Django Tagging Changelog
SVN Trunk Changes:
* Added a ``tagging.generic`` module for working with list of objects
which have generic relations, containing a ``fetch_content_objects``
function for retrieving content objects for a list of ``TaggedItem``s
using ``number_of_content_types + 1`` queries rather than the
``number_of_tagged_items * 2`` queries you'd get by iterating over the
list and accessing each item's ``object`` attribute.
* Added a ``usage`` method to ``ModelTagManager``.
* ``TaggedItemManager``'s methods now accept a ``QuerySet`` or a
``Model`` class. If a ``QuerySet`` is given, it will be used as the
basis for the ``QuerySet``s the methods return, so can be used to
restrict results to a subset of a model's instances. The
`tagged_object_list`` generic view and ModelTaggedItemManager``
manager have been updated accordingly.
* Removed ``tagging\tests\``, as tests can be run with
`` test --settings=tagging.tests.settings``.
* A ``tagging.TagDescriptor`` is now added to models when registered.
This returns a ``tagging.managers.ModelTagManager`` when accessed on a
model class, and provide access to and control over tags when used on
an instance.
* Added ``tagging.register`` to register models with the tagging app.
Initially, a ``tagging.managers.ModelTaggedItemManager`` is added for
convenient access to tagged items.
* Moved ``TagManager`` and ``TaggedItemManager`` to ```` - gets
rid of some import related silliness, as ``TagManager`` needs access
to ``TaggedItem``.
Version 0.2.1, 16th Jan 2008:
* Fixed a bug with space-delimited tag input handling - duplicates
weren't being removed and the list of tag names wasn't sorted.
Version 0.2, 12th Jan 2008:
Packaged from revision 122 in Subversion; download at
* Added a ``tag_cloud_for_model`` template tag.
* Added a ``MAX_TAG_LENGTH`` setting.
* Multi-word tags are here - simple space-delimited input still works.
Double quotes and/or commas are used to delineate multi- word tags.
As far as valid tag contents - anything goes, at least initially.
* BACKWARDS-INCOMPATIBLE CHANGE - ``django.utils.get_tag_name_list`` and
related regular expressions have been removed in favour of a new tag
input parsing function, ``django.utils.parse_tag_input``.
* BACKWARDS-INCOMPATIBLE CHANGE - ``Tag`` and ``TaggedItem`` no longer
declare an explicit ``db_table``. If you can't rename your tables,
you'll have to put these back in manually.
* Fixed a bug in calculation of logarithmic tag clouds - ``font_size``
attributes were not being set in some cases when the least used tag in
the cloud had been used more than once.
* For consistency of return type, ``TaggedItemManager.get_by_model`` now
returns an empty ``QuerySet`` instead of an empty ``list`` if
non-existent tags were given.
* Fixed a bug caused by ``cloud_for_model`` not passing its
``distribution`` argument to ``calculate_cloud``.
* Added ``TaggedItemManager.get_union_by_model`` for looking up items
tagged with any one of a list of tags.
* Added ``TagManager.add_tag`` for adding a single extra tag to an
* Tag names can now be forced to lowercase before they are saved to the
database by adding the appropriate ``FORCE_LOWERCASE_TAGS`` setting to
your project's settings module. This feature defaults to being off.
* Fixed a bug where passing non-existent tag names to
``TaggedItemManager.get_by_model`` caused database errors with some
* Added ``tagged_object_list`` generic view for displaying paginated
lists of objects for a given model which have a given tag, and
optionally related tags for that model.
Version 0.1, 30th May 2007:
