Using the models below, on trying to create a Product with no
ProductVersions existing, the form fails validation with "Missing Value"
against the Versions entry.
class Product(DeclarativeBase):
__tablename__ = 'products'
#{ Columns
id = Column(Integer, primary_key=True)
name = Column(Unicode(128), nullable=False)
description = Column(Unicode(1024), nullable=False)
created = Column(DateTime, default=datetime.now)
#}
class ProductVersion(DeclarativeBase):
__tablename__ = 'product_versions'
#{ Columns
id = Column(Integer, primary_key=True)
version_label = Column(Unicode(128), nullable=False)
resource_location = Column(Unicode(1024), nullable=False)
created = Column(DateTime, default=datetime.now)
product_id = Column(Integer, ForeignKey('products.id'))
product = relation(Product, backref=backref('versions', order_by=id))
