I started working on small project using Laravel and Nuxt Js, so i have created a small for to add users in the database. every thing is going well, i have a small issue, my axios script send multiple request like a loop :
this is the full code :
<script>
import $ from 'jquery'
import Swal from 'sweetalert2'
import toastr from 'toastr'
import Vue from 'vue'
Vue.component('pagination', require('laravel-vue-pagination'))
export default {
layout: 'app',
data () {
return {
laravelData: {},
formFields: {},
search: null,
refresh: false
}
},
watch: {
refresh () {
this.store()
this.refresh = false
}
},
mounted () {
$('a.just-kidding').hide()
this.index(1)
},
methods: {
index (page = 1) {
this.$axios.$get('/customer?page=' + page).then((response) => {
this.laravelData = response
this.refresh = true
})
},
store () {
const formData = $('#add-customer').serialize()
return this.$axios.$post('/customer/store', formData).then((response) => {
this.refresh = true
})
},
find () {
if (this.search === '') {
this.index()
} else {
this.$axios.$get('/customer/find?customer=' + this.search).then((response) => {
this.laravelData = response
})
}
},
destroy (customerId) {
Swal.fire({
title: 'Are you sure?',
text: "You won't be able to revert this!",
type: 'warning',
showCancelButton: true,
confirmButtonColor: '#3085d6',
cancelButtonColor: '#d33',
confirmButtonText: 'Yes, delete it!'
}).then((result) => {
if (result.value) {
// this.$Progress.start();
this.$axios.$get('/customer/destroy?customer=' + customerId).then((response) => {
if (response.success) {
toastr.success(response.error, 'Ahoy Hoy !!', { 'positionClass': 'toast-top-left' })
this.refresh = true
} else {
toastr.error(response.error, 'Owh :( !!', { 'positionClass': 'toast-top-left' })
}
})
// this.$Progress.finish();
}
})
}
}
}
</script>
and here is my controller :
public function store(Request $request)
{
DB::transaction(function () use ($request){
$customerQuery = Customer::create($request->post('general'))->id;
$shippingInfos = array_merge(array('customer_id' => $customerQuery), $request->post('address'));
$shippingQuery = Shipping::create($shippingInfos);
return true;
});
}
i have created a Middleware page called cors in my laravel,
<?php
namespace App\Http\Middleware;
use Closure;
class Cors
{
/**
* Handle an incoming request.
*
* #param \Illuminate\Http\Request $request
* #param \Closure $next
* #return mixed
*/
public function handle($request, Closure $next)
{
return $next($request)
->header('Access-Control-Allow-Origin', '*')
->header('Access-Control-Allow-Methods', 'GET, POST, PUT, PATCH, DELETE, OPTIONS')
->header('Access-Control-Allow-Headers', 'Content-Type, Authorization');
}
}
watch: {
refresh () {
this.store()
this.refresh = false
}
},
This will cause an infinite loop, because you're changing this.refresh in the watcher function that's monitoring this.refresh, which will re-trigger the watch function, which will change it, which will trigger the watcher, which will change it, which will trigger the watcher, which will change it, which will trigger the watcher, which will change it, which will trigger the watcher, which will change it...
You get the point.

I want to save this result as amount, when I do console.log(result); I see that know what number I put in input, but how to save it in Laravel function?
function makeOffer(nftid) {
swal({
title: "Do you want to make offer?",
text: "Enter amount",
input: 'text',
type: 'warning',
showCancelButton: true,
showConfirmButton: true,
confirmButtonColor: '#3085d6',
cancelButtonColor: '#d33',
}).then((result) => {
if (result) {
axios.post("/myaccount/makeoffer/" + nftid).then(response => {
window.location.reload();
});
}
});
}
public function makeOffer($id, Request $request){
$nft=NFT::where('id','=',$id)->first();
if($nft->status=='pending') {
$nft_auction = new NftAuctions();
$nft_auction->nft_id = $nft->id;
$nft_auction->owner_id = $nft->user->id;
$nft_auction->buyer_id = Auth::id();
$nft_auction->amount = "there should be amount";
$nft_auction->status = 'pending';
$nft_auction->save();
return back();
}
else{
abort(404);
}
}
Axios' .post() method takes 2 arguments; the URL and the data you want to send to the backend, so adjust it to:
axios.post("/myaccount/makeoffer/" + nftid, {'amount': result})
.then(response => {
window.location.reload();
});
Then, in your backend, you can access this as $request->input('amount'):
public function makeOffer($id, Request $request){
$nft = NFT::find($id);
if($nft->status == 'pending') {
$nftAuction = new NftAuctions();
// ...
