The source code for the library (and demo code) lives on GitHub, You can install the library quickly with pip:

$ pip install gcloud

In order to run the demo, you need to have registred an actual gcloud project and so you'll need to provide some environment variables to facilitate authentication to your project:

• GCLOUD_TESTS_PROJECT_ID: Developers Console project ID (e.g. bamboo-shift-455).
• GCLOUD_TESTS_DATASET_ID: The name of the dataset your tests connect to. This is typically the same as GCLOUD_TESTS_PROJECT_ID.
• GOOGLE_APPLICATION_CREDENTIALS: The path to a JSON key file; see regression/app_credentials.json.sample as an example. Such a file can be downloaded directly from the developer's console by clicking "Generate new JSON key". See private key docs for more details.

Run the example script included in the package:

$ python -m gcloud.datastore.demo

And that's it! You just read and wrote a bunch of data to the Cloud Datastore.

You can interact with a demo dataset in a Python interactive shell.

Start by importing the demo module and instantiating the demo dataset:

>>> from gcloud.datastore import demo
>>> dataset = demo.get_dataset()

Once you have the dataset, you can create entities and save them:

>>> dataset.query('MyExampleKind').fetch()
[<Entity{...}, ]
>>> entity = dataset.entity('Person')
>>> entity['name'] = 'Your name'
>>> entity['age'] = 25
>>> entity.save()
>>> dataset.query('Person').fetch()
[<Entity{...} {'name': 'Your name', 'age': 25}>]

>>> from gcloud import datastore
>>> from gcloud.datastore import demo
>>> dataset = datastore.get_dataset(demo.DATASET_ID)
