I'm trying to get a certain access pattern to work and I need a bit of help:
https://gist.github.com/deontologician/5922496 What I'm trying to do is use an association proxy to create a view of a collection that looks like a list of dictionaries (for serializing to json). I also want to update that collection y receiving one of these dictionaries from the user. The problem is, I have to also keep two fields in sync that the users "shouldn't see". In the example, it's widget_id and machine_id. widget_id is easy, because it's the foreign key to the owner of the collection, so sqlalchemy sets that for me. The problem is that the machine_id needs to be kept in sync as well, but it refers to an object "one level up". I've tried adding a validator to the collection under the proxy, but it only checks on append, so initially null fields that the server sets aren't handled the way SQLA handles the foreign_key field. Is there an easier way to sync up the Gadget's machine_id field with the Widget's machine_id field than just having a listener for every set event on machine_id go through the entire collection and set it on all the objects? -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
