django-taggit a simpler approach to tagging with Django. Add "taggit" to your
INSTALLED_APPS then just add a TaggableManager to your model and go:
from django.db import models
from taggit.managers import TaggableManager
class Food(models.Model):
# ... fields here
tags = TaggableManager()
Then you can use the API like so:
>>> apple = Food.objects.create(name="apple")
>>> apple.tags.add("red", "green", "delicious")
>>> apple.tags.all()
[<Tag: red>, <Tag: green>, <Tag: delicious>]
>>> apple.tags.remove("green")
>>> apple.tags.all()
[<Tag: red>, <Tag: delicious>]
>>> Food.objects.filter(tags__name__in=["red"])
[<Food: apple>, <Food: cherry>]
Tags will show up for you automatically in forms and the admin.
django-taggit requires Django 1.4.5 or greater.
If you want to enforce lowercase tags everywhere (recommended, to avoid ending up with tags 'Music' and 'music' which are functionally identical but show up in different taxonomies), add to settings.py:
TAGGIT_FORCE_LOWERCASE = True
If you want to prevent certain words from being added as tags (such as English articles to, from, the, of, etc.) add to settings.py:
TAGGIT_STOPWORDS = [u'a', u'an', u'and', u'be', u'from', u'of']
