This was already asked here, but it seems that the old methods (example and example) no longer work on Rails 6 because you cannot use App.channel inside your app/javascript/channels/your_channel.js.
Though, correct me if I'm wrong because I'm new to Rails.
My question is: how to disconnect or/and unsubscribe from client side on Rails 6?
I'm especially interested in the "on page change" scenario.
The solution was to save the subscription on a this variable and do the remove call if this variable is not null when page loads, then do the new subscription.
// File: app/javascript/channels/your_channel.js
import consumer from "./consumer";
$(document).on('turbolinks:load', function() {
if (this.subscription) {
consumer.subscriptions.remove(this.subscription);
console.log("unsubing");
}
if ($('#hashtag').attr('data-hashtag-id')) {
var subscription = consumer.subscriptions.create({channel: "TweetsChannel", id: $('#hashtag').attr('data-hashtag-id')}, {
connected() {
console.log("we are live on: " + $('#hashtag').attr('data-hashtag-id'));
},
disconnected() {
console.log("disconecting")
},
received(data) {
$('#tweets-card').prepend(data.content)
}
});
this.subscription = subscription;
}
});
Based on what you shared with us, I imagine you are trying to remove a subscription. You can remove it using consumer.subscriptions.remove [1].
Could you share the snippet of code you have in your app/javascript/channels/your_channel.js?

I Created a android app in which if a press a button and value changes in Firebase database (0/1) , i want to do this using google assistant, please help me out, i searched out but didn't found any relevant guide please help me out
The code to do this is fairly straightforward - in your webhook fulfillment you'll need a Firebase database object, which I call fbdb below. In your Intent handler, you'll get a reference to the location you want to change and make the change.
In Javascript, this might look something like this:
app.intent('value.update', conv => {
var newValue = conv.prameters.value;
var ref = fbdb.ref('path/to/value');
return ref.set(newValue)
.then(result => {
return conv.ask(`Ok, I've set it to ${newValue}, what do you want to do now?`);
})
.catch(err => {
console.error( err );
return conv.close('I had a problem with the database. Try again later.');
});
return
});
The real problem you have is what user you want to use to do the update. You can do this with an admin-level connection, which can give you broad access beyond what your security rules allow. Consult the authentication guides and be careful.
I am actually working on a project using Dialogflow webhook and integrated Firebase database. To make this posible you have to use the fulfilment on JSON format ( you cant call firebasedatabase in the way you are doing)
Here is an example to call firebase database and display a simple text on a function.
First you have to take the variable from the json.. its something loike this (on my case, it depends on your Entity Name, in my case it was "tema")
var concepto = request.body.queryResult.parameters.tema;
and then in your function:
'Sample': () => {
db.child(variable).child("DESCRIP").once('value', snap => {
var descript = snap.val(); //firebasedata
let responseToUser = {
"fulfillmentMessages": [
{ //RESPONSE FOR WEB PLATFORM===================================
'platform': 'PLATFORM_UNSPECIFIED',
"text": {
"text": [
"Esta es una respuesta por escritura de PLATFORM_UNSPECIFIED" + descript;
]
},
}
]
}
sendResponse(responseToUser); // Send simple response to user
});
},
these are links to format your json:

Nice day!
after searching out i find guide which can help on this :
we need to first create chat bot on dialogflow/ api.pi
Then need to train our bot and need to use webhook as fullfillment in
response.
Now we need to setup firebase-tools for sending reply and doing
changes in firebase database.
At last we need to integrate dialogflow with google assistant using google-actions
Here is my sample code i used :
`var admin = require('firebase-admin');
const functions = require('firebase-functions');
admin.initializeApp(functions.config().firebase);
var database = admin.database();
// // Create and Deploy Your First Cloud Functions
// // https://firebase.google.com/docs/functions/write-firebase-functions
//
exports.hello = functions.https.onRequest((request, response) => {
let params = request.body.result.parameters;
database.ref().set(params);
response.send({
speech: "Light controlled successfully"
});
});`
Im stuck!
I'm sending a POST request to a server via AXIOS from a VUE app.
Everything works and the server responds.
The problem is, that the .then method never gets called. How could that be?
Bonus question how are you doing your requests from VUE?
Many thanks
methods:{
customMethod1: function() {
//AXIOS
var config = {
headers: {'My Custom Header 1': 'Header-Value'}
};
//POST request
axios.post('http://192.168.56.101:5000/post1', {name: 'Dave'}, config)
.then(function(response){
alert("posted successfully");
});
},
}
Have you confirmed via a tool like Fiddler that the server actually sends a response? It could be that the server never actually responds.
I just found the solution, and I don't know if I should share it with the person who posted this question : he could at least answer to the others trying to help him.
As I find many answers here I post my solution (maybe not the correct answer but it works)
It's not a vue.js issue, nor axios, the .then statement is called only when you return something on server side.
