Hallo, I read up the solution for implementing 1:n relationships by placing a ReferenceProperty on the "n" part and naming the collection_name the name you want to appear in the "1" part.
I have a datamodel with hierarchical inheritance. For Some Element D I want to have a 1:n relationship to a more generic type (and its subclasses) A. So I have to put a ReferenceProperty to A naming D as the type beeing referenced. This doesn't work because D has not been defined when its named as a type for the reference in A. I can't put the definition of D in front of A because the superclass of D has not been defined then (or is A, to keep it simple). Is there any solution for my problem? In Java, I would declare D prior to using it in A, but define it at its appropriate place. I don't know if there is a sulotion in an interpreted language....
