ndbviewer 0.0.3

This module allows you to view local data from your Google Cloud NDB projects using thee Google Datastore Emulator.

Step 1: To your existing code add:
import mock from flask import Flask from google.cloud import ndb import google.auth.credentials import os

    os.environ["DATASTORE_DATASET"] = "test"
    os.environ["DATASTORE_EMULATOR_HOST"] = "127.0.0.1:8001"
    os.environ["DATASTORE_EMULATOR_HOST_PATH"] = "127.0.0.1:8001/datastore"
    os.environ["DATASTORE_HOST"] = "http://127.0.0.1:8001"
    os.environ["DATASTORE_PROJECT_ID"] = "test"
    
    credentials = mock.Mock(spec=google.auth.credentials.Credentials)

step 1.5 Anywhere you want to test the database add: client = ndb.Client(project="test", credentials=credentials) with client.context():

Alternatively you can use the example project at https://github.com/ReddingSoftware/Google_NDB_Emulator

Step 2: Install google cloud SDK if you haven't already done so https://cloud.google.com/sdk/docs/install

Step3: After navigating to your project folder in your terminal run:

gcloud components install cloud-datastore-emulator

(if you want more on datastore-emulator go to https://cloud.google.com/datastore/docs/tools/datastore-emulator)

Step 4: in your terminal run: pip install ndbviewer

Step 5: add the requirements.txt info to your current requirements.txt and in your terminal run: pip install -r requirements.txt

Step 6: in your terminal run: gcloud beta emulators datastore start --data-dir=. --project test --host-port "127.0.0.1:8001"

Step 7: Open a new terminal but leave the emulator terminal running. This can be done in visual studio code by clicking the plus sign on choosing Terminal and New Terminal.

Step8: Make sure you are still navigated to the NDBEmulator folder in your terminal.

Step 9: in your new terminal run: For mac: export FLASK_APP=main (press return) export FLASK_ENV=development (press return) flask run For PC: set FLASK_APP=main (press return) set FLASK_ENV=development (press return) flask run

 Alternatively, you can run:
    python3 main.py

 or just

    python main.py

Step 10: in your browser go to http://127.0.0.1:5000 (you'll see the main page)

Step 11: add data to your test database. If you don't know how to add data you can use the example project at https://github.com/ReddingSoftware/Google_NDB_Emulator

step12: in your browser go to http://127.0.0.1:5000/ndbviewer

step13: Choose the ndb Kind that you want to view