Some code to explain :
Product.update(
{
productName: req.body.productName,
productDesc: req.body.productDesc,
productOwner: 0,
productImage: req.body.productImage,
productState: req.body.ProductState,
productPrice: req.body.ProductPrice
},
{
where: {
id: req.body.id
}
})
.then(function (item) {
console.log("Product update " + item.id);
res.send({id: item.id});
})
.catch(function (err) {
console.log("Product update error " + err);
});
the important line here is :
res.send({id: item.id});
If you return nothing at server side your .then at client side is not called.
let me know if it works but +1 me ;-)
I've created an html file with embedded Watson Virtual Agent chat bot, code similar below, with WVA strictly using the building core capabilities:
IBMChat.init({
el: 'ibm_chat_root',
baseURL: 'https://api.ibm.com/virtualagent/run/api/v1',
botID: '',
XIBMClientID: '',
XIBMClientSecret: ''
});
What I noticed is if I run the WVA in Preview mode, and have input "pay bill", the WVA can come back with two piece response, with first:
Accessing your account information...
and second the make payment:
Your account balance is $42.01 due on 5/17/2017. What would you like to do? (More options coming soon!)
However, if I enter the same in my HTML chatbot, the response only comes back with the first part:
Accessing your account information...
and second part never comes out.
Does anyone else experience the same problem?
The version in the "Preview" mode has some mock "action" handlers setup. Obviously, not every one of you users would owe $42! In the sample code on the github, the mock action handlers are not setup. There are examples on how to subscribe to those action events with handlers here: https://github.com/watson-virtual-agents/chat-widget/tree/master/examples/basic-actions-example
As of 5/31/17 you can cover all the built in actions using the code snippet below...
const config = { instance: null };
const getUserProfileVariablesMap = {
'bill_amount': '42.01',
'payment_due_date': (() => {
const currentDate = new Date(new Date().getTime() + 24 * 60 * 60 * 1000);
return `${currentDate.getMonth() + 1}/${currentDate.getDate()}/${currentDate.getFullYear()}`;
})(),
'authorized_users': 'Bob Everyman and Jane Doe'
};
const getUserProfileVariables = (data) => {
const variables = data.message.action.args.variables;
variables.forEach(v => {
const value = getUserProfileVariablesMap[v];
(value) ? config.instance.profile.set(v, value) : config.instance.profile.set(v, '[sample data]');
});
config.instance.sendSilently('success');
};
const success = () => config.instance.sendSilently('success');
const agent = () => config.instance.receive('On your own site you would run code to connect to an agent now.');
const accountSettings = () => config.instance.receive('On your own site you would run code to open the Account Settings page now.');
function registerActions(instance) {
config.instance = instance;
instance.subscribe('action:getUserProfileVariables', getUserProfileVariables);
instance.subscribe('action:updateAddress', success);
instance.subscribe('action:updateUserName', success);
instance.subscribe('action:updatePhoneNumber', success);
instance.subscribe('action:updateEmail', success);
instance.subscribe('action:payBill', success);
instance.subscribe('action:sendPaymentReceipt', success);
instance.subscribe('action:agent', agent);
instance.subscribe('action:openAccountSettingsPage', accountSettings);
};
window.IBMChatActions = {
registerActions: registerActions
};
// window.IBMChatActions.registerActions(window.IBMChat);
On the Administrative Preview, you are getting fake code stubs that handle action requests from the agent.
When one of these actions are invoked, the widget will print the "Processing..." message and then invoke all registered subscribers for that action. It is up to these registered subscribers to continue the conversation flow by silently sending "success", "failure", or "cancel" back to the server.
For example, the agent might pass down the "payBill" action. You would want to call your payment gateway, determine if it was successful, and then notify the agent of the result:
IBMChat.init(/* Settings */);
IBMChat.subscribe('action:payBill', function() {
var data = {
amount: IBMChat.profile.get('amount'),
card: {
number: IBMChat.profile.get('cc_number'),
// ... other private card data
}
};
$.post('https://www.myserver.com/payment-gateway', data)
.done( function() {
IBMChat.sendSilently('success');
})
.fail( function() {
IBMChat.sendSilently('failure');
});
});
Actions Documentation
https://github.com/watson-virtual-agents/chat-widget/blob/master/docs/DOCS.md#actions
I am implementing a front-end in ember 1.13 with a Rails back-end and having the following problem:
After the user is authenticated, I don't seem to be able to retrieve the user's record from the back-end. The browser debugger does not even show a request being made. This is code:
// app/services/session-user.js
import Ember from 'ember';
const { inject: { service }, RSVP } = Ember;
export default Ember.Service.extend({
session: service('session'),
store: service(),
loadCurrentUser() {
currentUser: {
var userId = this.get('user_id');
if (!Ember.isEmpty(userId)) {
return this.get('store').findAll('user', userId);
}
}
}
});
There is a login controller which handles the authentication. But the code for getting the data is in the applications's route:
// app/routes/application.js
import Ember from 'ember';
import ApplicationRouteMixin from 'ember-simple-auth/mixins/application-route-mixin';
const { service } = Ember.inject;
export default Ember.Route.extend(ApplicationRouteMixin, {
sessionUser: service('session-user'),
beforeModel() {
if (this.session.isAuthenticated) {
return this._loadCurrentUser();
}
},
sessionAuthenticated() {
this._loadCurrentUser();
},
_loadCurrentUser() {
return this.get('sessionUser').loadCurrentUser();
},
});
For extra measure I am defining the session store:
// app/session-stores/application.js
import Adaptive from 'ember-simple-auth/session-stores/adaptive';
export default Adaptive.extend();
If there are files I should post, please let me know.
