Fix typo: replace "can can" to "can"
2012-11-02Deprecated depth kwarg on select_related.Preston Holmes
This is the start of a deprecation path for the depth kwarg on select_related. Removing this will allow us to update select_related so it chains properly and have an API similar to prefetch_related. Thanks to Marc Tamlyn for spearheading and initial patch. refs #16855

2012-09-28Fixed #18676 -- Allow fast-path deletion of objectsAnssi Kääriäinen
Objects can be fast-path deleted if there are no signals, and there are no further cascades. If fast-path is taken, the objects do not need to be loaded into memory before deletion. Thanks to Jeremy Dunck, Simon Charette and Alex Gaynor for reviewing the patch.

2012-09-05Fixed #18904 - Typo in MySQL link; thanks Johie Anderson for the report.Tim Graham
2012-08-12Fixed #18306 -- Made deferred models issue update_fields on saveAndrei Antoukh
Deferred models now automatically update only the fields which are loaded from the db (with .only() or .defer()). In addition, any field set manually after the load is updated on save.
2012-07-17Fixed #17788 -- Added batch_size argument to qs.bulk_create()Anssi Kääriäinen
The qs.bulk_create() method did not work with large batches together with SQLite3. This commit adds a way to split the bulk into smaller batches. The default batch size is unlimited except for SQLite3 where the batch size is limited to 999 SQL parameters per batch. Thanks to everybody who participated in the discussions at Trac.
2012-07-07Removed Django 1.0-specific sections.Aymeric Augustin
2012-06-26Fixed #17485 -- Made defer work with select_relatedAnssi Kääriäinen
This commit tackles a couple of issues. First, in certain cases there were some mixups if field.attname or field.name should be deferred. Field.attname is now always used. Another issue tackled is a case where field is both deferred by .only(), and selected by select_related. This case is now an error. A lot of thanks to koniiiik (Michal Petrucha) for the patch, and to Andrei Antoukh for review.

2011-12-22Added support for modifying the effect of ``DISTINCT`` clauses so theyRamiro Morales
only consider some fields (PostgreSQL only). For this, the ``distinct()`` QuerySet method now accepts an optional list of model fields names and generates ``DISTINCT ON`` clauses on these cases. Thanks Jeffrey Gelens and Anssi Kääriäinen for their work. Fixes #6422. git-svn-id: http://code.djangoproject.com/svn/django/trunk@17244 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2011-10-10Removed use of non-standard indentation rules in docs, and the custom ↵Luke Plant
transform that supported them. Doc writers should be aware that we are now back to normal ReST rules regarding blockquotes. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16955 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2011-08-27Extensive copy-editing and cross-referencing in the queryset API docs.Malcolm Tredinnick
Been meaning to do this for a long time. Mostly, this is a lot of additions of cross references. Within a particular section about foo() I didn't cross-link foo() calls to itself, but everything else was cross-linked to its main documentation. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16699 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2011-08-26Corrected explanation of values() and extra() interaction in querysets.Malcolm Tredinnick
Fixes #15546, refs #13455. The original documentation patch inadvertently muddied the waters in one aspect and this commit tidies that up. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16697 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2011-08-26Clarify the documentation around SQLite and case-sensitive string matching.Malcolm Tredinnick
This was still causing some confusion, so I rewrote the section in the database notes to encompass both substring matching and non-ASCII case-insensitive equality checks, as well as putting in a stronger callout on the "contains" filter. Refs #16569. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16694 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2011-08-26Be very clear about when it's appropriate to use defer() and only().Malcolm Tredinnick
I've been seeing a bit of over-reliance on defer() and only() in code around the place and it's generally better modelled with normalised data or shadow (unmanaged) models. This commit makes this position clearer. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16692 bcc190cf-cafb-0310-a4f2-bffc1f526a37
