Mostly just formatting and rewording, but also replaced the example using ``YearExtract`` to use an example which is unlikely to ever be possible directly in the ORM. commit 250900650628d1f11beadb22814abd666029fb81 Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Sun Jan 12 13:19:13 2014 +0200 Removed unused import commit 4fba5dfaa022653ffa72497258ffd8f8b7476f92 Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Sat Jan 11 22:34:41 2014 +0200 Added docs to index commit 6d53963f375c77a1f287833b19b976d23f36c30b Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Sat Jan 11 22:10:24 2014 +0200 Dead code removal commit f9cc0390078e21f1ea5a7bc1f15b09f8f6b0904d Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Sat Jan 11 19:00:43 2014 +0200 A new try for docs commit 33aa18a6e3c831930bda0028222a26f9c1d96e66 Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Sat Jan 11 14:57:12 2014 +0200 Renamed get_cols to get_group_by_cols commit c7d5f8661b7d364962bed2e6f81161c1b4f1bcc3 Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Sat Jan 11 14:45:53 2014 +0200 Altered query string customization for backends vendors The new way is trying to call first method 'as_' + connection.vendor. If that doesn't exist, then call as_sql(). Also altered how lookup registration is done. There is now RegisterLookupMixin class that is used by Field, Extract and sql.Aggregate. This allows one to register lookups for extracts and aggregates in the same way lookup registration is done for fields. commit 90e7004ec14e15503f828cc9bde2a7dab593814d Merge: 66649ff f7c2c0a Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Sat Jan 11 13:21:01 2014 +0200 Merge branch 'master' into lookups_3 commit 66649ff891c7c73c7eecf6038c9a6802611b5d8a Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Sat Jan 11 13:16:01 2014 +0200 Some rewording in docs commit 31b8faa62714b4b6b6057a9f5cc106c4dd73caab Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Sun Dec 29 15:52:29 2013 +0200 Cleanup based on review comments commit 1016159f34674c0df871ed891cde72be8340bb5d Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Sat Dec 28 18:37:04 2013 +0200 Proof-of-concept fix for #16731 Implemented only for SQLite and PostgreSQL, and only for startswith and istartswith lookups. commit 193cd097ca8f2cc6a911e57b8e3fb726f96ee6a6 Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Sat Dec 28 17:57:58 2013 +0200 Fixed #11722 -- iexact=F() produced invalid SQL commit 08ed3c3b49e100ed9019831e770c25c8f61b70f9 Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Sat Dec 21 23:59:52 2013 +0200 Made Lookup and Extract available from django.db.models commit b99c8d83c972786c6fcd0e84c9e5cb08c1368300 Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Sat Dec 21 23:06:29 2013 +0200 Fixed review notes by Loic commit 049eebc0703c151127f4f0265beceea7b8b39e72 Merge: ed8fab7 b80a835 Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Sat Dec 21 22:53:10 2013 +0200 Merge branch 'master' into lookups_3 Conflicts: django/db/models/fields/__init__.py django/db/models/sql/compiler.py django/db/models/sql/query.py tests/null_queries/tests.py commit ed8fab7fe8867ff3eb801c3697a426478387bb2f Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Sat Dec 21 22:47:23 2013 +0200 Made Extracts aware of full lookup path commit 27a57b7aed91b2f346abc4a77da838bffa17c727 Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Sun Dec 1 21:10:11 2013 +0200 Removed debugger import commit 074e0f5aca0572e368c11e6d2c73c9026e7d63d7 Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Sun Dec 1 21:02:16 2013 +0200 GIS lookup support added commit 760e28e72bae475b442b026650969b0d182dbe53 Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Sun Dec 1 20:04:31 2013 +0200 Removed usage of Constraint, used Lookup instead commit eac47766844b90e7d3269e7a8c012eee34ec0093 Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Sun Dec 1 02:22:30 2013 +0200 Minor cleanup of Lookup API commit 2adf50428d59a783078b0da3d5d035106640c899 Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Sun Dec 1 02:14:19 2013 +0200 Added documentation, polished implementation commit 32c04357a87e3727a34f8c5e6ec0114d1fbbb303 Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Sat Nov 30 23:10:15 2013 +0200 Avoid OrderedDict creation on lookup aggregate check commit 7c8b3a32cc17b4dbca160921d48125f1631e0df4 Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Sat Nov 30 23:04:34 2013 +0200 Implemented nested lookups But there is no support of using lookups outside filtering yet. commit 4d219d4cdef21d9c14e5d6b9299d583d1975fcba Author: Anssi Kääriäinen <akaariai@gmail.com> Date: Wed Nov 27 22:07:30 2013 +0200 Initial implementation of custom lookups

