There are three separate demos:

• app: a Google App Engine application with a set of example uses
• shell: an application that sets up the ndb environment then opens up a python shell for you to interact with.
• task_list: a basic application which runs inside Compute Engine.

This demo shows various ways to use ndb. The application consists of serveral different handlers.

• hello.py: a simple hello world application.
• guestbook.py: a simple guestbook application.
• dataviewer.py: a page that allows you to query for entities in your Datastore using ndb GQL.
• main.py: home page and user handling including login/logout.
• fibo.py: calculate the fibonacci sequence, taking advantage of ndb tasklets.

This folder also has a demo for using ndb from outside of App Engine. You can use shell.py to interact with your Datastore using ndb through the Cloud Datastore API.

1. Copy ndb (the entire folder) into the demo subdirectory.

2. Deploy the demo application using the command:

       gcloud app deploy demo/app.yaml
   

   This will deploy the app to your default project, which you can configure using gcloud:

       gcloud config set project <project-id>
   

1. Follow the instructions below to setup ndb in GCE.

2. Run the shell. From here you can write ndb code to interact with Datastore. Don't forget, this shell is interacting with the production Datastore of your .

       python demo/shell.py
   

1. Follow the instructions below to setup ndb in GCE.

2. Run the task list application. Don't forget, this application is interacting with the production Datastore of your .

       python demo/task_list.py
   

1. Install pip

       sudo apt-get update
       sudo apt-get install python-pip
   

2. Install the Google App Engine SDK and point ndb to the installation. If you installed gcloud to a different location then your App Engine SDK may be installed in a different location.

       sudo gcloud components install app-engine-python
       export GAE=/usr/local/share/google/google-cloud-sdk/platform/google_appengine
   

3. Install ndb

       pip install --pre ndb
   

4. Setup your environment.

       export DATASTORE_PROJECT_ID=<project-id>
       export DATASTORE_USE_PROJECT_ID_AS_APP_ID=true
   

5. Finally, make sure you have authenticated using gcloud.

       gcloud auth login
