"basic relationship" examples, cleaned up the examples and added some more explicitness. Also renamed "treenodes" to "nodes" and added self-referential declarative example. - Added info/examples on how to join tables directly when querying with joined table inheritance. - Starting to talk about hybrids in the main mapper docs some more. introducoed the idea that synonyms are on their way out. - SQL expressions as mapped attributes also gets better verbiage, alternative approaches to them, including hybrids. - modernized the hybrid example. - object_session() as a standalone function wasn't documented ?!
SQLAlchemy
++++++++++
The Python SQL Toolkit and Object Relational Mapper
Requirements
------------
SQLAlchemy requires Python 2.4 or higher. One or more DB-API implementations
are also required for database access. See docs/intro.html for more
information on supported DB-API implementations.
Python 3 Compatibility
----------------------
Please see README.py3k for Python 3 installation and testing instructions.
Installation Tools
------------------
Installation is supported with standard Python distutils, as well
as with setuptools or Distribute. Distribute is recommended.
Distribute can be installed using the provided "distribute_setup.py"
script. The original setuptools may be installed using the
"ez_setup.py" script if preferred, or simply do nothing and distutils
will be used.
Installing
----------
To install::
python setup.py install
To use without installation, include the ``lib`` directory in your Python
path.
Installing the C extension
--------------------------
If installing with Setuptools or Distribute, the C extensions are built
and installed using the --with-cextensions flag:
python setup.py --with-cextensions install
If using plain Distutils, change the BUILD_CEXTENSIONS flag in setup.py
to "True".
Running Tests
-------------
Please see README.unittests for full instructions on running unit tests.
