Error when sending dropzone images to laravel backend

So I have a dropzone file uploader. each successfull upload returns the following
File: {
"upload": {
"uuid": "f89f409b-7e49-4503-98d8-dc060e75b874",
"progress": 0,
"total": 5017004,
"bytesSent": 0,
"filename": "20190902_115950.jpg"
},
"status": "error",
"previewElement": {},
"previewTemplate": {},
"accepted": false,
"dataURL": "data:image/jpeg;base64,/9j/4XGiRXh/WU8GGXVL5BHN5PW...",
"width": 3024,
"height": 4032
}
I have a laravel backend with a request validation for this:
rules = [
...
'featured_image' => 'image',
]
However, my laravel backend returns that the featured image field must be an image. So I'm not sure what format the backend expects.
My dropzone component looks like this:
<template>

I have tried to use file system (fs module) but, not getting that how to use that FS module.
could anyone explain with proper example.

and render student list and perform remove record
Now next i want to Pass updated list using emit & update the JSON as well
This code is working properly just i want to update local json file after delete record.

Hey After some searches I found a solution so sharing here it may help who stuck related to this issue,
As i show above code i just wanted to add code where i can write my json file. so i have made some changes in code, that is as below.
Add command in CMD :
json-server --watch './src/data/studentData.json' --port 3001
then it will provide local link from where you can open you json data
Resources
http://localhost:3001/studente
see below image :
StudentRegistration.vue
this code should be in script tag in StudentRegistration.vue component
In this file added below code added code in method and created create method
export default {
name: 'StudentRegi',
components:{
studentCard
},
data() {
return {
studentsGetData: []
// studentsGetData: studentData,
}
},
methods: {
studentRemoveId(studid){
fetch(`http://localhost:3001/studente/${studid.id}`,
{
method: 'DELETE',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
}
}).then(resp => {
console.log('res ::=> ', resp.data);
resp.data;
}).catch(error => {
console.log(error);
});
this.studentsGetData = this.studentsGetData.filter( item => {
return item.id !== studid.id
});
}
},
async created(){
await fetch('http://localhost:3001/studente')
.then(res => res.json())
.then(data => {
console.log('data ::=> ', data);
this.studentsGetData = data
} )
.catch(err => console.log(err.message))
}
}
Now Run your project

I can't show the meteorological icon

I am creating a time application using the Openweather API. I try to show the meteorological icon corresponding to the selected city and the meteorological state.
My code is as follows:
HTML:
<div class="column">
<div class="media-content">
<div class="content">
<p>
<strong>
<h1 class="has-text-inf o"> {{ ciutatActual.weather[0].icon }} </h1>
</strong>
</p>
</div>
</div>
</div>
javascript:
var vm = new Vue({
el: '#eltemps',
data: {
selectedCity: "",
ciutatActual: null,
ciutats: [
"Barcelona",
"Lleida",
"Zaragoza",
"Sevilla",
"Madrid",
"Paris",
"Melbourne",
"Moscow",
"Pekin",
"Marrakech"]
},
created: function () {
this.selectedCity = this.ciutats[0]
},
watch: {
selectedCity: function (){
this.getWeather(this.selectedCity)
}
},
methods: {
getWeather(city) {
const url = 'https://api.openweathermap.org/data/2.5/weather?q=' + city + '&units=metric&lang=ca&appid=8660dddfbe5f16ee37dbd6883d8f07d5';
fetch(url)
.then(function (response) {
return response.json()
})
.then(function (item) {
vm.ciutatActual = item;
})
.catch(function(error) {
console.log(error);
})
},
itemClicked: function(item) {
this.getWeather();
this.onClick(item);
}
}
})
The ruling comes from here: {{ciutatactual.weather [0] .icon}}
that instead of showing the icon it shows me just one code

