[sqlalchemy] Re: @comparable_using
I got around this by switching to declarative and declaring my property like this: _id = column_property(Column(id,Integer,primary_key=True), comparator_factory=some_comparator_factory()) And then used @synonym_for for the getter: @synonym_for(_id) @property def id(self): return some_function(self._id) I'm still not sure what was wrong with my original code, so would be interested in any comments, for academic reasons.

If you were using mapper(), you'd take the output from comparable_using and pass it to the properties dictionary of mapper() - but more likely you'd use comparable_property() directly pass your comparator straight in to column_property(), as introduced in http://www.sqlalchemy.org/docs/mappers.html#custom-comparators and linking to an example at http://www.sqlalchemy.org/docs/reference/orm/mapping.html#sqlalchemy.orm.comparable_property .

Re: [sqlalchemy] Re: @comparable_using
After fixing my cutpaste problem I just get DB2 sql errors from the sample code. I'm going to turn on some more logging in db2 and see what is actually reaching it.
