0.9 (2018-09-20)

Bugfixes

  • Stop using the internals of QuerySet for better forward compatibility. This change means that QuerySetSequence is no longer a sub-class of QuerySet and should improve interactions with other packages which modify QuerySet. (#38)

  • Support Django REST Framework 3.7 and 3.8. (#33, #39)

Maintenance

  • Support Django 1.11. Contributed by @michael-k. (#26, #32)

Maintenance

  • Support Django REST Framework 3.5. (#20)

0.7 (2016-10-20)

  • 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)

Bugfixes

  • PartialInheritanceMeta must be provided INHERITED_ATTRS and NOT_IMPLEMENTED_ATTRS. (#12)

Maintenance

  • Move queryset_sequence to an actual module in order to hide some implementation details. (#11)

Maintenance

  • Support Django 1.10. (#9)

0.6 (2016-06-07)

  • Support exists() to check if a QuerySetSequence has any results. (1aa705b)

  • Support select_related to follow foreign-key relationships when generating results. (ad54d5e)

Bugfixes

  • Do not cache the results when calling iterator(). (6566a91)
