          cls.engine.table = storage_models[0]
docs: Remember: Distributed table does not store any data, just provides distributed access to it.
  
          So if we define a model with engine that has no defined table for data storage
          (see FooDistributed below), that table cannot be successfully created.
          This routine can automatically fix engine's storage table by finding the first
          non-distributed model among your model's superclasses.
  
          >>> class Foo(Model):
          ...     id = UInt8Field(1)
          ...
          >>> class FooDistributed(Foo, DistributedModel):
          ...     engine = Distributed('my_cluster')
          ...
          >>> FooDistributed.engine.table
          None
          >>> FooDistributed.fix_engine()
          >>> FooDistributed.engine.table
          <class '__main__.Foo'>
  
          However if you prefer more explicit way of doing things,
          you can always mention the Foo model twice without bothering with any fixes:
  
          >>> class FooDistributedVerbose(Foo, DistributedModel):
          ...     engine = Distributed('my_cluster', Foo)
          >>> FooDistributedVerbose.engine.table
          <class '__main__.Foo'>
