'Query' object has no attribute 'kind' when using appcfg.py download_data

问题

I'm having problems with bulk downloads -- all of my data is not being pulled down.

I'm still debugging, but I see in my console:

Traceback (most recent call last):
File "/Users/matthew/local/opt/google_appengine/google/appengine/tools/adaptive_thread_pool.py", line 150, in WorkOnItems
  status, instruction = item.PerformWork(self.__thread_pool)

  transfer_time = self._TransferItem(thread_pool)

  download_result = self.request_manager.GetEntities(self)

  query = self.filter_datastore_query(query)
File "/Users/matthew/local/opt/google_appengine/google/appengine/ext/key_range/__init__.py", line 175, in filter_datastore_query
  return EmptyDatastoreQuery(query.kind)
AttributeError: 'Query' object has no attribute 'kind'

.....[ERROR   ] Error in Thread-7: 'Query' object has no attribute 'kind'

[INFO    ] Have 83 entities, 0 previously transferred
[INFO    ] 83 entities (0 bytes) transferred in 2.5 seconds

Any ideas? For this test, I'm only exporting data for a single Model, but each record does have 2 references to another Model.

回答1:

It looks like you've encountered a bug in the bulk downloader, unfortunately. Can you please file a bug report here? It'd help if you can supply the model definition and bulk loader exporter subclass definition.