$nftAuction->amount = $request->input('amount');
// ...
$nftAuction->save();
return back();
}
}
Some notes:
Model::where('id', '=', $id)->first() can be shortened to Model::find($id).
Model names are PascalCase and singular: NFT should be Nft, and NftAuctions should be NftAuction

I am using a vtiger Crm system and I would like to use the pop up notification to display my own messages. I wrote an event handler that triggers after model save, in this handler I would like to call the notification box with my own message.
Here is a working example that is from the 'Products' module handlers, this code was pre-written, it checks if there were duplicate item numbers and shows a message 'LBL_DUPLICATE_item_number' in the pop-up box
class Products_DuplicateItemNumber_Handler
{
/**
* EditViewPreSave handler function.
*
* #param App\EventHandler $eventHandler
*/
public function editViewPreSave(App\EventHandler $eventHandler)
{
$recordModel = $eventHandler->getRecordModel();
$response = ['result' => true];
$fieldModel = $recordModel->getModule()->getFieldByName('item_number');
if ($fieldModel->isViewable() && ($item_number = $recordModel->get('item_number'))) {
$queryGenerator = new \App\QueryGenerator($recordModel->getModuleName());
$queryGenerator->setStateCondition('All');
$queryGenerator->setFields(['id'])->permissions = false;
$queryGenerator->addCondition($fieldModel->getName(), $item_number, 'e');
if ($recordModel->getId()) {
$queryGenerator->addCondition('id', $recordModel->getId(), 'n');
}
if ($queryGenerator->createQuery()->exists()) {
$response = [
'result' => false,
'hoverField' => 'item_number',
'message' => App\Language::translate('LBL_DUPLICATE_item_number', $recordModel->getModuleName())
];
}
}
return $response;
}
}
However, when i try to return $respone in 'editViewPreSave' of another module, nothing happens.
After some digging around i found out that the system uses 'Pnotify' library to show the pop up message, and i belive it's being called in a js file called 'edit.js' in this path 'public_html/layouts/basic/modules/Vtiger/resources'
preSaveValidation: function (form) {
const aDeferred = $.Deferred();
if (form.find('#preSaveValidation').val()) {
document.progressLoader = $.progressIndicator({
message: app.vtranslate('JS_SAVE_LOADER_INFO'),
position: 'html',
blockInfo: {
enabled: true
}
});
let formData = new FormData(form[0]);
formData.append('mode', 'preSaveValidation');
AppConnector.request({
async: false,
url: 'index.php',
type: 'POST',
data: formData,
processData: false,
contentType: false
})
.done((data) => {
document.progressLoader.progressIndicator({ mode: 'hide' });
let response = data.result;
for (let i = 0; i < response.length; i++) {
if (response[i].result !== true) {
app.showNotify({
text: response[i].message ? response[i].message : app.vtranslate('JS_ERROR'),
type: 'error'
});
if (response[i].hoverField != undefined) {
form.find('[name="' + response[i].hoverField + '"]').focus();
}
}
}
aDeferred.resolve(data.result.length <= 0);
})
.fail((textStatus, errorThrown) => {
document.progressLoader.progressIndicator({ mode: 'hide' });
app.showNotify({
text: app.vtranslate('JS_ERROR'),
type: 'error'
});
app.errorLog(textStatus, errorThrown);
aDeferred.resolve(false);
});
} else {
aDeferred.resolve(true);
}
return aDeferred.promise();
},
I believe that 'app.showNotify' is the function called to display the pop-up box, yet i'm not sure how to replicate the code for my own use, i would like to know the best approach to do this
I'm studying javascript and mithril.js 1.1.6. I'm writing down a simple web app in which users land on a page where he can login. Users who already did login land on a different page. I'm trying this using conditional routing, here is the main component:
const m = require("mithril");
...
