Hi, I'm trying to use non_primary arg of function 'mapper'.
Currently I have a GUI widget to browse/edit tables that is based on introspection of the mapper. My goal would be to reuse all the machinary of table browsing even when browsing tables tat where built w/o primary key. I'm ready to understand that I can't use persistence but I thought that flagging as a non primary mapper I could assemble a mapper even from a table missing a primary_key, that's what I thought was the meaning of: "Construct a Mapper that will define only the selection of instances, not their persistence." What I get is: ipdb> mapper(X, table, non_primary=True) *** ArgumentError: Mapper Mapper|lavori_class|lavori|non-primary could not assemble any primary key columns for mapped table 'lavori' So wht's the real meaning of primary_key? thanks sandro *:-) -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
