How to get next data with pagination in Quasar Framework? - vue.js

I want to use datatable with server pagination in Quasar Framework, I already try the example, but I didn't get it if my Rest API return this kind of JSON,
{
"count": 808,
"next": "http://localhost:8000/v1/assets?expand=village.subdistrict.city.province&page=2",
"previous": null,
result: [
{ id: 1, name: 'Frozen Yogurt', calories: 159, fat: 6.0, carbs: 24, protein: 4.0, sodium: 87, calcium: '14%', iron: '1%' },
{ id: 2, name: 'Ice cream sandwich', calories: 237, fat: 9.0, carbs: 37, protein: 4.3, sodium: 129, calcium: '8%', iron: '1%' },
{ id: 3, name: 'Eclair', calories: 262, fat: 16.0, carbs: 23, protein: 6.0, sodium: 337, calcium: '6%', iron: '7%' },
{ id: 4, name: 'Cupcake', calories: 305, fat: 3.7, carbs: 67, protein: 4.3, sodium: 413, calcium: '3%', iron: '8%' },
]
}
I think the documentation doesn't explain this case
How can I use 'next' to fetch the next page ?

How to change text to all in v-table vuetify?

Currently I can change the number of options but what I don't know is how to change all to Todos, What can I do to change it ?
<v-data-table
:footer-props="{'items-per-page-options':[15, 30, 50, 100, -1]}"
...>
Edit:

You can add one more property in :footer-props attribute value object.
'items-per-page-all-text':'Todos'

How can I iterate between dynamic columns with v-slot in Vuetify

I have dynamically changing columns in data-table. For example an col1, col2, col3-value column. How can I made dynamically the <template v-slot:item.col1="item"> and <template v-slot:item.col2="item">....

You can add multiple templates in your table. So you can just define one for every col in your table.
Here is a working example with the deserts example in the vuetify API.
<template>
<v-data-table
:headers="headers"
:items="desserts"
:items-per-page="5"
class="elevation-1"
>
<template v-slot:item.calories=" { item }">
{{ item.calories.toFixed(2) }}
</template>
<template v-slot:item.fat=" { item }">
{{ item.fat.toFixed(1) }}
</template>
<template v-slot:item.carbs=" { item }">
{{ item.carbs.toFixed(3) }}
</template>
</v-data-table>
</template>
<script>
export default {
name: "Hello",
data () {
return {
headers: [
{
text: 'Dessert (100g serving)',
align: 'start',
sortable: false,
value: 'name',
},
{ text: 'Calories', value: 'calories' },
{ text: 'Fat (g)', value: 'fat' },
{ text: 'Carbs (g)', value: 'carbs' },
{ text: 'Protein (g)', value: 'protein' },
{ text: 'Iron (%)', value: 'iron' },
],
desserts: [
{

calories: 159,
fat: 6.0,

Vuetify data table show last page when loaded

How can I add prop "page" so that the table shows the last page when loaded. The number of items is variable. Should I do items.lenght/items-per-page or is there any better way?
<v-data-table
:headers="headers"
:items="items"
:search="search"
multi-sort
must-sort
:sort-by="['date', 'number']"
class="elevation-1"
:items-per-page="10"
:footer-props="{
showFirstLastPage:true,
}"
:loading="loading"
height="540"
></v-data-table>

#grimdbx as per your above comments it is correct, you've taken the right try, you just need to set the page property with the computed result
The computed property always retruns the last page number on page load
computed: {
lastPage() {return Math.ceil(this.items.length/10);}
}
here instead of this.itemsPerPage you can replace with 10, since you
have harcoded the items per page as per your above code
the final working code looks like
<div id="app">
<v-app id="inspire">
<v-data-table
:headers="headers"
:items="desserts"
:items-per-page="5"
class="elevation-1"
:page="lastPage"
></v-data-table>
</v-app>
</div>
new Vue({
el: '#app',
vuetify: new Vuetify(),
computed: {
lastPage() {return Math.ceil(this.desserts.length/5);}
},
data () {
return {

{
text: 'Dessert (100g serving)',
align: 'start',
sortable: false,
value: 'name',
},
{ text: 'Calories', value: 'calories' },
{ text: 'Fat (g)', value: 'fat' },
{ text: 'Carbs (g)', value: 'carbs' },
{ text: 'Protein (g)', value: 'protein' },
{ text: 'Iron (%)', value: 'iron' },

v-data-table error cannot create property isRootInsert with remote data

Using documentation example of v-data-table getting Error TypeError: Cannot create property 'isRootInsert' on string ... using latest Vuetify 2.3.x -- unable to reproduce in codepen.

Make sure in your Vue files to import components.
import { Vue, Component } from 'vue-property-decorator'
After you import your components from vue-property-decorator in all your Vue files.
Make sure you register your components in all your Vue files as well like the snippet below
#Component({
components: {
},
...
})

Make sure all your pages in router must add #Component.
if one of pages doesn't contain #Component,
it will not work out.

Vuetify table doesn't accept input

Is it possible to add vuetify inputs to vuetify table?
The only way that I found to add data to a table is by using JSON content.
Is it possible to overide/config vuetify so it adds data to the table like Material Design does?
This is how I call my table
<template>
<v-data-table
:headers="headers"
:items="desserts"
:items-per-page="5"
class="elevation-1"
></v-data-table>
</template>
This is how I add Data to my table
<script>
export default {
data () {
return {
headers: [
{
text: 'Dessert (100g serving)',

sortable: false,
value: 'name',
},
{ text: 'Calories', value: 'calories' },
{ text: 'Fat (g)', value: 'fat' },
{ text: 'Carbs (g)', value: 'carbs' },
{ text: 'Protein (g)', value: 'protein' },
{ text: 'Iron (%)', value: 'iron' },
],