import Eventbus from './whafodi/eventbus.js';
import WelcomePage from './ui/welcome.js';
import User from './model/user.js';
var eventbus = new Eventbus();
function MyApp() {
return {
usrAuth: function() {
m.route(document.body, "/", {
"/": { view: () => m("p", "hello")}
})
},
usrNotAuth: function() {
m.route(document.body, "/", {
"/": { render: v => m(WelcomePage, eventbus) }
})
},
oninit: function(vnode) {
vnode.state.user = new User();
eventbus.subscribe({
type: "login",
handle: function(action) {
vnode.state.user.token = action.token;
console.log(JSON.stringify(vnode.state.user));
}
});
},
view: function(vnode) {
if(vnode.state.user.token) {
this.usrAuth();
} else {
this.usrNotAuth();
}
}
}
};
m.mount(document.body, MyApp);
MyApp is the main component. It check if user has a token, then return the proper route. This is the component that is in charge to let users login:
const m = require("mithril");
const hellojs = require("hellojs");
function TopBar(node) {
var bus = node.attrs.eventbus;
function _login() {
hellojs('facebook').login({scope:'email'});
}
return {
oninit: function(vnode) {
hellojs.init({
facebook: XXXXXXX,
}, {
redirect_uri: 'http://localhost'
});
hellojs.on('auth.login', auth => {
var fbtoken = auth.authResponse.access_token;
m.request({
method:"POST",
url:"./myapp/login/fb/token",
data:auth.authResponse,
background: true
}).then(function(result){
console.log(result);
bus.publish({ type: "login", token: result.jwttoken });
m.route.set("/");
}, function(error){
console.log(error);
bus.publish({ type: "login", token: "" });
});
});
},
view: function(vnode) {
return m("div", [
m("button", { onclick: _login }, "Login")
]);
}
}
}
export default TopBar;
TopBar component occurs in the WelcomePage component mentioned in the main one. TopBar renders a button and use hello.js to login. It uses the EventBus bus parameter to tell main component user logged in (there is an handler in main component to update the user model). Once user logins, event is fired and main component updates the user model. Good. Now, how can trigger the main component to load the right route?
I read mithril'docs again and I found that RouteResolvers perfectly suit my needs. Here is an example:
var App = (function() {
var login;
function isLoggedIn(component) {
if(login) {
return component;
} else {
m.route.set("/hey");
}
}
return {
oninit: function(vnode) {
EventBus.subscribe({
type: "login",
handle: function(action) {
console.log("incoming action: " + JSON.stringify(action));
login = action.value;
}
});
},
oncreate: function(vnode) {
Foo.eventbus = EventBus;
Bar.eventbus = EventBus;
Hey.eventbus = EventBus;
m.route(document.body, "/hey", {
"/foo": {
onmatch: function(args, requestedPath, route) { return isLoggedIn(Foo); }
},
"/bar": {
onmatch: function(args, requestedPath, route) { return isLoggedIn(Bar); }
},
"/hey": Hey
});
},
view: function(vnode) {
return m("div", "home..");
}
};
})();
Eventbus is used to let components communicate with App. They fire events (login type events) that App can handle. I found convenient to pass Eventbus the way oncreate method shows, I can use Eventbus in each component's oncreate to let components fire events.
I have a vue component for video upload, where I am warning a user when he tries to navigate away during the video upload that he will lose the file if he does so, like this:
ready() {
window.onbeforeunload = () => {
if (this.uploading && !this.uploadingComplete && !this.failed) {
this.confirm('Are you sure you want to navigate away? Your video won't be uploaded if you do so!');
}
}
}
I am using sweetalert to alert the user about it. But how can I then make it stay on the same page, and prevent the navigation away before he confirms that he wants to navigate away?
This is the whole component:
<script>
function initialState (){
return {
uid: null,
uploading: false,
uploadingComplete: false,
failed: false,
title: null,
link: null,
description: null,
visibility: 'private',
saveStatus: null,
fileProgress: 0
}
}
export default {
data: function (){
return initialState();
},
methods: {
fileInputChange() {
this.uploading = true;
this.failed = false;
this.file = document.getElementById('video').files[0];
this.store().then(() => {
var form = new FormData();
form.append('video', this.file);
form.append('uid', this.uid);
this.$http.post('/upload', form, {
progress: (e) => {
if (e.lengthComputable) {
this.updateProgress(e)
}
}
}).then(() => {
this.uploadingComplete = true
}, () => {
this.failed = true
});
}, () => {
this.failed = true
})
},
store() {
return this.$http.post('/videos', {
title: this.title,
description: this.description,
visibility: this.visibility,
extension: this.file.name.split('.').pop()
}).then((response) => {
this.uid = response.json().data.uid;
});
},
update() {
this.saveStatus = 'Saving changes.';
return this.$http.put('/videos/' + this.uid, {
link: this.link,
title: this.title,
description: this.description,
visibility: this.visibility
}).then((response) => {
this.saveStatus = 'Changes saved.';
setTimeout(() => {
this.saveStatus = null
}, 3000)
}, () => {
this.saveStatus = 'Failed to save changes.';
});
},
updateProgress(e) {
e.percent = (e.loaded / e.total) * 100;
this.fileProgress = e.percent;
},
confirm(message) {
swal({
title: message,
text: null,
type: "warning",
showCancelButton: true,
cancelButtonText: "Cancel",
cancelButtonColor: '#FFF',
confirmButtonColor: "#2E112D",
confirmButtonText: "Yes, delete"
}).then(function(){
this.$data = initialState();
}.bind(this), function(dismiss) {
// dismiss can be 'overlay', 'cancel', 'close', 'esc', 'timer'
if (dismiss === 'cancel') { // you might also handle 'close' or 'timer' if you used those
// ignore
} else {
throw dismiss;
}
})
}
},
ready() {
window.onbeforeunload = () => {
if (this.uploading && !this.uploadingComplete && !this.failed) {
this.confirm('Are you sure you want to navigate away? Your video won't be uploaded if you do so!');
}
}
}
}
</script>
Mozilla documentation suggests
window.onbeforeunload = function(e) {
var dialogText = 'Dialog text here';
e.returnValue = dialogText;
return dialogText;
};
and also states that:
Since 25 May 2011, the HTML5 specification states that calls to window.alert(), window.confirm(), and window.prompt() methods may be ignored during this event. See the HTML5 specification for more details.
