Suppose there are multiple child, in that case, the data structure will change slightly. It will be something like this: data |_ 1 |_ first_name: Rahul |_ last_name: Sharma |_2 |_first_name: XYZ |_last_name: ABC You need something unique like ID (Here I used 1, 2 etc but you can use username, email or anything which is unique) to uniquely identify a record. Then the code to write into the database should be something like: return admin.database().ref("data").child(ID).set({ first_name: res.data.first_name, last_name: res.data.last_name }); Where ID can be 1, 2, 3.. and so on.... And code to read from database should be something like: return admin.database().ref("data").once("value").then((snapshot) => { const value = snapshot.child(ID).val(); const first_name = value.first_name; }
@@AxleWebTechnologies Thanks man! I was stuck in this part for a while. Your video helped me a lot. Can you please post a video on how to access Firebase cloud functions using fulfilment. I have a JSON file in the Cloud function but I'm not able to access it in Dialogflow. Please help me with this.
@@sivakarthick2924 Glad you find it useful. Will create a video on accessing Firebase cloud functions soon. Please subscribe and press the bell icon to get the updates.
Probably something wrong with the format in which you are storing your data in firebase. Have a look here: stackoverflow.com/questions/43196547/firebase-unable-to-access-data-with-snapshot
Thank you very much Sir for posting this, but when I click on enable inline editor in fulfillments it asks to manage billing and a billing account. whereas in this video you weren't asked to enable billing? Have you already enabled billing and does it charge when we connect it to firebase?
hi, I have developed the chatbot in dialogflow (which is for diabetes patients), so now I need to save data. so for that should I need to write the same code as you wrote. plsss replyyyy
Hi Kamalpreet, you dont need to write the same code. The code you will write depends on what you want to achieve. If you need any help, please drop me an email at anshul.shrivastava@axlewebtech.com
function readdb(agent) { const mobileno=agent.parameters.text; return admin.database().ref('data').transaction((data) => { const mobileno=agent.parameters.text; let mob=data.mobile; let bal=data.balance; if(mobileno==mob) { agent.add(`Your account balance is`+bal); } else { agent.add(`not register`); } return data; } ); Firebase DB data is parent child is mobile no & balance now in that i have multiple mobile no and each no have different balance then how it work?

I receive this warning which I suspect is why I cannot access the database:"Warning, FIREBASE_CONFIG environment variable is missing. Initializing firebase-admin will fail",
Yes, you can do that by using Custom Webhook option (Fulfillment > Webhook) However, you need to keep in mind that you have to setup your own web server which can accept POST requests in order to get this working.

yes definitely, sessionId depends on which platform you are using for e.g. facebook, slack etc. Check the response format for corresponding platform and then save it in firebase database.

@@AxleWebTechnologies can't paste all here. so here is a section. As you can see the function for name and age as exactly the same. but age is getting stored, but name isn't.

Hy there, i have seen your video. I have problem nowdays dialogflow use Api V 2.0, how i solve this problem, i check in raw api response this "message": "Webhook call failed. Error: DEADLINE_EXCEEDED."
This is due to webhook taking more than 5 seconds to respond. Please don't perform heavy operations on webhook which might take more than 5 seconds to respond.
Muchas gracias, estuve buscando esto por la red durante varios días y no entendía nada hasta que acabo de ver tu vídeo. Ya me suscribo a tu canal y de nuevo gracias!
I want to call external Rest Api(cloud application along with the Body ,Custom Header,Authentication) and want to get response in the chat from dialogflow ,any leads on it will be appreciated.
Yes, you can do that using axios library. Following link might help you: stackoverflow.com/questions/44617825/passing-headers-with-axios-post-request PS: Make sure to Enable billing account otherwise Dialogflow can't connect to external network.
Thanks for sharing the video. It is really useful .Although i followed the same steps , there are no errors but my values are NULL. I am not sure what is causing the problem.Please help me out .dialogflow.cloud.google.com/#/agent/avg-project-ombxgx/
It is difficult to tell the error without seeing the code. There are couple of things you can check 1. Make sure billing account is enabled 2. Make sure fulfillment is enabled in the intent 3. Make sure you can see some logs in the console.logs.
Hey Anshul, at 13:11 I accidentally pressed the "Add" button and my "data-first_name" disappeared. Did I save this in the database? Could that cause problem down the line?
Did you publish your code for the fulfillment somewhere? I can't get my code to work and I know that there is a simple syntax that I missed. I got the write to work fine, but I can't get reading to work properly.
Yes here it is: Connect Dialogflow with MySQL gist.github.com/Anshul0305/aace32e8eabcb2ef49835d0079091e00 Connect Dialogflow with Spreadsheets gist.github.com/Anshul0305/0af703a063f51ca00213add2634cd88b Connect Dialogflow with External APIs gist.github.com/Anshul0305/405e050cf438975baec8a746ffda9991
5:12 I'm a little confused. Are the training phases the same regardless of how the database is used? Asking because we have an project at our college about creating a voicebot for a restaurant. We want it to work so that people can order pizzas without calling real people.
I cant even enable the inline editor it shows this: Cloud Functions integration requires billing to be set up (more info on pricing and usage here: cloud.google.com/functions/pricing). Please go to Google Cloud Console to set up billing first.
Yes, you have to setup billing account for that. Please watch our video on how to connect Dialogflow with external APIs. In that we have explained how to enable billing account.
Hey! Will this work even if I have intents as a follow up? Because I tried this but it is not showing the changes though getting deployed without any error
Yes this should work. Make sure to enable fulfillment in your follow up intents, also in your code, make sure to write the correct code for the intent map.
How we can build a Chatbot like Google home for only one category and fetch Realtime data from database. Also please make video on how to deploy this Chatbot in android studio.
You can use Dialogflow for building Google home chatbot. They call it actions on Google. Visit developers.google.com/actions/ for more details. Android studio is for building apps for Android OS. I would recommend using Visual Studio Code for chatbot coding.

