When I look at: row.keys() ['id', 'name', 'name'] This is with SA 0.8.1. Anyone has some tips on how I could make Dabo ReportWriter happy.

[sqlalchemy] Dabo ReportDesigner/Writer
Hi, I am looking at Dabo's ReportDesigner/Writer to do reporting (looked at others like PythonReports and Geraldo) but both have problems with large text blobs. It wants the data as: Dabo's reportwriter wants dataset-like structures, which is a sequence (list, tuple) of mappings (dict), where each key in the mapping is a field name, and each item in the outer sequence is a record. I managed to figure this out: result = session.query(db.Cellarbook.avgpurchaseprice, db.Drinkinfo.name) result = result.join(db.Drinkinfo) print result for row in result.all(): print row.__dict__['name'] Is using row.__dict__ the correct way or are there other ways?
