2008-06-26Fixed #7105 -- Fixed dates() queries in light of model inheritance.Malcolm Tredinnick
git-svn-id: http://code.djangoproject.com/svn/django/trunk@7763 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2008-06-26Removed the bulk of the sanity checking when merging QuerySets.Malcolm Tredinnick
It was causing too many inconvenient and unintended problems when merging legitimate subclasses (e.g. with geo-django classes). There's still a hook there that we use when merging ValueQuerySets, but if you try to merge two disparate QuerySets and it breaks all that happens is you get to keep both pieces. We're no longer penalising the useful usages just for the people who aren't concentrating. Fixed #7113. git-svn-id: http://code.djangoproject.com/svn/django/trunk@7742 bcc190cf-cafb-0310-a4f2-bffc1f526a37

select dictionary containing more than a few elements. This bug was identified in unit test from [5767].