Any hints will be highly appreciated as I am rather new to ember. I have spent several hours researching without luck, as things seem to have changed quite a lot throughout versions.
Look at your service code.
var userId = this.get('user_id');
if (!Ember.isEmpty(userId)) {
return this.get('store').findAll('user', userId);
}
I don't see code that you provided in question where you setting up user_id variable. So if user_id not defined then if statement won't get executed because of !.
I'm working in an implementation using SignalR and the Kendo Scheduler. When a new task is created (for exemple), the SchedulerDataSource transport send the connection hub id to the server as an additional parameter:
transport: {
read: { url: global.web_path + 'Home/Tasks' },
update: { url: global.web_path + 'Home/UpdateTask', type: 'PUT', contentType: 'application/json' },
create: { url: global.web_path + 'Home/CreateTask', type: 'POST', contentType: 'application/json' },
destroy: { url: global.web_path + 'Home/DeleteTask', type: 'DELETE', contentType: 'application/json' },
parameterMap: function (options, operation) {
if (operation == "destroy" && options.models) {
return JSON.stringify({ taskId: options.models[0].Id, callerId: $.connection.hub.id });
}
if (operation !== "read" && options.models) {
return JSON.stringify({ tasks: options.models, callerId: $.connection.hub.id });
}
}
},
The server do whatever it has to do, and send a notification to every other user, except de caller:
[HttpPost]
public JsonResult CreateTask(List<ScheduledEvent> tasks, string callerId)
{
...create task and other stuff
//broadcast the newly created object to everyone except caller
var hubContext = GlobalHost.ConnectionManager.GetHubContext<Notebooks.Hubs.SchedulerHub>();
hubContext.Clients.AllExcept(callerId).UpdateSchedule(task);
//return the object to caller
return Json(task);
}
Once the other clients receive a new task from the hub, it is added to the SchedulerDataSource:
hub.client.updateSchedule = function (scheduledEvent) {
schedulerDataSource.add(scheduledEvent);
}
Everything seems to work fine, and it really took me some time to realize this behavior: if a client have the scheduler window open, this window is closed once the schedulerDataSource is updated. This is expected or am I doing something wrong?
Edit: I just realized how old this question is, so you have probably moved on to other things by now, or the pushCreate method may not have existed back then.
I think this may be how it works, but it seems like it should be able to add those events behind the scenes without having to close the edit window. Have you tried the pushCreate method? If that doesn't work, since the add automatically closes the edit dialog, maybe when the events come in, if the dialog is open, you could store the new events, then add them when the user closes the edit dialog.
My answer is now even older ;) but I faced this very same issue today.
First, I'm quite sure this is indeed the expected behavior. You can see in the kendo sources the call of the close editor window method in the transport update and create methods of the scheduler.
Below is what I've done to bypass the issue .
The idea is as simple as to prevent the edit window to close when an appointment modification comes from another hub client.
Server-side : modify the hub methods (example with update method)
public MyAppointmentViewModel Update(MyAppointmentViewModel appointment)
{
if (!appointmentService.Update(appointment))
throw new InvalidOperationException("Something went wrong");
else
{
Clients.Others.PrepareBeforeAddOrUpdateSignal(appointment.Id);
Clients.Others.Update(appointment);
return appointment;
}
}
Here you see we inform every other clients (through PrepareBeforeAddOrUpdate) we're about to update an appintment.
Client-side now (in index.cshtml for instance)
schedulerHub.client.prepareBeforeAddOrUpdateSignal = function(id){ lastModifiedRdvId = id; };
schedulerHub.client.create = function(appointment){ lastModifiedRdvId = 0; }; /* reset the variable for next time */
schedulerHub.client.update = function(appointment){ lastModifiedRdvId = 0; }; /* reset the variable for next time */
function SchedulerEditor()
{
return $(".k-scheduler-edit-form").data("kendoWindow");
}
var eventBeforeChanges = null;
var lastModifiedRdvId = 0;
function onEditorClose(e) {
if (eventBeforeChanges != null) {
if (lastModifiedRdvId > 0 && eventBeforeChanges.Id != lastModifiedRdvId)
e.preventDefault();
else {
var editWin = SchedulerEditor(); /* unbind this callback and use default behavior again */
editWin.unbind('close', onEditorClose);
}
}}
function onEditRdv(e) {
var editWin = SchedulerEditor();
if (editWin != null) /*Bind the close event */
editWin.unbind('close', onEditorClose).bind('close', onEditorClose);
eventBeforeChanges = e.event;
/* continue onEditRdv */
}
you see here the close event is prevented when the appointment id is not the appointment id beeing updated by the current client.
And fortunately, preventing the close event prevents the annoying behavior of having a sort of ghost appointment after one has been changed by another hub client.
I'm sorry if I'm not clear or if the code isn't clear enough. I can provide more information if necessary.
Bye
