Is there a way of displaying my data on Vue Component?

I'm working on a project which i need to fetch "clients" data on a table.
The data actually comes, but i can't manage to display it. Here's my template part, where i call for info with a v-for.
<tbody>
<tr v-for="item in clients" v-bind:key="item.id">
<td>{{ item.id }}</td>
<td>{{ item.name }}</td>
<td>{{ item.email }}</td>
<td>{{ item.documents.cpf || item.documents.cnpj }}</td>
<td>{{ item.documents.celular }}</td>
<td>{{ item.status }}</td>
<td v-if="item.address">
{{ `${item.address.localidade} / ${item.address.uf}` }}
</td>
<td v-else>-</td>
<td>
<a :href="`/ver-cliente/${item.id}`"
></a>
</td>
</tr>
</tbody>
On my DevTools, the data is shown:
Full DevTools with all errors (some of them are from other pages)
My script part:
export default {
data: () => ({
clients: [],
paginationData: {
lastPage: 0,
currentPage: 1,
},
loading: false,
}),
methods: {
getClients(page = 1) {
this.loading = true;
this.$api
.get("/api_v1/clientes", {
params: { page },
})
.then(({ data }) => {
console.log(data);
if (data.success) {
const {
data: result,
per_page,
total,
last_page,
current_page,
} = data.data;
this.clients = result;
this.paginationData = {
perPage: per_page,
total,
lastPage: last_page,
currentPage: current_page,
};
}
})
.finally(() => (this.loading = false));
},
},
mounted() {
this.getClients();
},
};
That' what i managed to do, but it isn't working.
Can anyone give me a hint of what am I doing wrong? Sorry for any rookie mistakes.

It can't find the property cnjp in the item.documents object, so it throws an error. To get rid of that error you can do
item.documents?.cnpj so if the property is not in the object, if will be null instead of throwing an error.

Is there a way of displaying the value of an object inside an array?

I'm building a component on my project, which is actually getting all the data and console logging it, but here's the problem: Inside my array of clients, i have some objects (address, documents, ...), and i can't manage to call them on my table.
My script:
<script>
export default {
data: () => ({
clients: [],
}),
methods: {
getClients() {
this.$api
.get("/api_v1/clientes", {
})
.then((response) => {
this.clients = response.data[0];
console.log(response.data);
})
.catch((e) => {
console.log(e);
});
},
},
mounted() {
this.getClients();
},
};
</script>
My table (inside ):
<tbody>
<tr v-for="client in clients" v-bind:key="client.id">
<td>{{ client.id }}</td>
<td>{{ client.name }}</td>
<td>{{ client.email }}</td>
<td>{{ client.documents.cpf || client.documents.cnpj }}</td>
<td>{{ client.documents.celular }}</td>
<td>{{ client.status }}</td>
<td v-if="client.address">
{{ `${client.address.localidade} / ${client.address.uf}` }}
</td>
<td v-else>-</td>
<td>
<a :href="`/see-client/${client.id}`"
><i class="icon-magnifier"></i
></a>
<i class="icon-check" style="color: green"></i>
<i class="icon-close" style="color: red"></i>
</td>
</tr>
</tbody>
My controller:
public function index(Request $request)
{
$data = [
'pag' => 'All clients',
'link' => '/'
];
return view('clients.index', $data);
}
The data:
Someone have a clue of a different approach i could have? I'm using Vue2. It's one of my first big projects, so previously sorry for any rookie mistake. Thanks for your time and help!

This line is only getting the first client:
this.clients = response.data[0];
response.data is your array of clients (from the looks of things). When you use .data[0], you're getting the first element of the array (i.e. the first client).
Then, this line is trying to loop over 1 client, not an array of clients.
<tr v-for="client in clients" v-bind:key="client.id">
Try changing
this.clients = response.data[0];
to
this.clients = response.data;
If that doesn't work (it looks like you've got a weird data structure), try this instead:
this.clients = response.data.data;
Or this (it's unclear to me how many nested data properties you have):
this.clients = response.data.data.data;

