Django-tree-queries

~~~~~~~~~~~~~~~~~~~

.. _0.7: https://github.com/matthiask/django-tree-queries/compare/0.6...0.7

- Added a test with a tree node having a UUID as its primary key.

~~~~~~~~~~~~~~~~~~~

- Fixed ``TreeQuerySet.ancestors`` to support primary keys not named ``id``.
- Changed the tree compiler to only post-process its own database results.
- Added ``**kwargs``-passing to ``TreeQuery.get_compiler`` for compatibility
with Django 4.0.

~~~~~~~~~~~~~~~~~~~

- Added support for adding tree fields to queries by default. Create a
manager using ``TreeQuerySet.as_manager(with_tree_fields=True)``.
- Ensured the availability of the ``with_tree_fields`` configuration
also on subclassed managers, e.g. those used for traversing reverse
relations.
- Dropped compatibility with Django 1.8 to avoid adding workarounds to
the testsuite.
- Made it possible to use django-tree-queries in more situations involving
JOINs. Thanks Safa Alfulaij for the contribution!

~~~~~~~~~~~~~~~~~~~

- Fixed a grave bug where a position of ``110`` would be sorted before
``20`` for obvious reasons.
- Added a custom ``TreeNodeForeignKey.deconstruct`` method to avoid
migrations because of changing field types.
- Removed one case of unnecessary fumbling in ``Query``'s internals
making things needlessly harder than they need to be. Made
django-tree-queries compatible with Django's master branch.
- Removed Python 3.4 from the Travis CI job list.
- Dropped the conversion of primary keys to text on PostgreSQL. It's a
documented constraint that django-tree-queries only supports integer
primary keys, therefore the conversion wasn't necessary at all.
- Reverted to using integer arrays on PostgreSQL for ordering if
possible instead of always converting everything to padded strings.

~~~~~~~~~~~~~~~~~~~

- Added a ``label_from_instance`` override to the form fields.
- Removed the limitation that nodes can only be ordered using an integer
field within their siblings.
- Changed the representation of ``tree_path`` and ``tree_ordering`` used
on MySQL/MariaDB and sqlite3. Also made it clear that the
representation isn't part of the public interface of this package.

~~~~~~~~~~~~~~~~~~~

- Added an optional argument to ``TreeQuerySet.with_tree_fields()`` to
allow reverting to a standard queryset (without tree fields).
- Added ``tree_queries.fields.TreeNodeForeignKey``,
``tree_queries.forms.TreeNodeChoiceField`` and
``tree_queries.forms.TreeNodeMultipleChoiceField`` with node depth
visualization.
- Dropped Python 3.4 from the CI.
