Fabulous Tagging for Django

Django Tagulous - Fabulous Tags

A tagging library for Django. Built on ForeignKey and ManyToManyField to support tag strings as well as native ORM queries.

Use a SingleTagField as a CharField with dynamic choices, or a TagField for conventional tagging or nested categorisation.

Quickstart

Install with pip install django-tagulous, add tagulous to Django's INSTALLED_APPS and define the serializers, then start adding tag fields to your model:

from django.db import models
from tagulous.models import SingleTagField, TagField

class Person(models.Model):
    name = models.CharField(max_length=255)
    title = SingleTagField(initial="Mr, Mrs, Miss, Ms")
    skills = TagField()

You can now set and get them using strings, lists or querysets::

myperson = Person.objects.create(name='Bob', title='Mr', skills='run, hop')
# myperson.skills == 'run, hop'
myperson.skills = ['jump', 'kung fu']
myperson.save()
# myperson.skills == 'jump, "kung fu"'
runners = Person.objects.filter(skills='run')

Behind the scenes each tag field is a ForeignKey or ManyToManyField relationship to a separate model (by default), so more complex queries are simple::

qs = MyRelatedModel.objects.filter(
    person__skills__name__in=['run', 'jump'],
)

As well as this you also get autocompletion in public and admin forms, automatic slug generation, unicode support, you can build tag clouds easily, and can nest tags for more complex categorisation.
