I'm pleased to announce the release of PyDO-2.0b2.
* the project() method now takes the keyword argument "mutable", which
overrides the mutability of the base class.
* new, more declarativeshortcuts for defining associations between
tables: ForeignKey, OneToMany, and ManyToMany.
* several bugfixes, with corresponding tests.
What it is
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
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
* 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.
* PyDO2 supports runtime table introspection.
* Overall, the API has been tightened and the code restructured.
PyDO 2 requires Python 2.4 or later. It currently supports
PostgreSQL, MySQL, Sqlite, MSSQL, and Oracle, and support for other
databases is planned.
PyDO is dual GPL/BSD licensed.