I just made a quick analysis about your code. I think you should polish it a little bit.
Let me start with a quick catch up:
Update yuor js section with:
<script>
export default {
// Please do use the function format instead of lambda expression, it's recommended in the vue2 docs.
data() {
return {
clients: [],
};
},
methods: {
// Change this to an async method, so you can have more control on your code.
async getClients() {
try {
/**
* Here, you should have to know, that your file `routes/api.php` hass all of the prefixed /api routes
* So you have a direct access to /api prefixed routes
* Additionally read a little bit about destructuring.
*/
const response = await this.$api.get("/api/clientes");
// Now, please notice that you have 2 data path names.
this.clients = response.data.data; // {or please follow the correct path to the array container of the clients}.
} catch (e) {
console.log("Check this error: ", e);
}
},
},
// Now, change your mounted to an async method
async mounted() {
// Trust me this is going to work perfectly.
await this.getClients();
},
};
</script>
Now, please, please change your api controller logic to a response()->json(...)
public function index(Request $request)
{
// Your retrieve logic...
return response()->json($data);
}
Finally if you have successfully configured everything abouve, your vue component should be able to retrieve the information correctly, and your tbody must work this way...
<tbody>
<tr v-for="client in clients" v-bind:key="client.id">
<td>{{ client.id }}</td>
<td>{{ client.name }}</td>
<td>{{ client.email }}</td>
<td>{{ client.documents.cpf || client.documents.cnpj }}</td>
<td>{{ client.documents.celular }}</td>
<td>{{ client.status }}</td>
<td v-if="client.address">
<!-- You can replace what you have with: -->
{{ client.address.localidade }} / {{ client.address.uf }}
</td>
<td v-else>
-
</td>
<td>
<a :href="`/see-client/${client.id}`">
<i class="icon-magnifier"></i>
</a>
<i class="icon-check" style="color: green"></i>
<i class="icon-close" style="color: red"></i>
</td>
</tr>
</tbody>

(Vue.js) "Uncaught (in promise) TypeError: Cannot read property 'results' of undefined"

I am trying to display data stored in a Firebase remote database in a Vue 3 webpage with a table however when I route to the display page I return the error. This is what my code looks like.
This is the HTML that displays the table:
<template>
<section v-if="!this.results.length">
No data to show
</section>
<section v-else>
<table class="table">
<thead>
<tr>
<th scope="col">View</th>
<th scope="col">Identification</th>
<th scope="col">Name</th>
<th scope="col">Surname</th>
<th scope="col">Email</th>
</tr>
</thead>
<tbody>
<tr v-for="res in results" :key="res.id">
<!-- <td><button class="btn btn-primary">View</button></td> -->
<td>{{res.idCard}}</td>
<td>{{res.name}}</td>
<td>{{res.surname}}</td>
<td>{{res.email}}</td>
<!-- <td><button class='btn btn-primary'>Update</button></td> -->
</tr>
</tbody>
</table>
</section>
</template>
And this is the Javascript. Here it is supposed to fetch the data from the firebase and push it into the results[] array.
<script>
export default {
data(){
return{
results: []
};
},
methods:{
async getData(){
console.log("Getting data");
try{
const response = await fetch("https://fir-example-56e32-default-rtdb.europe-west1.firebasedatabase.app/contact.json",{
method: 'GET'
}) //the below will parse the data thats part of the response if it is in json format; returns a promise
const responseData = await response.json();
if(!response.ok){
console.log("Something went wrong")
}
const results = [];
for (const id in responseData){
results.push({
id:id,
idCard: responseData[id].idCard,
name: responseData[id].name,
surname: responseData[id].surname,
email: responseData[id].email,
});
this.results = results;
}
}catch(error){
console.log(error);
}
},
},
//when component is fully initialised call method
mounted(){
this.getData();
}
}
</script>
the form in question
what it should look like

Highlight newly inserted row in Vue.js

I am fetching the JSON data(Orders) from REST API and displaying in a dynamic HTML table using Vue js. I have a "Print" button for each row in the table. The purpose of the button is printing the data of the row in a structure, basically a bill.
For that, I want to highlight the newly added row until the Print button is clicked by the user. How do I achieve this?
I'm refreshing the table every minute.
This is my code.
<tr v-for="orders, index in orders">
<th scope="row">{{ index + 1 }}</th>
<td>{{ orders.id }}</td>
<td>{{ orders.billing.first_name + " " +orders.billing.last_name }}</td>
<td>{{ orders.date_created }}</td>
<td>{{ orders.billing.phone}}</td>
<td>{{ orders.billing.address_1 + ", " + orders.billing.address_2 + ", " + orders.billing.city + orders.billing.postcode }}</td>
<td>{{ orders.line_items.name}}</td>
<td>{{ orders.total}}</td>
<td><button class="btn btn-primary" (click)="printBill(data)">Print</button></td>
</tr>
</tbody>
</table>
</div>
<script>
var app = new Vue({
el: '#app',
data: {
orders: []
},
mounted: function() {
axios.get('https://localhost/Site/wp-json/wc/v3/orders?consumer_key=KEY&consumer_secret=KEY1')
.then(response => {
this.orders = response.data;
console.log(response);
})
.catch(error => {
console.log(error);
});
},
})
</script>

