I want to make a custom type and I'm not sure whether to use UserDefinedType or TypeDecorator.
for a UserDefinedType it seems I must write "bind_processor" and " result_processor" or for TypeDecorator it seems I must write "process_bind_param" and "process_result_value" I think I need a UserDefinedType as I'm combining two primitive types rather than specialising one. I want Vector2D(float, float) and an ordered list of such vectors and to pass these into the DB using something as close as possible to Python such as [(ax, ay), (bx, by), (cx, cy)] After reading some doco and posts I'm still unclear exactly what the functions I have to write should do as they often seem to do very little. Really, I just want to insert tuples into columns. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
