2008-04-24queryset-refactor: Changed the way order_by() and distinct() interact.Malcolm Tredinnick
When using "select distinct" all ordering columns must be part of the output (select) columns. We were previously just throwing away ordering columns that weren't included, but there are some cases where they are needed and it's difficult to add them in manually. So now the default behaviour is to append any missing columns. This can affect the output of distinct() if complicated order_by() constructs are used, so the documentation has been updated with an explanation of what's going on there. Fixed #7070. git-svn-id: http://code.djangoproject.com/svn/django/branches/queryset-refactor@7455 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2008-04-24queryset-refactor: Added a note about using already present tables inMalcolm Tredinnick
extra(tables=...). This is already a problem in trunk and it's pretty much impossible to work around in a non-complex way, so it's user beware (it's usually easy enough to avoid the problems). git-svn-id: http://code.djangoproject.com/svn/django/branches/queryset-refactor@7453 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2008-04-24queryset-refactor: Renamed the Queryset method valueslist() to values_list.Malcolm Tredinnick
Suggested by Michael Trier. It's more consistent with order_by, select_related, etc. This is backwards incompatible for people previously using this method on the branch (the method doesn't exist on trunk, so it's very minor). git-svn-id: http://code.djangoproject.com/svn/django/branches/queryset-refactor@7451 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2008-03-20queryset-refactor: Fixed up extra(select=...) calls with parameters so that theMalcolm Tredinnick
parameters are substituted in correctly in all cases. This introduces an extra argument to extra() for this purpose; no alternative there. Also fixed values() to work if you don't specify *all* the extra select aliases in the values() call. Refs #3141. git-svn-id: http://code.djangoproject.com/svn/django/branches/queryset-refactor@7340 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2008-03-18queryset-refactor: Undo [7220] and allow ordering on multi-valued field.Malcolm Tredinnick
Some people will shoot themselves in the foot with this. That's bad luck. The reason we need it is because some data semantics cannot be expressed in Django's ORM and that shouldn't prevent ordering on that data. For example, filtering suburbs by a geographic region and then ordering on the suburb names. The names might not be unique outside that region, but unique inside it. Django cannot know that (you can't tell the model about it), so we trust the caller. git-svn-id: http://code.djangoproject.com/svn/django/branches/queryset-refactor@7285 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2008-03-12queryset-refactor: Refactored the way values() works so that it works properlyMalcolm Tredinnick
across inherited models. Completely by accident, this also allows values() queries to include fields from related models, providing it is crossing a single-valued relation (one-to-one, many-to-one). Many-to-many values() fields still aren't supported, since that requires actual thinking. So this refs #5768. git-svn-id: http://code.djangoproject.com/svn/django/branches/queryset-refactor@7230 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2008-03-11queryset-refactor: Reorganised Model.save() to differentiate between public ↵Malcolm Tredinnick
and private parameters. Refs #6741. This means subclasses can override save() without needing to worry about passing around the internal parameters (an issue for subclassable models, which would have meant every model, since you don't know when somebody will subclass your model). Slightly backwards incompatible, since it moves "raw" back to being part of the internal API (it's only needed by the serializer and was intended to be internal use only). If external code really needs this, they can call Model.save_base() and pass in raw there. git-svn-id: http://code.djangoproject.com/svn/django/branches/queryset-refactor@7221 bcc190cf-cafb-0310-a4f2-bffc1f526a37

This adds both types of model inheritance: abstract base classes (ABCs) and multi-table inheritance. See the documentation and tests / examples for details.

Not quite ready for prime-time usage, but it mostly works as expected. git-svn-id: http://code.djangoproject.com/svn/django/branches/queryset-refactor@7126 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2008-02-08queryset-refactor: Fixed up OneToOneFields (mostly).Malcolm Tredinnick
They now share as much code as possible with ForeignKeys, but behave more or less as they did before (the backwards incompatible change is that they are no longer automatically primary keys -- so more than one per model is permitted). The documentation still uses an example that is better suited to model inheritance, but that will change in due course. Also, the admin interface still shows them as read-only fields, which is probably wrong now, but that can change on newforms-admin after this branch is merged into trunk. git-svn-id: http://code.djangoproject.com/svn/django/branches/queryset-refactor@7096 bcc190cf-cafb-0310-a4f2-bffc1f526a37

moving SQL out of the core code. Only direct fields and foreign keys can be updated in this fashion, since multi-table updates are very non-portable. This also cleans up the API for the UpdateQuery class a bit. Still need to change DeleteQuery to work similarly, I suspect.
