I have tried this code, but still it is creating entity as class name (*
DynamicEntity*) not as given my custom entity name(*MyCustomEntity*):
class DynamicEntity(db.Expando):
@classmethod
def _get_kind(cls):
return 'MyCustomEntity'
newEntity = DynamicEntity()
newEntity.fname = "Test"
newEntity.put()
