How to load data using key_name by the Google App Engine downloader

I can load data, but key_name is empty. How can I use id in CSV as the key_name in the data store?

I like to use "id" as key_name because other data uses "id" as a foreign key. I am new to Google App Engine.

This is CSV data.

"id","name"
"1","USA"
"2","France"
"3","Italy"

This is yaml

- model: model.testcountry.TestCountry
  connector: csv
  connector_options:
    encoding: utf-8
    columns: from_header
  property_map:
    - property: __key__
      external_name: id
    - property: name
      external_name: name

PS: I'm trying to upload data to a local environment.

Update

Thanks for the help, I tried the code, but it does not work. The result is strange.

In the terminal window, a log message tells me that the download completed successfully, however I can not find any entries in the Google App Engine console (http: // localhost: 8080 / _ah / admin / datastore). The data store is empty, there is no record.

appcfg.py upload_data --config_file=bulkloader.yaml --filename=testcountries.csv --kind=TestCountry --url=http://localhost:8080/remote_api --num_thread=1
