Model.save() will use UPDATE - if not updated - INSERT instead of
SELECT - if found UPDATE else INSERT. This should save a query when
updating, but will cost a little when inserting model with PK set.
Also fixed#17341 -- made sure .save() commits transactions only after
the whole model has been saved. This wasn't the case in model
inheritance situations.
The save_base implementation was refactored into multiple methods.
A typical chain for inherited save is:
save_base()
_save_parents(self)
for each parent:
_save_parents(parent)
_save_table(parent)
_save_table(self)
Replaced them with per-database options, for proper multi-db support.
Also toned down the recommendation to tie transactions to HTTP requests.
Thanks Jeremy for sharing his experience.

Removed redundant exception wrapping.
This is now taken care of by the cursor wrapper.
commit 524bc7345a724bf526bdd2dd1bcf5ede67d6bb5c
Author: Aymeric Augustin <aymeric.augustin@m4x.org>
Date: Tue Feb 26 14:55:10 2013 +0100
Wrapped database exceptions in the base backend.
This covers the most common PEP-249 APIs:
- Connection APIs: close(), commit(), rollback(), cursor()
- Cursor APIs: callproc(), close(), execute(), executemany(),
fetchone(), fetchmany(), fetchall(), nextset().
Fixed#19920.
commit a66746bb5f0839f35543222787fce3b6a0d0a3ea
Author: Aymeric Augustin <aymeric.augustin@m4x.org>
Date: Tue Feb 26 14:53:34 2013 +0100
Added a wrap_database_exception context manager and decorator.
It re-throws backend-specific exceptions using Django's common wrappers.
Changed the ip_address field for Comment to GenericIPAddressField. Added
instructions to the release notes on how to update the schema of existing
databases.
This controls whether or not a database level cosntraint is created. This is useful in a few specialized circumstances, but in general should not be used!
Thanks Carl Meyer for the review.

Used an absolute path for the SQLite database.
This ensures the settings file works regardless of which directory
django-admin.py / manage.py is invoked from.
BASE_DIR got a +1 from a BDFL and another core dev. It doesn't involve
the concept of a "Django project"; it's just a convenient way to express
relative paths within the source code repository for non-Python files.
Thanks Jacob Kaplan-Moss for the suggestion.

Author: Aymeric Augustin <aymeric.augustin@m4x.org>
Date: Mon Jan 28 15:51:50 2013 +0100
Normalized the default application template.
Removed the default test that 1 + 1 = 2, because it's been committed
way too many times, in too many projects.
Added an import of `render` for views, because the first view will
often be:
def home(request):
return render(request, "mysite/home.html")
They are handled independently now and the latter can be influenced by
the new BaseCommand.leave_locale_alone internal option.
Thanks chrischambers for the report, Claude, lpiatek, neaf and gabooo for
their work on a patch, originally on refs. #17379.
They are simply ignored now. This allows for a more correct behavior when
they are placed before translatable constructs on the same line.
Previously, the latter were wrongly ignored because the former were
preserved when converting template code to the internal Python-syntax
form later fed to xgettext but Python has no ``/* ... */``-style
comments.
Also, special comments directed to translators are now only taken in
account when they are located at the end of a line. e.g.::
{# Translators: ignored #}{% trans "Literal A" %}{# Translators: valid, associated with "Literal B" below #}
{% trans "Literal B" %}
Behavior of ``{% comment %}...{% endcomment %}``tags remains unchanged.
Thanks juneih at redpill-linpro dot com for the report and Claude for
his work on the issue.
Thanks a lot to everybody participating in developing this feature.
The patch was developed by multiple people, at least Trac aliases
tonnzor, jimmysong, Fandekasp and slurms.
Stylistic changes added by committer.
The guarantee that no queries will be made when accessing results is
done by new EmptyWhere class which is used for query.where and having.
Thanks to Simon Charette for reviewing and valuable suggestions.
