[soc2009/multidb] Renaming of database attributes - you now use NAME, ENGINE, etc rather than DATABASE_NAME, DATABASE_ENGINE inside DATABASES. Also deprecates the use of short names (.e.g., `sqlite3` for backends in ENGINE). Patch from Russell Keith-Magee.

@ -7,9 +7,6 @@ Required for v1.2
* Finalize the sql.Query internals
* Clean up the use of db.backend.query_class()
* Verify it still works with GeoDjango
* Resolve the public facing UI issues around using multi-db
* Should we take the opportunity to modify DB backends to use fully qualified paths?
* Should we clean up DATABASES['DATABASE_NAME'] to DATABASES['NAME'] etc?
* Cleanup of new API entry points
* validate() on a field
* name/purpose clash with Honza?

Database-backend-specific SQL data
----------------------------------
There's also a hook for backend-specific SQL data. For example, you can have
separate initial-data files for PostgreSQL and MySQL. For each app, Django
looks for a file called ``<appname>/sql/<modelname>.<backend>.sql``, where
``<appname>`` is your app directory, ``<modelname>`` is the model's name in
lowercase and ``<backend>`` is the value of ``DATABASE_ENGINE`` for the given
database being set up in your settings file (e.g., ``postgresql``, ``mysql``).

database with an :setting:`ENGINE` value of
``django.db.backends.postgresql``, Django will look for
``<appname>/sql/<modelname>.postgresql.sql``).
Backend-specific SQL data is executed before non-backend-specific SQL data. For
example, if your app contains the files ``sql/person.sql`` and
``sql/person.postgresql.sql`` and you're installing the app on PostgreSQL,
Django will execute the contents of ``sql/person.postgresql.sql`` first, then

Specifying databases
--------------------
Prior to Django 1.1, Django used a number of settings to control access to a
single database. Django 1.2 introduces support for multiple databases, and as
a result, the way you define database settings has changed.
Previously, there were a number of ``DATABASE_`` settings at the top level of
your settings file. For example::
DATABASE_NAME = 'test_db'
DATABASE_BACKEND = 'postgresl_psycopg2'
DATABASE_USER = 'myusername'
DATABASE_PASSWORD = 's3krit'
These settings are now contained inside a dictionary named
``DATABASES``. Each item in the dictionary corresponds to a single
database connection, with the name ``default`` describing the default
database connection. The setting names have also been shortened to
reflect the fact that they are stored in a dictionary. The sample
settings given previously would now be stored using::
DATABASES = {
'default': {
'NAME': 'test_db',
'BACKEND': 'django.db.backends.postgresl_psycopg2',
'USER': 'myusername',
'PASSWORD': 's3krit',
}
This affects the following settings:
Old setting New Setting
========================================= ===========
:setting:`DATABASE_ENGINE` ENGINE
:setting:`DATABASE_HOST` HOST
:setting:`DATABASE_NAME` NAME
:setting:`DATABASE_OPTIONS` OPTIONS
:setting:`DATABASE_PASSWORD` PASSWORD
:setting:`DATABASE_PORT` PORT
:setting:`DATABASE_USER` USER
:setting:`TEST_DATABASE_CHARSET` TEST_CHARSET
:setting:`TEST_DATABASE_COLLATION` TEST_COLLATION
:setting:`TEST_DATABASE_NAME` TEST_NAME
These changes are also required if you have manually created a database
connection using
In addition to the change in structure, Django 1.2 removes the special
handling for the built-in database backends. All database backends
must now be specified by a fully qualified class name (i.e.,
``django.db.backends.postgresl_psycopg2``, rather than just
``postgresql_psycopg2``)
``__dict__`` on Model instances
-------------------------------
Historically, the ``__dict__`` attribute of a model instance has only contained
attributes corresponding to the fields on a model.
In order to support multiple database configurations, Django 1.2 has
added a ``_state`` attribute to object instances. This attribute will
appear in ``__dict__`` for a model instance. If your code relies on
iterating over __dict__ to obtain a list of fields, you must now
filter out ``_state`` attribute of out ``__dict__``.

Django 1.2 adds the ability to use :ref:`more than one database

issued at a specific database with the `using()` method on
querysets; individual objects can be saved to a specific database
