Re : Nested model canjs

I understood some part of that, but the basic problem with nested model is that, when I am creating a new library, at that time i want to tell the server for a new library creation, and the posted data would be an instance of library Model, but I need to post this data into College model,

So, if I call created model or save functions on that model instance, then those are going to Library Model, that's fine, but then after I need to update that data to to server through college Model,

Please help me, if you got a solution for this.

Thanks,

Dj.
