François Freitag 6b6be692fc Refs #16614 -- Prevented database errors from being masked by cursor close.
When an error occurred during the cursor.execute statement, the cursor
is closed. This operation did not fail with client-side cursors. Now,
with server-side cursors, the close operation might fail (example
below). The original error should be raised, not the one raised by
cursor.close(), this is only clean-up code.

For example, one can attempt to create a named cursor for an invalid
query. psycopg will raise an error about the invalid query and the
server-side cursor will not be created on PostgreSQL. When the code
attempts to cursor.close(), it asks psycopg to close a cursor that was
not created. pyscopg raises a new error: psycopg2.OperationalError:
cursor "_django_curs_140365867840512_20" does not exist.

Thanks to Josh Smeaton for the idea of implementing server-side cursors
in PostgreSQL from the iterator method, and Anssi Kääriäinen and Kevin
Turner for their previous work. Also Simon Charette and Tim Graham for
review.

Anssi Kääriäinen adc57632bc Fixed #24748 -- Fixed incorrect GROUP BY on MySQL in some queries
When the query's model had a self-referential foreign key, the
compiler.get_group_by() code incorrectly used the self-referential
foreign key's column (for example parent_id) as GROUP BY clause
when it should have used the model's primary key column (id).

Field.rel is now deprecated. Rel objects have now also remote_field
attribute. This means that self == self.remote_field.remote_field.

In addition, made the Rel objects a bit more like Field objects. Still,
marked ManyToManyFields as null=True.

Anssi Kääriäinen b68212f539 Refs #24267 -- Implemented lookups for related fields
Previously related fields didn't implement get_lookup, instead

instances now, too.

Other notable changes in this commit is removal of support for
annotations in names_to_path().
2015-03-25 08:05:22 -04:00
Anssi Kääriäinen fb146193c4 Fixed #24171 -- Fixed failure with complex aggregate query and expressions
The query used a construct of qs.annotate().values().aggregate() where
the first annotate used an F-object reference and the values() and
aggregate() calls referenced that F-object.

Also made sure the inner query's select clause is as simple as possible,
and made sure .values().distinct().aggreate() works correctly.
2015-03-09 07:49:23 -04:00
Marc Tamlyn 32d4db66b9 Update converters to take a consistent set of parameters.
As suggested by Anssi. This has the slightly strange side effect of