Vue method not passing data to array of objects

So I'm going to be explaining this in the best way possible as I don't understand what might be causing this issue on my end as I feel like I've followed all of the directions and keep hitting a brick wall.
Here is my vue.js app:
new Vue({
name: 'o365-edit-modal-wrapper',
el: '#o365-modal-edit-wrapper',
data: function() {
const default_apps = [
{
'post_title': 'Excel',
}, {
'post_title': 'Word',
}, {
'post_title': 'SharePoint',
}];
console.log(default_apps);
const default_apps1 = this.get_array_of_post_objects('application_launcher');
console.log(default_apps1);
return {
available_list: [],
selected_list: default_apps.map(function(name, index) {
return {
name: name.post_title,
order: index + 1,
fixed: false
};
}),
}
},
methods: {
get_array_of_post_objects(slug) {
let items = [];
wp.api.loadPromise.done(function () {
const Posts = wp.api.models.Post.extend({
url: wpApiSettings.root + 'menus/v1/locations/' + slug,
});
const all_posts = new Posts();
all_posts.fetch().then((posts) => {
items.push(...posts.items);
});
});
return items;
},
},
computed: {
dragOptions() {
// Pass in additional <draggable> options inside the return for both lists.
return {
tag: 'div',
group: 'o365apps',
disabled: !this.editable,
ghostClass: "ghost",
};
},
},
});
Inside my methods, I have a method called get_array_of_post_objects which returns an array of objects that I'm pulling through.
So inside data, I'm console logging my manual default_apps and my default_apps1 which is the method. Both of the arrays of objects have post_title: "something" inside.
Here is the return that I'm getting:
Inside my mapping, when I define default_apps, my IDE returns some result for name but when I switch it over to default_apps1, it's not finding any results as shown below:
I don't know what else to look at - All help would be appreciated!
Here is the HTML code if that is needed:
<div class="column is-half-desktop is-full-mobile buttons">
<nav class="level is-mobile mb-0">
<div class="level-left">
<div class="level-item is-size-5 has-text-left">Selected</div>
</div>
<div class="level-right">
<div class="level-item" #click="orderList()"><i class="fas fa-sort-alpha-up is-clickable"></i></div>
</div>
</nav>
<hr class="mt-1 mb-3">
<!-- Decorator: # also known as v-on: -->
<!-- Bind: : also known as v-bind: -->
<draggable class="list-group"
v-model="selected_list"
v-bind="dragOptions"
:move="onMove"
#add="onAdd"
#remove="onRemove"
#start="isDragging=true"
#end="isDragging=false">
<button class="button is-fullwidth is-flex list-group-item o365_app_handle level is-mobile" v-for="(app, index) in selected_list" :key="app.order">
<div class="level-left">
<span class="icon" aria-hidden="true">
<img :src="`<?= Path::o365('${app.name}' . '.svg'); ?>'`" />
</span>
<span>{{app.name}}</span>
</div>
<div class="level-right is-hidden-desktop">
<span class="icon has-text-danger is-clickable" #click="remove(index)">
<i class="fas fa-times"></i>
</span>
</div>
</button>
</draggable>
</div>

I'm not 100% sure what your app is supposed to do, so modify it for your needs.
Here the selected_list will be empty first.
Then we call your method, which is asynchronous, and once it's done selected_list gets populated.
new Vue({
name: 'o365-edit-modal-wrapper',
el: '#o365-modal-edit-wrapper',
data: function() {
return {
available_list: [],
selected_list: [],
}
},
created() {
this.get_array_of_post_objects("add-your-slug")
},
methods: {
get_array_of_post_objects(slug) {
wp.api.loadPromise.done(function() {
const Posts = wp.api.models.Post.extend({
url: wpApiSettings.root + 'menus/v1/locations/' + slug,
});
const all_posts = new Posts();
all_posts.fetch().then((posts) => {
// You might want to modify posts for your needs
this.selectedList = posts
});
});
},
},
});

Passing axios data to view template

I am creating a simple SPA using vue.js and axioz as a scripts (not cli, etc)
So far I am able to pull data from a json then render and paginate the list,and when an item is clicked I am able to console log the data for the specific entry.

My problem is i cannot console log the title or any internal fields of the data object, as I want to be able to add the title etc into the view area.
Any help or pointers would be much appreciated.

The response is in array form and you cannot access array object element without looping array.
If you wish to get title of first post, then you can do as shown below,
this.title = response.data[0].title
To access all posts title, you can use v-for loop in you vue template. Here is little example on how you can accomplish that,
<div v-for="post in posts">
<span>{{ post.title }}</span>
</div>
