Thanks for posting your code sample and your solution. In fact you got it right, Datastore Entity ancestor paths [1] are designed to allow entities to optionally be assigned parents. Meaning that upon creation of a datastore entity, the ancestor path of this entity has to be specified explicitly in order to be part of the same entity group.
If possible, it would be great if you could let the community know whether your proposed solution worked for you.
