Hi All,
This is my first post to the group though I've been lurking for a while trying to absorb as much information as I can and I think I've finally hit a wall. I have a data entry-ish type system whose goal is to be flexible in terms of the data it manages, for example, if a new table or columns need to be added to the application adjusting some config data in the app is all that is needed to get it working in the app. This was written in C# and consequently some decisions were made that make it less flexible than it claims to be. So , I'm seeing how far I can get with it in python ,sqlalchemy and wxpython. Right now, I have some wxpython code that can take a mapped class, and map form controls to it for an easily generated data entry form for that class. The next step would be handling the foreign keys and this is where I'm stuck. Given a mapped class how would I derive the relations and the corresponding objects. if I iterate through mapped_class.c.self.props.items() I get either columns or LazyLoaders thus far, if I have a LazyLoader is there a way to pull out the type of mapped class it is associated with? I'm thinking that with this information I need to generate a dropdown that's bound to a list of those guys for example, but the lazyloader doesn't seem to want to give this information up, or I'm severely misunderstanding something, or I completely missed the easy way to do it. And with that, I put myself at the mercy of the list :) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