Source contains many other details regarding reasons and what to expect from modern browsers.
This question seems to be a duplicate of yours.
This answer suggests that to avoid weird browser behaviour you should set handler only when it's to prevent something (that is while navigating away should trigger a confirmation dialog)
But how can I then make it stay on the same page, and prevent the navigation away before he confirms that he wants to navigate away?
Add return false; to stop the event.
if (this.uploading && !this.uploadingComplete && !this.failed) {
this.confirm("Are you sure you want to navigate away? Your video won't be uploaded if you do so!");
return false; // <==== add this
}
return false; does 3 separate things when you call it :
event.preventDefault(); – It stops the browsers default behaviour.
event.stopPropagation(); – It prevents the event from propagating (or “bubbling up”) the DOM.
Stops callback execution and returns immediately when called.
I'm creating a custom directive to make a form submit via ajax - however I can't seem to get validation errors to bind to the Vue instance.
I am adding my directive here:
<form action="{{ route('user.settings.update.security', [$user->uuid]) }}" method="POST"
enctype="multipart/form-data" v-ajax errors="formErrors.security" data="formData.security">
My directive looks like:
Vue.directive('ajax', {
twoWay: true,
params: ['errors', 'data'],
bind: function () {
this.el.addEventListener('submit', this.onSubmit.bind(this));
},
update: function (value) {
},
onSubmit: function (e) {
e.preventDefault();
this.vm
.$http[this.getRequestType()](this.el.action, vm[this.params.data])
.then(this.onComplete.bind(this))
.catch(this.onError.bind(this));
},
onComplete: function () {
swal({
title: 'Success!',
text: this.params.success,
type: 'success',
confirmButtonText: 'Back'
});
},
onError: function (response) {
swal({
title: 'Error!',
text: response.data.message,
type: 'error',
confirmButtonText: 'Back'
});
this.set(this.vm, this.params.errors, response.data);
},
getRequestType: function () {
var method = this.el.querySelector('input[name="_method"]');
return (method ? method.value : this.el.method).toLowerCase();
},
});
And my VUE instance looks like:
var vm = new Vue({
el: '#settings',
data: function () {
return {
active: 'profile',
updatedSettings: getSharedData('updated'),
formData: {
security: {
current_password: ''
}
},
formErrors: {
security: []
},
}
},
methods: {
setActive: function (name) {
this.active = name;
},
isActive: function (name) {
if (this.active == name) {
return true;
} else {
return false;
}
},
hasError: function (item, array, sub) {
if (this[array][sub][item]) {
return true;
} else {
return false;
}
},
isInArray: function (value, array) {
return array.indexOf(value) > -1;
},
showNotification: function () {
if (this.updatedSettings) {
$.iGrowl({
title: 'Updated',
message: 'Your settings have been updated successfully.',
type: 'success',
});
}
},
}
});
However, when I output the data, the value for formErrors.security is empty
Any idea why?
The issue is with the this.set(/* ... */) line. this.set doesn't work the same as Vue.set or vm.$set.
this.set attempts to set the path that you passed to the directive: v-my-directive="a.b.c". So running this.set('foo') will attempt to set $vm.a.b.c to 'foo'.
What you want to do is this:
(ES6)
this.params.errors.splice(0, this.params.errors.length, ...response.data)
(Vanilla JS)
this.params.errors.splice.apply(this.params.errors, [0,this.params.errors.length].concat(response.data))
That will update whatever Object is tied to the errors param on the DOM Node. Make sure that you do v-bind:errors="formErrors.security" or :errors="formErrors.security".
