If you don't like the inefficiency of generic foreign keys, and you
know in advance which models in your project will be tagged,
django-taggit also supports tagging with direct foreign keys. You must
create your own intermediary model, a subclass of
``taggit.models.TaggedItemBase`` with a foreign key to your content
model named ``content_object``, and then pass this intermediary model
as the ``through`` argument of ``TaggableManager``::
from django.db import models
from taggit.managers import TaggableManager
from taggit.models import TaggedItemBase
class TaggedFood(TaggedItemBase):
content_object = models.ForeignKey('Food')
class Food(models.Model):
# ... fields here
tags = TaggableManager(through=TaggedFood)
Once this is done, the API works identically with direct-tagged or
GFK-tagged models.
``django-taggit`` requires Django 1.1 or greater. ``django-taggit`` requires Django 1.1 or greater.

The API
=======
After you've got your ``TaggableManager`` added to your model you can start
playing around with the API.
add(*tags)
~~~~~~~~~~
This adds tags to an object, the tags can be either ``Tag`` instances, or
strings::
>>> apple.tags.all()
[]
>>> apple.tags.add("red", "green", "fruit")
remove(*tags)
~~~~~~~~~~~~~
Removes a tag from an object, no exception is raised if the object doesn't have
that tag.
clear()
~~~~~~~
Removes all tags from an object.
set(*tags)
~~~~~~~~~~
Removes all the current tags and then adds the specified tags to the object.
most_common()
~~~~~~~~~~~~~
Returns a ``QuerySet`` of all tags, annotated with the number of times they
appear, available as the ``num_times`` attribute on each tag. The ``QuerySet``
is ordered by ``num_times``, descending. The ``QuerySet`` is lazily evaluated,
and can be sliced efficiently.

Using a Custom Through Model
============================
By default ``django-taggit`` uses a "through model" with a ``GenericForeignKey``
on it. However, there are some cases where this isn't desirable, for example
if you want the speed and referential guarntees of a real ``ForeignKey``, or if
you have a model with a non-integer primary key. In these cases ``django-taggit``
makes it easy to subsistute your own through model.
You must create your own intermediary model, a subclass of
``taggit.models.TaggedItemBase`` with a foreign key to your content model named
``content_object``, and then pass this intermediary model as the ``through``
argument of ``TaggableManager``::
from django.db import models
from taggit.managers import TaggableManager
from taggit.models import TaggedItemBase
class TaggedFood(TaggedItemBase):
content_object = models.ForeignKey('Food')
class Food(models.Model):
# ... fields here
tags = TaggableManager(through=TaggedFood)
Once this is done, the API works identically with direct-tagged or
GFK-tagged models.
Getting Started
===============
To get started using ``django-taggit`` simply install it ``pip``::
$ pip install django-taggit
Add it to your project's ``INSTALLED_APPS`` setting.
And then to any model you want tagging on do the following::
from django.db import models
from taggit.managers import TaggableManager
class Food(models.Model):
# ... fields here
tags = TaggableManager()
Welcome to django-taggit's documentation!
=========================================
``django-taggit`` is a reusable Django application designed to making adding
tagging to your project easy and fun.
