working correctly with single table inheritance
for a relationship from a subclass - the "where
type in (x, y, z)" only gets placed on the inside,
instead of repeatedly.
- When using from_self() with single table inheritance,
the "where type in (x, y, z)" is placed on the outside
of the query only, instead of repeatedly. May make
some more adjustments to this.
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.