Why does the data get overwritten all the time. I need to use this approach but need to find a way to store data from multiple users without overwriting them. Please help
how we can store information of many number of people in firebase database? is there an option that, we can create automatically generating tree in firebase?
There is no specific reason. Both are great. In some projects we have used cloud firestore as well. The choice depends on your use case. Please refer to this link for more details: firebase.google.com/docs/database/rtdb-vs-firestore

Hi Ashish, you need to use backtick in the below code agent.add('The value from database is ${value}'); so it should be something like this: agent.add(`The value from database is ${value}`);
hi, buddy, may I ask you a favor? I followed the vedio , Writing data feature is OK, but READ DATA feature has been wroten many time. hope you can introduce more knowledge about it.
Suppose there are multiple child, in that case, the data structure will change slightly. It will be something like this: data |_ 1 |_ first_name: Rahul |_ last_name: Sharma |_2 |_first_name: XYZ |_last_name: ABC You need something unique like ID (Here I used 1, 2 etc but you can use username, email or anything which is unique) to uniquely identify a record. Then the code to write into the database should be something like: return admin.database().ref("data").child(ID).set({ first_name: res.data.first_name, last_name: res.data.last_name }); Where ID can be 1, 2, 3.. and so on.... And code to read from database should be something like: return admin.database().ref("data").once("value").then((snapshot) => { const value = snapshot.child(ID).val(); const first_name = value.first_name; }

Hello, again! Do you have something on Yes and No answers? I searched but I couldn't find it. The problem I'm facing is that a lot of interactions have Yes and No flows, but the bot is mixing them. Or if I have same single words (even if they are in different entities and diferent intents) i gets mixed. I'm not sure if it is something in the contexts, the lifespam, the followup intent or any other issue. If the user answers with a simple yes or no, it gets mixed. If they say "yes I use paypal" it gets right. But in real use case I cannot demand a complete answer. Any tips? Thank you so much!
Ok, here is what you can do. Let's say you have an intent "Use Paypal". When you ask a question, "Would you like to use Paypal", set an output context, "use-paypal" in that intent. Now create two more intents named "Use Paypal - Yes" and "Use Paypal - No" In "Use Paypal - Yes", input context should be "use-paypal" and training phrases should be "Yes, yeah" etc In "Use Paypal - No", input context should again be "use-paypal" but training phrases should be "No,nope" etc and then in both intents Use paypal - yes and no, you can write corresponding response in the response section. You can watch my video on contexts and follow up intents here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kIlZ8FgNVx0.html
Hi Axle, thanks for the tutorial, really helpful and educational. Is there a way to connect a Dialogflow Agent to an Oracle Database. If so may you please share how it can be done. Thanks
Hey!! Tks so much for this video! I managed to go to the point of writing the first parameter in the database. But when I set the second one, the first one is erased from the database. (the first parameter turns red in firebase and the last one turns green) This is the code: function handleCompanyName(agent){ const text = agent.parameters.companyname; return admin.database().ref('data').set({ companyname: text }); } function handleAccountingType(agent){ const text = agent.parameters.accountingtype; return admin.database().ref('data').set({ accountingtype: text }); } let intentMap = new Map(); intentMap.set('welcome', welcome); intentMap.set('Default Fallback Intent', fallback); intentMap.set('company.name', handleCompanyName); intentMap.set('accounting.type', handleAccountingType); agent.handleRequest(intentMap); }); I'll have to do this for around 30 parameters, so I'm kind of lost on how to follow as is not working from the second one. The second question is that for some other intents I have up to 5 different parameters. For example, I have an Onboarding preferences intent, and I ask for datastart (using @sys.date) and financialswhen (using one entity I created called @financials-when). As they are all under one Intent I couldn't understand how to write this code. Thanks in advance for your help!
Hello Rosana, Please see my pinned comment. You need to use ref("data").child(ID).set() Where ID is a unique ID of each entry in the database. Feel free to comment back if you still have any questions.
@@AxleWebTechnologies yes, is working. Now the code is like: function saveCompanyName(agent){ const companyname = agent.parameters.companyname; return admin.database().ref('data').child('company name').set({ companyname: companyname }); } And the database is like: data accounting type accountingtype: "Quarterly" company name companyname: "Apple" :) I'm not sure if for the ID is better to use a number or a name as I'm doing now. But I can change later on if necessary. Now I'll try the multiple entries from one intent and let you know if successful or if I have more questions. Thanks a lot!
@@AxleWebTechnologies Also done with more than one parameter from a unique Intent. Code that worked: function saveStartandOnboardingDate(agent){ const datastart = agent.parameters.datastart; const financialswhen = agent.parameters.financialswhen; return admin.database().ref('data').child('start and onboarding').set({ datastart: datastart, financialswhen: financialswhen }); } Thaaaanks!

hi @Axle Web Technologies! i already have integrated my dialog flow with firebase database but the problem is that the values in my child nodes updates itself automatically with the values that i had stored previously.
