GAE ndb put() argument error

I am trying to save an object to GAE's datastore. When doing this I am getting the error:

Traceback (most recent call last):
  File "/Users/Soderstrom/google-cloud-sdk/.install/.backup/platform/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/runtime/wsgi.py", line 267, in Handle

  File "/Users/Soderstrom/PycharmProjects/MyApp/main.py", line 559, in backends
    db.save(v.getFastigheter(), '1')
TypeError: put() takes exactly 1 argument (2 given)

This is independent of the actual amount of arguments passed to the entity creator. 

db.save(v.getSomeData(), '1')     <- main.py, line 559
db.load('1')

This is the db module:

class ndbc(ndb.Model):
    val = ndb.PickleProperty(compressed=True, indexed=False)
    key_name = ndb.PickleProperty(indexed=True)

    @classmethod
    def set(cls, key_t, val_t):
        entity = cls(val=val, key_name=key)

        entity.put()
        return val_t


    def save(obj, name):
    return ndbc.set(name, obj)

Don't you mean entity = cls(val=val_t, key_name=key_t)? Also, key_name is an old db property. For ndb, you should use id:

https://docs.google.com/document/d/1AefylbadN456_Z7BZOpZEXDq8cR8LYu7QgI7bt5V0Iw/mobilebasic

Not sure id can be a PickleProperty. Interested to see if this works.
