But how do I typecast a string to the type needed by a mapped class, which is identified at run time? I have a class, class Record(object): pass which I map to one of different tables identified at run time. I get strings like this col, val = raw_input(), raw_input() (my actual application uses HTML form, but this was for testing) which I try to use to insert a new record, like: rec = Record() setattr(rec, col, val) This works if col is a string (the column subclassing SQLAlchemy's String) but not otherwise. I can identify the type of the column as coltype = rec.c[col].type I probably can write a big if elif else to identify the type and do the typecasting. e.g.: if isinstance(coltype, Integer): val = int(val) but is there a canonical solution already there? for parsing HTML form data into Python objects most people use FormEncode: http://formencode.org/ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups sqlalchemy group.

FormEncode looks great and I will definitely be using it. Still, as I identify my object (column) classes at run-time, I need to find a mapping between sqlalchemy types and python types. I guess I will build a dictionary with the types I need. we do have a trac ticket for this idea, associating python types with SQL types, which we havent yet decided how we'd like to do. theres a bigger ticket for a rewrite of the types system which would probably address this issue. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups sqlalchemy group.
