2009-12-21[soc2009/multidb] A couple of cleanups of multi-db support for raw queries, ↵Alex Gaynor
including a using() call on raw query sets. Patch from Russell Keith-Magee. git-svn-id: http://code.djangoproject.com/svn/django/branches/soc2009/multidb@11930 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2009-12-12[soc2009/multidb] Merged in all of Justin Bronn's GIS work. Multidb should ↵Alex Gaynor
now work fully with GIS. This is backwards incompatible, if you are using GIS, your ENGINE setting should now be django.contrib.gis.db.backends.XXX where XXX is the name of your DB backend. Thanks to Justin for all his work.

2009-05-11Fixed #10953, #10955: proxies of proxies now work correctly, though I still ↵Jacob Kaplan-Moss
don't quite understand why you'd want to do such a thing. Thanks, Armin Ronacher. git-svn-id: http://code.djangoproject.com/svn/django/trunk@10738 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-04-30Fixed #10847 -- Modified handling of extra() to use a masking strategy, ↵Russell Keith-Magee
rather than last-minute trimming. Thanks to Tai Lee for the report, and Alex Gaynor for his work on the patch. This enables querysets with an extra clause to be used in an __in filter; as a side effect, it also means that as_sql() now returns the correct result for any query with an extra clause. git-svn-id: http://code.djangoproject.com/svn/django/trunk@10648 bcc190cf-cafb-0310-a4f2-bffc1f526a37

expression. Thanks, Alex Gaynor. git-svn-id: http://code.djangoproject.com/svn/django/trunk@10357 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-04-01Fixed #9871 -- Geometry objects are now returned in dictionaries and tuples ↵Justin Bronn
returned by `values()` and `values_list()`, respectively; updated `GeoQuery` methods to be compatible with `defer()` and `only`; removed defunct `GeomSQL` class; and removed redundant logic from `Query.get_default_columns`. git-svn-id: http://code.djangoproject.com/svn/django/trunk@10326 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-03-24Fixed #9926 -- Fixes for some select_related() situations.Malcolm Tredinnick
Using select_related(...) across a nullable relation to a multi-table model inheritance situation no longer excludes results. Thanks to AdamG for a test demonstrating part of the problem. git-svn-id: http://code.djangoproject.com/svn/django/trunk@10136 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-03-19Fixed #5420 -- Added support for delayed loading of model fields.Malcolm Tredinnick
In extreme cases, some fields are expensive to load from the database (e.g. GIS fields requiring conversion, or large text fields). This commit adds defer() and only() methods to querysets that allow the caller to specify which fields should not be loaded unless they are accessed. git-svn-id: http://code.djangoproject.com/svn/django/trunk@10090 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-03-18Fixed #10356 -- Added pure-Python inheritance for models (a.k.a proxy models).Malcolm Tredinnick
Large portions of this are needed for #5420, so I implemented it fully. Thanks to Ryan Kelly for an initial patch to get this started. Refs #5420. git-svn-id: http://code.djangoproject.com/svn/django/trunk@10083 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-03-14Fixed #10425 -- Corrected the interaction of .count() with .annotate() when ↵Russell Keith-Magee
.values() is also involved. Thanks to kmassey for the report. git-svn-id: http://code.djangoproject.com/svn/django/trunk@10053 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2009-03-06Improved table join handling for comparisons against NULL.Malcolm Tredinnick
This fixes a broad class of bugs involving filters that look for missing related models and fields. Most of them don't seem to have been reported (the added tests cover the root cause). The exception is that this has also fixed #9868. git-svn-id: http://code.djangoproject.com/svn/django/trunk@9979 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2009-03-04Fixed #10362 -- An update() that only affects a parent model no longer crashes.Malcolm Tredinnick
This includes a fairly large refactor of the update() query path (and the initial portions of constructing the SQL for any query). The previous code appears to have been only working more or less by accident and was very fragile. git-svn-id: http://code.djangoproject.com/svn/django/trunk@9967 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-03-01Fixed insert/update handling when no database interaction is required.Malcolm Tredinnick
Fixed #10205 as part of this. git-svn-id: http://code.djangoproject.com/svn/django/trunk@9926 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-03-01Fixed #10202 -- Fixed another couple of slicing edge-cases with querysets.Malcolm Tredinnick
Patch from Alex Gaynor and Ramiro Morales. git-svn-id: http://code.djangoproject.com/svn/django/trunk@9924 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-02-28Fixed #10028 -- Fixed a problem when ordering by related models.Malcolm Tredinnick
Some results were inadvertently being excluded if we were ordering across a nullable relation which itself ordering by a non-nullable relation. git-svn-id: http://code.djangoproject.com/svn/django/trunk@9916 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-02-25Fixed #10290: do not use aliases when adding extra_selects to the GROUP BY ↵Ian Kelly
clause, to generate compliant sql that will be accepted by Oracle. git-svn-id: http://code.djangoproject.com/svn/django/trunk@9905 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-02-23Fixed #10182 -- Corrected realiasing and the process of evaluating values() ↵Russell Keith-Magee
for queries with aggregate clauses. This means that aggregate queries can now be used as subqueries (such as in an __in clause). Thanks to omat for the report. This involves a slight change to the interaction of annotate() and values() clauses that specify a list of columns. See the docs for details. git-svn-id: http://code.djangoproject.com/svn/django/trunk@9888 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-02-16Fixed #10248 -- Corrected handling of the GROUP BY clause when using a ↵Russell Keith-Magee
DateQuerySet. Thanks to Alex Gaynor for the report and patch. git-svn-id: http://code.djangoproject.com/svn/django/trunk@9839 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-02-16Fixed #10132 -- Corrected the interaction of extra() queries with the ↵Russell Keith-Magee
values() clause. Thanks to Glen Maynard for the report. git-svn-id: http://code.djangoproject.com/svn/django/trunk@9838 bcc190cf-cafb-0310-a4f2-bffc1f526a37

Thanks to Sylvain Pasche <sylvain.pasche@gmail.com> for the report and test case. git-svn-id: http://code.djangoproject.com/svn/django/trunk@9805 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-01-29Fixed #7210 -- Added F() expressions to query language. See the ↵Russell Keith-Magee
documentation for details on usage. Many thanks to: * Nicolas Lara, who worked on this feature during the 2008 Google Summer of Code. * Alex Gaynor for his help debugging and fixing a number of issues. * Malcolm Tredinnick for his invaluable review notes. git-svn-id: http://code.djangoproject.com/svn/django/trunk@9792 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-01-24Refs #10113 -- Modified the generated SQL to remove redundant GROUP BY ↵Russell Keith-Magee
elements, and modified the test added in [9788] to remove a test result that depended on a potentially ambiguous database ordering. git-svn-id: http://code.djangoproject.com/svn/django/trunk@9791 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-01-24Fixed #10113 -- Ensured that joined fields mentioned in order_by() are ↵Russell Keith-Magee
