I am making a action for Google Home. It's about restaurant booking so I have to take some information from users like:
How many guests do you want to book the table for?
For which date?
For which time?
Then I have to store it on Firebase real time database. For the guests parameter it is writing the value to the database but the date and time parameters are not showing on database.
what will be code for storing both time and date with guests in database?
'use strict';
const functions = require('firebase-functions');
const {WebhookClient} = require('dialogflow-fulfillment');
const {Card, Suggestion} = require('dialogflow-fulfillment');
//initialize db connection
const admin = require('firebase-admin');
admin.initializeApp();
process.env.DEBUG = 'dialogflow:debug'; // enables lib debugging statements
exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
const agent = new WebhookClient({ request, response });
console.log('Dialogflow Request headers: ' + JSON.stringify(request.headers));
console.log('Dialogflow Request body: ' + JSON.stringify(request.body));
function welcome(agent) {
agent.add(`Welcome to my agent!`);
}
function fallback(agent) {
agent.add(`I didn't understand`);
agent.add(`I'm sorry, can you try again?`);
}
function createBooking(agent) {
let guests = agent.parameters.guests;
let time = new Date(agent.parameters.time);
let date = new Date(agent.parameters.date);
let bookingDate = new Date(date);
bookingDate.setHours(time.getHours());
bookingDate.setMinutes(time.getMinutes());
let now = new Date();
const guestsParam = agent.parameters.guests;
if (guests < 1){
agent.add('You need to reserve a table for at least one person. Please try again!');
} else if (bookingDate < now){
agent.add(`You can't make a reservation in the past. Please try again!`);
} else if (bookingDate.getFullYear() > now.getFullYear()) {
agent.add(`You can't make a reservation for ${bookingDate.getFullYear()} yet. Please choose a date in ${now.getFullYear()}.`);
} else {
let timezone = parseInt(agent.parameters.time.toString().slice(19,22));
bookingDate.setHours(bookingDate.getHours() + timezone);
agent.add(`You have successfully booked a table for ${guests} guests on ${bookingDate.toString().slice(0,21)}`);
agent.add('See you at the restaurant!');
}
return admin.database().ref('/guests').push({guests: guests}).then((snapshot) => {
console.log('database write successful: ' + snapshot.ref.toString());
});
}
let intentMap = new Map();
intentMap.set('Default Welcome Intent', welcome);
intentMap.set('Default Fallback Intent', fallback);
intentMap.set('restaurant.booking.create', createBooking);
// intentMap.set('your intent name here', yourFunctionHandler);
// intentMap.set('your intent name here', googleAssistantHandler);
agent.handleRequest(intentMap);
});
Well, the simple answer is that you don't see them in the database because you don't put them there.
The line
admin.database().ref('/guests').push({guests: guests})
Just stores a document with the guests. You don't do anything with bookingDate.

I am trying to pass a FirebaseFirestore User Uid to a Stripe / firestore cloud function.
So I would have an https query like following :
https://connect.stripe.com/express/oauth/authorize?response_type=code&client_id={accountid}&scope=read_write to open in a Webview
Here is my function
exports.connectStripeExpressAccount = functions.https.onRequest((req, res) =>{
console.log('query state is ----> ' + req.query.state);
const authCode = req.query.code;
return stripe.oauth.token({
grant_type: 'authorization_code',
code: authCode,
}).then(async response => {
var connected_account_id = response.stripe_user_id;
const uid = req.query.state
const writeResult = await admin.firestore().collection('Registration').doc(uid)
.set({'customer_id': connected_account_id});
return res.send("Well done, account integration is completed. You can now close the window and go back to the app");
});
});
For new integrations with Express Accounts you should ideally be using the Account Links functionality instead of OAuth. That said, if you provide the state value, it should carry through, so I'd make sure you're actually providing it when opening the WebView.
If the User uid is stored in the query parameter state and the URL looks like this:
https://connect.stripe.com/express/oauth/authorize?response_type=code&client_id=ca_JCV8JW9ZIjBaGkwkhbDDDQegceWGidqh&scope=read_write&state=useruidxxx
Your code would look like this:
exports.connectStripeExpressAccount = functions.https.onRequest((req, res) =>{
console.log('query state is ----> ' + req.query.state);
const authCode = req.query.code;
return stripe.oauth.token({
grant_type: 'authorization_code',
code: authCode,
}).then(async response => {
var connected_account_id = response.stripe_user_id;
const uid = req.query.state
const writeResult = await admin.firestore().collection('Registration').doc(uid)
.set({'customer_id': connected_account_id});
return res.send("Well done, account integration is completed. You can now close the window and go back to the app");
});
});
I am trying to get data from multiple intents one by one and then store it in the firebase.
I am contact details from the user.
Main intention is to make the employees and employers get details of each other.
So once stored the data i would search the database and let the other one know the people satisfying their criteria.

