Removed do_inline_sorting_url and get_object_or_404 check in admin. The model_type_id should *always* be passed in.
Removed test that asserted that Categories weren't sortable as part of the Project admin. Categories *should* be sortable as part of Project admin as they are a Sortable ForeignKey.
Fixed object_rep template to pass in model_type_id again.
Updated README.
Version bump to 2.0.21
Loading the test app '/admin/app/project/sort/' changelist failed with
the following error:
UnboundLocalError: local variable 'objects' referenced before assignment
(utils.py, check_model_is_sortable)
See test sample_app test_adminsortable_change_list_view_loads_with_sortable_fk
Removed utils file and moved map_path function to settings.py.
Refactored tests for Python 2 and 3 compatibility.
Added inheritance check to get proper determination if a SortableForeignKey field is defined but the specified model does not inherit from Sortable.
Added new get_permissions_codename check for permissions in upcoming Django 1.8.
Refactored all version checks. All checks are done in tuple format instead of checking for a django major and minor version number.
Removed unused RequestFactory in tests.
Fixed namespacing of so sorting urls.
Changed namespacing of sortable() calls.
Removed unit test to check for javascript include template, which has been eliminated.
Fixed a problem with the detection of sortability of inline models at the template level that was preventing the drag-and-drop messaging in the template to be displayed.
Updated unit tests.
Updated status to stable/production.
Added AttributeError exception handling for models that specify a SortableForeignKey that does not inherit from Sortable.
Added template support for nested objects that are sortable by a foreign key, where the foreign key is not sortable.
Refactored how the sortable_by properties get populated by looping over the model fields until we get to the SortableForeignKey, then grabbing properties from the field and its related data.
Refactored ORM calls to properly order objects by the sortable_by property to ensure objects are grouped correctly in the sortable change list template after being passed through dynamic_regroup.
Fixed missing import for jquery.effects.core, again.
Refactored sortable_by classmethod into a property.
Added backwards compatibility for pre 1.1.1 versions that still have sortable_by defined as a classmethod.
Need to address dynamic regroup template tag to see why categories are not being grouped properly in sample app.
