Anssi Kääriäinen e74787391e Fixed a regression introduced in where.as_sql() refactor
At least Oracle needs parentheses in negated where conditions, even if
there is only single condition negated. Fixed this by reverting to old
logic in that part of as_sql() and adding a comment about this.

I did not investigate why the parentheses are needed. The original
offending commit was bd283aa844.

Anssi Kääriäinen bd283aa844 Refactored the empty/full result logic in WhereNode.as_sql()
Made sure the WhereNode.as_sql() handles various EmptyResultSet and
FullResultSet conditions correctly. Also, got rid of the FullResultSet
exception class. It is now represented by '', [] return value in the
as_sql() methods.

Anssi Kääriäinen b6c356b7bb Fixed #17485 -- Made defer work with select_related
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.

Anssi Kääriäinen 8c72aa2379 Fixed qs.order_by() join promotion for already existing joins
When order_by causes new joins to be added to the query, the joins must
be LEFT OUTER joins for nullable relations, otherwise the order_by
could cause the results to be altered. This commit fixes the logic to
only promote new joins, previously all joins in the order_by lookup
path were promoted.

Thanks to Bruno Desthuilliers for spotting this corner case.

Claude Paroz df7a65ac4b Replaced 'next' testing by collections.Iterator testing.
The new construct is also Python 3 compatible (where 'next' has
been renamed to '__next__').

Anssi Kääriäinen d5c7f9efc3 Fixed #18304 -- Optimized save() when update_can_self_select=False
Databases with update_can_self_select = False (MySQL for example)
generated non-necessary queries when saving a multitable inherited
model, and when the save resulted in update.
2012-05-22 20:59:33 +03:00
Claude Paroz 169b1a404c Replaced foo.next() by next(foo).
This new syntax for next() has been introduced in Python 2.6 and is
compatible with Python 3.

Anssi Kääriäinen c2e1ecb4b1 Fix proxy model Query.remove_inherited_models()
Fixed #18248 -- proxy models were added to included_inherited_models
in sql.query.Query. The variable is meant to be used for multitable
inheritance only. This mistake caused problems in situations where
proxy model's query was reused.

Anssi Kääriäinen 584e2c0337 Prevent Oracle from changing field.null to True
Fixed #17957 -- when using Oracle and character fields, the fields
were set null = True to ease the handling of empty strings. This
caused problems when using multiple databases from different vendors,
or when the character field happened to be also a primary key.

The handling was changed so that NOT NULL is not emitted on Oracle
even if field.null = False, and field.null is not touched otherwise.

Thanks to bhuztez for the report, ramiro for triaging & comments,
ikelly for the patch and alex for reviewing.

Anssi Kääriäinen 5aa51fa999 Simplified QuerySet field.null handling
QuerySet had previously some complex logic for dealing with nullable
fields in negated add_filter() calls. It seems the logic is leftover
from a time where the WhereNode wasn't as intelligent in handling
field__in=[] conditions.

Thanks to aaugustin for comments on the patch.

Ramiro Morales 287565779d Added support for modifying the effect of ``DISTINCT`` clauses so they
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.

Malcolm Tredinnick c3a0dcf6e9 Added convenience method for viewing Query SQL without params.
This is the old Query.as_sql() method revived: it's like Query.__str__,
but the parameters aren't substituted into the placeholders. Thus, it's
a more accurate representation of the SQL the (default) backend will
see. Entirely internal.

Jacob Kaplan-Moss fd2f18008c Fixed #14733: no longer "validate" .raw() queries.
Turns out that a lot more than just SELECT can return data, and this list is
very hard to define up front in a cross-database manner. So let's just assume
that anyone using raw() is at least halfway competant and can deal with
the error messages if they don't use a data-returning query.

Thanks to Christophe Pettus for the patch.

This removes a long-standing FIXME in the update() handling and allows for
greater flexibility in the values passed in. In particular, it brings updates
into line with saves for django.contrib.gis fields, so fixed #10411.

This fixes a broad class of bugs involving filters that look for missing

also fixed #9868.

Malcolm Tredinnick 0e93f60c7f Fixed #10362 -- An update() that only affects a parent model no longer crashes.
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.

Malcolm Tredinnick 14c8e5227a Changed the row count value returned from update queries in some cases.
If an update only affected an ancestor model (not the child), we were
returning 0 for the number of rows updated. This could have been
misleading if the value is used to detect an update occuring. So we now
return the rowcount from the first non-trivial query that is executed
(if any). Still a slight compromise, but better than what we had.

Malcolm Tredinnick 062a94ef45 Reconciling where- and having-clause behaviour.
Extricated the code that works directly with SQL columns (standard
"where" stuff) from the the code that takes SQL fragments and combines
it with lookup types and values. The latter portion is now more
generally reusable. Any existing code that was poking at Query.having
will now break in very visible ways (no subtle miscalculations, which is
a good thing).

This patch, en passant, removes the existing "having" test, since the
new implementation requires more setting up than previously. The
aggregates support (currently in a separate codebase) has tests for this
functionality that work as a replacement for the removed test.

Malcolm Tredinnick a1cbeb9afb If an SQL query doesn't specify any ordering, avoid the implicit sort
that happens with MySQL when a "GROUP BY" clause is included. This is a
backend-specific operation, so any other databases requiring similar
encouragement can have a function added to their own backend code.

Also comes with approximately 67% less stupidity in the table joins for
filtering on generic relations.

Fixed #5937, hopefully for good, this time.

Malcolm Tredinnick d70c8907cd Fixed #5937 -- When filtering on generic relations, restrict the target objects to those with the right content type.
This isn't a complete solution to this class of problem, but it will do for
1.0, which only has generic relations as a multicolumn type. A more general
multicolumn solution will be available after that release.

and models that have multiple paths to them from other models.

Malcolm Tredinnick d4d7bc175d Fixed #8046 -- The first filter() call on a related manager for many-to-many
fields no longer creates duplicate copies of the join table(s). Basically, this
means filters on the join table (for ManyToManyField(through=...)) and complex
filters in the normal (non-through) case don't produce incorrect or duplicate
results.

Malcolm Tredinnick 2c4b13cbe7 Changed the (internal) way extra(select=.., select_params=...) handling is done
so that parameters stay with their select items. This means that merging and
trimming of those items is handled correctly.

Refs #7957, #7961. Fixed #8191.

Jacob Kaplan-Moss 34a3bd5225 Major refactoring of django.dispatch with an eye towards speed. The net result is that signals are up to 90% faster.
Though some attempts and backwards-compatibility were made, speed trumped compatibility. Thus, as usual, check BackwardsIncompatibleChanges for the complete list of backwards-incompatible changes.

Thanks to Jeremy Dunck and Keith Busell for the bulk of the work; some ideas from Brian Herring's previous work (refs #4561) were incorporated.

Documentation is, sigh, still forthcoming.

Fixes #6814 and #3951 (with the new dispatch_uid argument to connect).

Malcolm Tredinnick a7b556ca04 Allow for matches against unsaved objects in querysets (which will therefore
match nothing). This allows for some more straightforward code in the admin
interface.

down to the item in this patch).

Malcolm Tredinnick 6dd2b5468f Redo the changes in [7773] in a better way.
This removes some of the leaky abstraction problems (lifting WhereNode
internals into the Query class) from that commit and makes it possible for
extensions to WhereNode to have access to the field instances. It's also
backwards-compatible with pre-[7773] code, which is also better.

This avoids any use of "pk is not NULL" fragment, which behave inconsistently

suggesting the easy fix.

Also added a section to the documentation to indicate why it's probably not a

applies even to Django code.
