python - How can I get the ndb.Model when my only input is an ndb.Query?

Question

Let's say there is ndb.Model that looks like this:

class Foo(ndb.Model):
  bar = ndb.StringProperty()

My question is, if my only input is the Foo.query() how can I get the model as an object that this query belongs to?

def query_to_model(query):
  # some magic 
  return model

---

The Foo.query().kind return the model's name as a string, but I didn't manage to find a way to get it as an object.

The following works using eval, but only when the model is defined in the same file:

def query_to_model(query):
  return eval(query.kind)

I want something more general than that.
