If I have two types of models that each reference each other, whichever one I try to define first says it does not recognize the referenced other type (because it is defined further down in the file). For example:
class Author(db.Model):
most_recent_book = db.ReferenceProperty(Book)
class Book(db.Model):
author = db.ReferenceProperty(Author)
This will claim that the referenced "Book" model is not recognized. If I flip the order, I run into the same issue (except it will say that "Author" is not recognized). How do I get around this?
