django-tags

django-tags a simpler approach to tagging with Django. Add "tags" to your INSTALLED_APPS then just add a TaggableManager to your model and go:

from django.db import models

from tags.fields import TagField

class Food(models.Model):
    # ... fields here

    tags = TagField('Tags')

Tags will show up for you automatically in forms and the admin.

django-tags requires Django 1.3 or greater.
