====== Models ====== Tagulous provides two new :doc:`model fields ` - :ref:`model_tagfield` and :ref:`model_singletagfield`, which you use to add tags to your existing models to make them :doc:`tagged models `. They provide extra tag-related functionality. They can also be queried like a normal Django ``ForeignKey`` or ``ManyToManyField``, but with extra :ref:`query enhancements ` to make working with tags easier. Tags are stored in :doc:`tag model ` subclasses, which can either be unique to each different tag field, or can be shared between them. If you don't specify a tag model on your field definition, one will be created for you automatically. Tags can be nested using :doc:`tag trees `. There is also support for :doc:`database migrations `. .. toctree:: :maxdepth: 2 fields tag_models tag_trees tagged_models migrations
