Question

在尝试创建运行以下命令的bulkloader.yaml时，我收到了0个实体：

appengine create_bulkloader_config --filename=bulkloader.yaml --url=https://dev-dot-mysite.appengine.com/_ah/remote_api

在我的app.yaml中，我已配置_ah

- url: /_ah/remote_api
  script: $PYTHON_LIB/google/appengine/ext/remote_api/handler.py
  login: admin
  secure: always

- url: /.*
  script: ...

我得到了以下内容。

02:01 PM Creating bulkloader configuration.

当我打开bulkloader.yaml时，我看到：

# Autogenerated bulkloader.yaml file.
# You must edit this file before using it. TODO: Remove this line when done.
# At a minimum address the items marked with TODO:
#  * Fill in connector and connector_options
#  * Review the property_map.
#    - Ensure the 'external_name' matches the name of your CSV column,
#      XML tag, etc.
#    - Check that __key__ property is what you want. Its value will become
#      the key name on import, and on export the value will be the Key
#      object.  If you would like automatic key generation on import and
#      omitting the key on export, you can remove the entire __key__
#      property from the property map.

# If you have module(s) with your model classes, add them here. Also
# change the kind properties to model_class.

可能出现什么问题？

谢谢！

Bulkloader实体是根据定期生成的“数据存储统计”创建的。如果您查看应用管理控制台，将会有一个部分。如果不存在统计信息，则不会生成任何实体。

在开发服务器上，您可以强制立即生成统计信息，但在生产时，我不确定是否有其他方法可以立即强制执行

创建批量loader.yaml时创建的0个实体
