Re: [sqlalchemy] Modification tracking
In an application, I have rather elaborate needs to track changes. Now I need to track all modifications to all fields, including the relationship list objects. One way to accomplish this would be within the database server itself. With a rule that, instead of updating a record, inserts a new one (and updates a version column).

Putting aside the not recommended idiom of *redefining* a symbol in that way, you should import/define the session maker function from somewhere before you can use it. As said, I'd recommend using different names, to avoid confusion, for example session = SessionMaker() hth, ciao, lele. -- nickname: Lele Gaifax | Quando vivrò di quello che ho pensato ieri real: Emanuele Gaifas | comincerò ad aver paura di chi mi copia. l...@metapensiero.it | -- Fortunato Depero, 1929. -- You received this message because you are subscribed to the Google Groups sqlalchemy group.
