nearing the end of the 0.1 series, as some major reorganization is going on for the 0.2 series. 0.2 will be mostly backwards compatible, but some code might need some name changes so the 0.1 series will still be available.
changes for 0.1.6: 0.1.6 - support for MS-SQL added courtesy Rick Morrison, Runar Petursson - the latest SQLSoup from J. Ellis - ActiveMapper has preliminary support for inheritance (Jeff Watkins) - added a "mods" system which allows pluggable modules that modify/augment core functionality, using the function "install_mods(*modnames)". - added the first "mod", SelectResults, which modifies mapper selects to return generators that turn ranges into LIMIT/OFFSET queries (Jonas Borgström) - factored out querying capabilities of Mapper into a separate Query object which is Session-centric. this improves the performance of mapper.using(session) and makes other things possible. - objectstore/Session refactored, the official way to save objects is now via the flush() method. The begin/commit functionality of Session is factored into LegacySession which is still established as the default behavior, until the 0.2 series. - types system is bound to an engine at query compile time, not schema construction time. this simplifies the types system as well as the ProxyEngine. - added 'version_id' keyword argument to mapper. this keyword should reference a Column object with type Integer, preferably non-nullable, which will be used on the mapped table to track version numbers. this number is incremented on each save operation and is specifed in the UPDATE/DELETE conditions so that it factors into the returned row count, which results in a ConcurrencyError if the value received is not the expected count. - added 'entity_name' keyword argument to mapper. a mapper is now associated with a class via the class object as well as an optional entity_name parameter, which is a string defaulting to None. any number of primary mappers can be created for a class, qualified by the entity name. instances of those classes will issue all of their load and save operations through their entity_name-qualified mapper, and maintain separate a identity in the identity map for an otherwise equilvalent object. - overhaul to the attributes system. code has been clarified, and also fixed to support proper polymorphic behavior on object attributes. - added "for_update" flag to Select objects - some fixes for backrefs - fix for postgres1 DateTime type - documentation pages mostly switched over to Markdown syntax ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
