1.11

Or, you can create a virtualenv, install the django you want to test and run:

$ python setup.py test