I have tried the youtube tutorials but couldn't get anywhere.
It's Confusing how to get values in an array.
Thanks in advance!
I'm doing a chatbot similar to helpdesk (Dialogflow - inline editor). I'm able to write to datastore but I`m facing some issues with read out of data, it is a basic operation of finding UserID but code is not kicking off -please help code below.
const Datastore = require('#google-cloud/datastore');
const datastore = new Datastore({
projectId: 'bot-datastore-mnddjv'
});
function write(agent) {
var name = agent.parameters.name;
var sur = agent.parameters.sur;
var uid = agent.parameters.uid;
const taskKey = datastore.key('Key');
const entity = {
key: taskKey,
data: {
name: name,
sur: sur,
uid: uid
}
};
return datastore.save(entity).then(() => {
console.log(`Saved ${entity.key.name}: ${entity.data.item_name}`);
agent.add(`Stored ${name},${sur}`); -----> That part is working
});
}
function read(agent){
const query = datastore.createQuery('Key').filter('name');
return datastore.runQuery(query).then(() =>{
const sortA = query.order('name');
const sortD = query.order('name',( {descending:true}));
agent.add("Scores: ",sortA); ----// This funcion is not working
});
}
let intentMap = new Map();
intentMap.set('Default Welcome Intent', welcome);
intentMap.set('Default Fallback Intent', fallback);
intentMap.set('Zapis', write);
intentMap.set('Odczyt', read);
agent.handleRequest(intentMap);
});
The issue seems to be in your usage of filter().
You need to use an operator like =, > etc. so if that condition is met the query will run.
Here is a sample code from the documentation.
const query = datastore
.createQuery('Task')
.filter('done', '=', false)
.filter('priority', '>=', 4)
.order('priority', {
descending: true,
});
I am using "firestore" database for my "dialogflow" chat bot which I already created for an online grocery store. The problem is: I want my chatbot to initially ask questions from users to find the proper item title in my database and then return to user by asking 3-4 support relevant questions about that item. the questions must be the item attributes (Brand, color, size...) and will vary from one item to another. so the chatbot will stream down the user to find the best item.
can you please help me to find the answer? I already created the codes but they don't work and I do not know what is wrong with that. If you already created this and have the index.js file, I appreciate to propose me here.
index.js:
'use strict';
const functions = require('firebase-functions');
// Import admin SDK
const admin = require('firebase-admin');
const {
WebhookClient
} = require('dialogflow-fulfillment');
process.env.DEBUG = 'dialogflow:*'; // enables lib debugging statements

// here we get the database in a variable
const db = admin.firestore();
const data = {...};

There are a number of issues with your code as you've shown it that could cause problems reading and writing with the Firestore database.
It looks like you're trying to find an existing collection to write to with the line
const dialogflowAgentRef = db.collection('dialogflow').doc('agent').where('title', '==', title);
but title isn't defined anywhere, which I suspect causes an error. Furthermore, doc() returns a DocumentReference, but there is no where() method in a DocumentReference.
Remember that you need to structure Firestore using alternating collections and documents. So your "firebase" collection can contain a document named "agent", and that document may have subcollections.
When you're trying to read with
const dialogflowAgentDoc = db.collection('dialogflow/agent/rss/channel/item');
You're getting a collection, but then trying to treat it as a document. The comment suggests that you're trying to read a specific doc from this collection (which makes sense), but you're loading that document by a hard-coded string "agent", rather than trying to get the agent from the parameters passed to you from Dialogflow.
Finally - the paths in the read and write sections don't match. Using hard-coded paths are fine when testing, but make sure you're using matching paths and that they reflect the collection/doc/collection/doc/... path requirement.
So in both cases, you might have a reference that looks something like
const docTitle = agent.parameters.title;
const docRef = db.collection('dialogflow').doc(title);
Which, if you have defined a "title" parameter in your Intents in Dialogflow, will use this to reference the doc, which you can then read or write.
thanks for the answer I already changed my database to real time firebase instead of firestore. still having problem with support relevant questions. I want to go to my real time database to find the item by search using "oederByChild" and "equalTo" methods as I found these in people questions and answer in this website. still cannot find and item title through my database child. here is the codes are written:
'use strict';
const functions = require('firebase-functions');