2013-09-30Fixed #21134 -- Prevented queries in broken transactions.Aymeric Augustin
Squashed commit of the following: commit 63ddb271a44df389b2c302e421fc17b7f0529755 Author: Aymeric Augustin <aymeric.augustin@m4x.org> Date: Sun Sep 29 22:51:00 2013 +0200 Clarified interactions between atomic and exceptions. commit 2899ec299228217c876ba3aa4024e523a41c8504 Author: Aymeric Augustin <aymeric.augustin@m4x.org> Date: Sun Sep 22 22:45:32 2013 +0200 Fixed TransactionManagementError in tests. Previous commit introduced an additional check to prevent running queries in transactions that will be rolled back, which triggered a few failures in the tests. In practice using transaction.atomic instead of the low-level savepoint APIs was enough to fix the problems. commit 4a639b059ea80aeb78f7f160a7d4b9f609b9c238 Author: Aymeric Augustin <aymeric.augustin@m4x.org> Date: Tue Sep 24 22:24:17 2013 +0200 Allowed nesting constraint_checks_disabled inside atomic. Since MySQL handles transactions loosely, this isn't a problem. commit 2a4ab1cb6e83391ff7e25d08479e230ca564bfef Author: Aymeric Augustin <aymeric.augustin@m4x.org> Date: Sat Sep 21 18:43:12 2013 +0200 Prevented running queries in transactions that will be rolled back. This avoids a counter-intuitive behavior in an edge case on databases with non-atomic transaction semantics. It prevents using savepoint_rollback() inside an atomic block without calling set_rollback(False) first, which is backwards-incompatible in tests. Refs #21134. commit 8e3db393853c7ac64a445b66e57f3620a3fde7b0 Author: Aymeric Augustin <aymeric.augustin@m4x.org> Date: Sun Sep 22 22:14:17 2013 +0200 Replaced manual savepoints by atomic blocks. This ensures the rollback flag is handled consistently in internal APIs.

2013-06-10Added a stealth option to flush to allow cascades.Aymeric Augustin
This allows using flush on a subset of the tables without having to manually cascade to all tables with foreign keys to the tables being truncated, when they're known to be empty. On databases where truncate is implemented with DELETE FROM, this doesn't make a difference. The cascade is allowed, not mandatory.

2013-03-23Fixed #9055 -- Standardized behaviour of parameter escaping in db cursorsClaude Paroz
Previously, depending on the database backend or the cursor type, you'd need to double the percent signs in the query before passing it to cursor.execute. Now cursor.execute consistently need percent doubling whenever params argument is not None (placeholder substitution will happen). Thanks Thomas Güttler for the report and Walter Doekes for his work on the patch.

2012-11-27Fixed #19274 -- Made db connection creation overridable in subclassesAnssi Kääriäinen
Connection creation was done in db backend ._cursor() call. This included taking a new connection if needed, initializing the session state for the new connection and finally creating the connection. To allow easier modifying of these steps in subclasses (for example to support connection pools) the _cursor() now calls get_new_connection() and init_connection_state() if there isn't an existing connection. This was done for all non-gis core backends. In addition the parameters used for taking a connection are now created by get_connection_params(). We should also do the same for gis backends and encourage 3rd party backends to use the same pattern. The pattern is not enforced in code, and as the backends are private API this will not be required by documentation either.
