Hello again ! This is a bugfix release and is recommended for all users who are currently on 0.4.2 or 0.4.2a. There is one critical bugfix which involves history calculation on collection-based attributes. Other significant bugfixes include a potential error that can arise with "delete-orphan" cascade, a fix to synonym() regarding backrefs, some more advanced collections behavior fixes, a datetime-related fix to the MSSQL dialects, and a fix for the the "order_by(None)" call which can be used on a select() object in order to clear the criterion.
Also, we just released two days ago and the changelog already has 11 new items. Geez ! download the latest and greatest at: http://www.sqlalchemy.org/download.html 0.4.2b ------ - sql - changed name of TEXT to Text since its a "generic" type; TEXT name is deprecated until 0.5. The "upgrading" behavior of String to Text when no length is present is also deprecated until 0.5; will issue a warning when used for CREATE TABLE statements (String with no length for SQL expression purposes is still fine) [ticket:912] - generative select.order_by(None) / group_by(None) was not managing to reset order by/group by criterion, fixed [ticket:924] - orm - suppressing *all* errors in InstanceState.__cleanup() now. - fixed an attribute history bug whereby assigning a new collection to a collection-based attribute which already had pending changes would generate incorrect history [ticket:922] - fixed delete-orphan cascade bug whereby setting the same object twice to a scalar attribute could log it as an orphan [ticket:925] - Fixed cascades on a += assignment to a list-based relation. - synonyms can now be created against props that don't exist yet, which are later added via add_property(). This commonly includes backrefs. (i.e. you can make synonyms for backrefs without worrying about the order of operations) [ticket:919] - fixed bug which could occur with polymorphic "union" mapper which falls back to "deferred" loading of inheriting tables - the "columns" collection on a mapper/mapped class (i.e. 'c') is against the mapped table, not the select_table in the case of polymorphic "union" loading (this shouldn't be noticeable). - ext - '+', '*', '+=' and '*=' support for association proxied lists. - dialects - mssql - narrowed down the test for "date"/"datetime" in MSDate/ MSDateTime subclasses so that incoming "datetime" objects don't get mis-interpreted as "date" objects and vice versa, [ticket: 923] --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
