Tracking Trunk (1:08)

• QuerySet Refactor Cleanup – Several tickets related to QuerySet Refactor merge and unrelated but just database stuff in general:
  • Corrected DateQuerySet to handle nullable fields (7739) – Previously if the date field was nullable no results were returned.
  • Corrected values and values_list across nullable joins (7740) – Previously, if we were querying across a nullable join and then a non-nullable one, the second join would not be a LEFT OUTER join, which would exclude certain valid results from the result set.
  • (7741), (7773), and (7760) through (7766) – Lots of miscellaneous QuerySet changes
  • Delete multi-table objects correctly. (7784) – When model inheritance is used, the parent objects should be deleted as part of the delete() call on the child.
