i have a product with many images relationship in database. Now i can
enter the images by its form separately. and then in a dropdown in
Product i select it. But i want to insert the product and the image at
the same time save its name in database and upload it. i tried binding
product to images and i get xception: Mapped instances to be bound
must either have a primary key set or not be in a Session. When
creating a new object, bind the class instead [i.e., bind(User), not
bind(User())]. . not sure why. at least some ideas normally how its
done. thanks.

Isn't the error message explicit ? Try to add session=dbsession when
binding instances