I wrote a small example, have a look:
<template>
<div id="app">*
<tr
v-for="(order, index) in orders"
:key="index"
:class="{highlight: orders[index].isPrinted === undefined}"
>
<th scope="row">{{ index + 1 }}</th>
<td>{{ order.name }}</td>
<td>{{ order.something}}</td>
<td>
<button class="btn btn-primary" #click="printBill(index)">Print</button>
</td>
</tr>
</div>
</template>
<script>
export default {
name: "App",
data() {
return {
orders: []
};
},
methods: {
printBill(index) {
//code to print the bill
//change flag
this.$set(this.orders[index], "isPrinted", true);
}
},
mounted() {
//axios request - data sample
this.orders = [
{
name: "first",
something: "whatever"
},
{
name: "second",
something: "whatever"
},
{
name: "third",
something: "whatever"
},
{
name: "fourth",
something: "whatever"
},
{
name: "fifth",
something: "whatever"
}
];
}
};
</script>
<style>
.highlight {
background-color: blue;
color: white;
}
th {
width: 20%;
}
td {
width: 20%;
}
</style>
You can run it here.
As you can see that I am adding a flag to elements in orders array whenever printBill method runs.
By tracking newly added property we can conditionally display highlight class.

Add an isPrinted flag to each row of data, making sure you retain this if rows had been previously flagged. Also, call the API every minute.
mounted: function() {
// Call the API the first time
this.refreshData()
// Then call the API every minute
this.setIntervalId = setInterval(this.refreshData, 60000)
},
beforeDestroy: function() {
// Stop refreshing data after the component is destroyed!
clearInterval(this.setIntervalId)
}
methods: {
// Extract refresh logic into a method
refreshData () {
axios.get('https://localhost/Site/wp-json/wc/v3/orders?consumer_key=KEY&consumer_secret=KEY1')
.then(response => {
// Note the orders we previously flagged as printed, so we can reapply the flag after refreshing
const previouslyFlaggedIds = this.orders.filter(x => x.is_printed).map(x => x.id);
this.orders = response.data.map(x => ({...x, is_printed: previouslyFlaggedIds.find(y => y === x.id) != null}));
})
.catch(error => {
console.log(error);
});
}
}
Use this to style the rows
<tr
v-for="(order, index) in orders"
:key="order.id"
:class="{highlight: !order.is_printed}"
>
Set is_printed when rows are printed.
<td><button class="btn btn-primary" #click="printBill(order)">Print</button></td>
methods: {
printBill(order) {
order.is_printed = true
}
}

Laravel Eloquent ORM Pagination + Vue.js Component

I am working on this Laravel Project where I load a component activities-table with the main Vue instance data called from an API where I use Eloquent ORM Pagination. But the ActivitiesTable.data is undefined:
So, first I have my API on http://app.local/api/activities
public function getActivities()
{
$activities = Activity::orderBy('created_at', 'desc')->paginate(100);
foreach($activities as $k => $activity)
{
$data = [
'user' => isset($activity->user) ? $activity->user->name : NULL,
'avatar' => isset($activity->user) ? $activity->user->avatar : NULL,
'ip' => $activity->remote_addr,
'country' => $activity->country,
'referer' => $activity->referer,
'action' => $activity->request_uri,
'date' => $activity->created_at->toDateTimeString(),
'timeago' => $activity->created_at->diffForHumans()
];
$activities[$k]->custom_data = $data;
}
return $activities;
}
Then I have my main Vue instance method where I call the API on the file app.js:
loadActivities: function(page = 1) {
axios.get('/api/activities?page=' + page)
.then(function (response) {
app.activities = response.data;
});
},
So this is how activities seems on Vue Tool:
So, this is my component that is already registered on app.js:
<template>
<!-- Activities -->
<table id="activities">
<thead>
<tr>
...columns...
</tr>
</thead>
<tbody>
...data...
</tbody>
</table>
<!-- /Activities -->
</template>
<script>
module.exports = {
props: {
rows: {
}
},
data: function() {
return {
data: this.rows
}
},
created: function() {
},
methods: {
paginate: function(page) {
}
}
}
</script>
<style scoped>
</style>
And then here is the <activities-table> component:
<activities-table
:rows="this.activities"
></activities-table>
I get the result in the same Vue Tool:
I already tried to assign this.data = this.rows in the created hook, or try different lifecycle hooks but always is undefined or an empty array.
This is what console.log(this.data) on the Vue component displays:
What am I doing wrong? Thanks in advance.
