Fixed bug in “evaluate” strategy of Query.update() and Query.delete() which would fail to accommodate a bound parameter with a “callable” value, as which occurs when filtering by a many-to-one equality expression along a relationship. Fixed bug whereby the event listeners used for backrefs could be inadvertently applied multiple times, when using a deep class inheritance hierarchy in conjunction with mutiple mapper configuration steps. Fixed bug whereby passing a text() construct to the Query.group_by() method would raise an error, instead of intepreting the object as a SQL fragment. Anonymous labeling is applied to a func construct that is passed to column_property(), so that if the same attribute is referred to as a column expression twice the names are de-duped, thus avoiding “ambiguous column” errors. Previously, the .label(None) would need to be applied in order for the name to be de-anonymized. Fixed regression appearing in the 1.0 series in ORM loading where the exception raised for an expected column missing would incorrectly be a NoneType error, rather than the expected NoSuchColumnError. |
