I'm pleased to announce the first alpha release of PyDO 2.
PyDO is Drew Csillag's ORM (Object-Relational Mapper) database access
library for Python that facilitates writing a Python database access
layer. PyDO attempts to be simple, flexible, extensible, and
unconstraining.
PyDO 2 is a rewrite of the 1.x series distributed with SkunkWeb.
It has several enhancements:
* PyDO can now be used in multi-threaded or twisted-style
asynchronous sitations, with or without a customizable connection
pool.
* PyDO objects are now dict subclasses, but also support attribute
access to fields.
* Projections -- subsets of the field list of a super-class -- are
now supported by the PyDO.project() method.
* Table attributes are now declared in a more concise way.
* Overall, the API has been tightened and the code restructured.
It also has several limitations:
* PyDO 2 is alpha code. Bugs should be expected, and the API is not
guaranteed to be stable.
* Currently, PyDO 2 supports fewer database systems than PyDO 1
(PostgreSQL, SQLite, and MySQL), although adding new drivers
should not be difficult.
* PyDO 2 requires Python 2.4 or later.
PyDO is dual GPL/BSD licensed.
The source tarball is available at SkunkWeb's berlios site:
