[help-wanted] Problem with save method: Saving doesn't do anything

Updated to node v6.9.1 and now I get this error:

Hi,
I can't spot the error so let me write how it "should" work and see from there.
You need node > 4 (so 6.9.1 is perfect)

// server.js
// This is your main starting file
var datastore = require('@google-cloud/datastore')({
    projectId: 'tttttttt',
    keyFilename: './keyfile.json'
});

var gstore = require('gstore-node');
gstore.connect(datastore);

// ... rest of your initial setup

// client-app.model.js

var gstore = require('gstore-node');
var uuid = require('uuid');
var Schema = gstore.Schema;

var schema = new Schema({
    appName: {
        type: 'string',
        required: true,
        read: false
    },
    androidBundleId: {
        type: 'string',
        required: true,
        read: false
    },
    iosBundleId: {
        type: 'string',
        required: true,
        read: false
    },
    modified: {
        type: 'boolean',
        default: false,
        read: false,
        write: false
    },
    createdOn: {
        type: 'datetime',
        default: gstore.defaultValues.NOW,
        write: false,
        read: false
    },
    appKey: {
        type: 'string',
        default: uuid.v4(), // careful as this value will be "static" for all instance. I will add a fix to that soon
        write: false
    }
});

schema.virtual('timestamp').get(function() {
    // the scope (this) is the entityData object
    return this.createdOn;
});

var ClientAppModel = gstore.model('ClientApp', schema); // don't suffix "Model" to the entity kind.

module.exports = ClientAppModel;

// client-app.controller.js
var ClientAppModel = require('../models/client-app.model.js');

function create(req, res) {
    var data = ClientAppModel.sanitize(req.body);
    var clientApp = new ClientAppModel(data, data.appName);
    delete data.appName; // You probably don't need it anymore as it is now the 'id'

    clientApp.save().then(function() {
        res.json(this.plain());
    }).catch((err) => {
        console.log(err);
        res.status(400).json(err);
    });
}

module.exports = {
    create: create
};

Same problem.

Do you want me do do something else?

If I do a:

console.log(clientapp.entityData)

I got this, isn't there something strange?

I have been following all the the steps.

{ appName: 'Yikes',
 androidBundleId: 'com.yikes.android',
 iosBundleId: 'com.yikes.ios',
 modified: false,
 createdOn: 2016-12-02T19:41:49.885Z,
 appKey: '51a22620-92b3-4c21-8125-0c6e7b3b98c0',
 undefined:
  Key {
    namespace: undefined,
    name: 'Yikes',
    kind: 'ClientApp',
    path: [Getter] } }

Thanks in advance.

Where do you do this console.log? If you did it inside the resolve of the Promise, it means that it did work and the entity should be saved in the datastore.

Also, have you tried saving a 'ClientApp' entity without gstore-node? Like in the example here: https://github.com/GoogleCloudPlatform/google-cloud-node#preview-2 to make sure your settings are ok.

Found the problem. The problem was that I had installed an older version of google datastore and I installed on top gstore-node. After I removed the older version everything worked perfect.
Probably because I started with one of the GoogleCloudPlatform/nodejs-docs-samples that had an older version. My bad.

Thanks for the fast support.
Happy to help around here.

Great, happy you found the solution.

PS: just one thing about your example. For now, gstore does not "render" what is set in the "default" value. I will add this feature soon. So your default to uuid.v4() will be the same value for all your entities... If you want this, great, otherwise for now you have to manually set it before saving.
