Django-querysetsequence

================

Improvements
------------

* Allow filtering / querying / ordering by the order of the ``QuerySets`` in the
``QuerySetSequence`` by using ``''``. This allows for additional optimizations
when using third-party applications, e.g. Django REST Framework.

`16 <https://github.com/clokep/django-querysetsequence/pull/16>`_)
* `Django REST Framework`_ integration: includes a subclass of the
``CursorPagination`` from Django REST Framework under
``queryset_sequence.pagination.SequenceCursorPagination`` which is designed to
work efficiently with a ``QuerySetSequence`` by first ordering by internal
``QuerySet``, then by the ``ordering`` attribute. (`17 <https://github.com/clokep/django-querysetsequence/pull/17>`_)

Bugfixes
--------

* ``PartialInheritanceMeta`` must be provided ``INHERITED_ATTRS`` and
``NOT_IMPLEMENTED_ATTRS``. (`12 <https://github.com/clokep/django-querysetsequence/pull/12>`_)

Maintenance
-----------

* Move ``queryset_sequence`` to an actual module in order to hide some
implementation details. (`11 <https://github.com/clokep/django-querysetsequence/pull/11>`_)

==================

Maintenance
-----------

* Support Django 1.10. (`9 <https://github.com/clokep/django-querysetsequence/pull/9>`_)

================

Improvements
------------

* Allow specifying the ``Model`` to use when instantiating a ``QuerySetSequence``.
This is required for compatibility with some third-party applications that check
the ``model`` field for equality, e.g. when using the ``DjangoFilterBackend``
with Django REST Framework. Contributed by `CountZachula <https://github.com/CountZachula>`_.
(`6 <https://github.com/clokep/django-querysetsequence/pull/6>`_)
* Support ``prefetch_related``. (`7 <https://github.com/clokep/django-querysetsequence/pull/7>`_)

Bugfixes
--------

* Fixes an issue when using Django Debug Toolbar. (`8 <https://github.com/clokep/django-querysetsequence/pull/8>`_)

================

Improvements
------------

* Significant performance improvements when ordering the
``QuerySetSequence``. (`5 <https://github.com/clokep/django-querysetsequence/pull/5>`_)
* Support ``delete()`` to remove items. (`1bb1716 <https://github.com/clokep/django-querysetsequence/commit/1bb1716eeedb37d6323f5578de565eaf09cc94b3>`_)

Maintenance
-----------

* Support Python 3.4 and 3.5. Contributed by `jpic <https://github.com/jpic>`_.
(`3 <https://github.com/clokep/django-querysetsequence/pull/3>`_)

================

Improvements
------------

* Raises ``NotImplementedError`` for ``QuerySet`` methods that ``QuerySetSequence``
does not implement. (`e2c67c5 <https://github.com/clokep/django-querysetsequence/commit/e2c67c5070cbd7a88249b3537c14b9536d4eaee4>`_,

* Support ``reverse()`` to reverse the item ordering. (`f27b2c7 <https://github.com/clokep/django-querysetsequence/commit/f27b2c76432e1e7ed7092056671cd5e9f6ed4b59>`_)
* Support ``none()`` to return an ``EmptyQuerySet``. (`6171c11 <https://github.com/clokep/django-querysetsequence/commit/6171c1113adc55d4fd16fea762233580ff992112>`_)
* Support ``exists()`` to check if a ``QuerySetSequence`` has any results. (`1aa705b <1aa705b53cebd8dde028d2bd1e2380db8b301049>`_)
* Support ``select_related`` to follow foreign-key relationships when generating results.

Bugfixes
--------

* Do not evaluate any ``QuerySets`` when calling ``filter()`` or ``exclude()``
like a Django ``QuerySet``. Contributed by
