Hi, I've been playing around with SA for about a week now and need a custom ORM.
The datatype that will hold all data is essentially a modified dictionary - the key of the dictionary (may be a tuple) is the key in the database and the list associated is the rest of the row. However, some of the elements in the list may itself be a modified dictionary as well. Essentially you have a tree-like structure of dictionaries within dictionaries. There will be information in the dictionary structure to resolve foreign key constraints. Basically all transactions will return this mod. dict and will then need to write it back to a db. Looking at the current orm, I'd have to define classes separately and create relations between them for each top-level dictionary. I don't want to do that - I don't want to re- define the whole session and UOWTransaction classes either. Is there a way I can modify the session/UOWTransaction classes to pick up the dependencies from the dictionaries and proceed as before without defining any mappers? I don't mind changing the code (with some guidance). Thanks. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