// const ref = db.ref('server/saving-data/fireblog');
exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
const agent = new WebhookClient({
request,

});
console.log('Dialogflow Request headers: ' + JSON.stringify(request.headers));
console.log('Dialogflow Request body: ' + JSON.stringify(request.body));
// Get the database collection 'dialogflow' and document 'agent' and store
// the document {entry: "<value of database entry>"} in the 'agent' document
function writeToDb(agent) {
const databaseEntry = agent.parameters.databaseEntry;
const acc = db.ref('rss/channel/item/4/title'); //**This worked! */
acc.set({
entry: databaseEntry
});
return Promise.resolve('write complete')
.then(_acc => {
agent.add(`Wrote ${databaseEntry} to the realtime database.`);
return false;
}).catch(err => {
console.log(`Error writing to Firestore: ${err}`);
agent.add(`Failed to write "${databaseEntry}" to the Firestore database.`);
});
}
// and this is when we want to write to in the same child, keeping the old values:
//const acc = db.ref('/rss/channel/item/5/color'); //**This worked! */
//const result = acc.child(databaseEntry).set({entry: databaseEntry});
//agent.add(`Wrote ${databaseEntry} to the realtime database.`);
//console.log(result.key);
//});
// to read data
function readFromDb(agent) {
const any = agent.parameters.any;
agent.add(`Thank you...`);
var rootRef = db.ref();
var childref = rootRef.child("rss/channel/item");
return childref.orderByChild("title").equalTo("Icebreaker").once("value").then(function(snapshot){ //has been taken from the bus example: https://stackoverflow.com/questions/51917390/dialogflow-how-do-i-pass-a-parameter-through-in-a-firebase-query

Newbie question: Cloud Function times out every single time I run it.
In addition, it only returns ONE value, which is the first userId, in the Functions Log and none of its children. Im assuming this is because it's calling the .once however, it's in a forEach loop, so I'm not sure what it wants.
Firebase database
-items
---- userId0123456789
---- randomKey987654321
-- itemName
-- itemDate
-- itemType
---- userId987654321
---- randomKey012345678
-- itemName
-- itemDate
-- itemType
And here is the function code...
const key = req.query.key;
**let userID = 'xxxxx';
let ikey = 'xxx';**
var dbRef = admin.database().ref('/items/{userID}/{ikey}');
dbRef.once("value", function(snapshot) {
snapshot.forEach(function(child) {
console.log(child.key+": "+child.val());
});
});
UPDATE: here is the entire function and now it's just timing out with no response.

Help is much appreciated.
Update:. Timeout is fixed and it returns the userId's that are in the database under "/items". HOWEVER, if I use ${userId}/${key} I get nothing. I'm still not able to tell how to get the children under random userId's in the database and none of the other posts I read explain it. Firebase's docs state to use {userId} to get all under that wildcard but its not working. What am I missing?
You're not returning the result of the once function or returning at all, so the function doesn't know when to finish hence the timeout.
let userID = 'xxxxxxxxx';
let key = 'xxxxxxxx';
let ref = admin.database().ref(`/items/${userID}/${key}`);
return ref.once("value", function(snapshot) {
snapshot.forEach(function(child) {
console.log(`${child.key}: ${child.val()}`);
});
});
Also please be aware that the reference you are observing will give you the children of a particular user item (itemName, itemDate, itemType). If you want the items belonging to a particular user, adjust your reference path to be /items/${userID}.
When inside a HTTP trigger, you can send a response after observing the value.
exports.CheckItemTypeinFB = functions.https.onRequest((req, res) => {
...
ref.once("value", function(snapshot) {
snapshot.forEach(function(child) {
console.log(`${child.key}: ${child.val()}`);
});
res.send(200, {/* response data */});
});
});
