I need to implement an indexu-style category tree of arbitrary depth: News & Media (64) Arts and Humanities, Automotive, Business....
Recreation & Sports (234) Amusement and Theme Parks, Automotive, Aviation.... Reference (32) Acronyms and Abbreviations, Almanacs, Arts and Humanities.... Product items with arbitrary properties will be associated with multiple product categories. The eventual rendering will be in TurboGears or Django, the database postgresql. Being new to both sqlalchemy and SQL tree models, I'd like to start by learning the proper nomenclature: What is this data structure called, particularly in sqlalchemy parlance? I'd imagine this is a fairly common pattern in applications built on top of sqlalchemy. Can anyone direct me to a python/sqlalchemy open-source project using this kind of category directory, so that I can study their implementation? I'm hoping to properly utilize sqlalchemy to manage parent-child relationships (especially for moving nodes), so that I don't end up parsing a stored string path field or anything naive. Thanks for any suggestions. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
