How to pass a component to render in props in Vue Js? - vue.js

I have a situation where i need to render data cell synamically
where tableProps contain all columns and dataProps.
tableProps: {
cols: [{
cellProps: {
class: "as"
},
cellRenderer: ((data) => {
return <a onlick = {
this.onDataClick
}
class = "btn btn-link" > {
data.name
} < /a>
}).bind(this),
dataKey: "name",
dataType: String,
label: "Name",
sortable: true
}
],
enableSelect: true,
onPageChange: this.onPageChange,
onSelect: (selectedRow) => console.log("selectedRow", selectedRow),
onSelectAll: (data) => console.log("slectAllClick", data),
page: 0,
rowProps: {
onClick: (event, rowData) => {
this.onClick(rowData);
}
},
rowsPerPage: 5,
title: "Nutrition"
}
There is a cell renderer where data can be passed to render custom data like buttons anchor etc..

the solution has been found, instead of sending a function, scoped slots can be used to render dynamic contents for each cell. Thank you for showing interest.
**Table.Vue(child, generic-table)**
<table class="table table-bordered">

display a foreign data in a table vuejs

I am creating a page, in which a section called product, I show data and in this I have a data called id_categoria, where instead of showing the id I want to show the name of that category in question, this data is in the table of categories and in the product table I have the id. I already managed to show the data, but not this, besides that I managed to save and edit it in question, it is only necessary in show.
When working with vuejs I saw that you have to use a v-if but I do not know how to do it, or at least the attempts I have made have been wrong.
this is the code of the table where I show the data
<div class="card-body table-responsive">
<table id="example1" class="table table-bordered table-striped">
<thead>
<tr>
<th>id_producto</th>
<th>imagen</th>
<th>código</th>
<th>producto</th>
<th>categoria</th>
<th>stock</th>
<th>precio_compra</th>
<th>precio_venta</th>
<th>fecha</th>
<th colspan="2" class="text-center">Acciones</th>
</tr>
</thead>
<tbody>
<tr v-for="pro in productos" :key="pro.id_productos">
<th>{{pro.id_productos}}</th>
<td>
<img :src="pro.imagen" class="img-circle elevation-2" alt="Product Image" width="60" />
</td>
<td>{{pro.codigo}}</td>
<td>{{pro.producto}}</td>
<td>{{pro.id_categoria}}</td>
<td>{{pro.stock}}</td>
<td>{{pro.precio_compra}}</td>
<td>{{pro.precio_venta}}</td>
<td>{{pro.fecha}}</td>
<td class="text-center">
<button #click="modificar=true; abrirModal(pro)" type="button" class="editar btn btn-primary"><i class="fa fa-pencil-alt"></i></button>
</td>
<td class="text-center">
<button #click="eliminar(pro.id_productos,pro.producto)" type="button" class="eliminar btn btn-danger" data-toggle="modal" data-target="#modalEliminar"><i class="fas fa-dumpster-fire"></i></button>
</td>
</tr>
</tbody>
<tfoot>
<tr>
<th>id_producto</th>
<th>imagen</th>
<th>código</th>
<th>producto</th>
<th>categoria</th>
<th>stock</th>
<th>precio_compra</th>
<th>precio_venta</th>
<th>fecha</th>
<th colspan="2" class="text-center">Acciones</th>
</tr>
</tfoot>
</table>
</div>
and this is the script to bring the info to me
<script>
import axios from "axios";
export default {
watch: {
$route: {
immediate: true,
handler(to, from) {
document.title = to.meta.title || 'Productos';
}
},
},
data() {
return{
productosdatos:{
id_producto: "",
codigo: "",
producto: "",
stock: "",
precio_compra: "",
precio_venta : "",
id_categoria: "",
},
id: 0,
modificar: true,
modal: 0,
tituloModal: '',
productos:[],
categorias:[],
}
},
methods: {
async listarcategorias(){
const res = await axios.get('http://localhost:8000/categoria/');
this.categorias = res.data;
console.log(this.categorias)
},
async listar(){
const res = await axios.get('http://localhost:8000/productos/');
this.productos = res.data;
console.log(this.productos)
},
cerrarModal(){
this.modal = 0;
}
},
created() {
this.listar();
}
}
</script>
as you can see I have a variable called products, where is the id_category corresponding to the product, and categories where I bring all the category info.
the table looks something like this:
how can I make it not show the id of the category but the name of the category in question ?
pd: the category data is received in json as follows:
{
"id_categoria": 8,
"categoria": "Electrodomesticos",
"fecha": "2021-10-24 13:55:00"
}
thank you if you can help me to show the name of the category thank you
You can implement a function like this:
const findCategory = (id)=>{this.categorias.find(category=>category.id_categoria===id)?.categoria}
And in the template:
<td>{{findCategory(pro.id_categoria)}}</td>
Only one small change. In your code you have to edit. pro.id_categoria to pro.categoria. see comment inline.
<tr v-for="pro in productos" :key="pro.id_productos">
<th>{{pro.id_productos}}</th>
<td>
<img :src="pro.imagen" class="img-circle elevation-2" alt="Product Image" width="60" />
</td>
<td>{{pro.codigo}}</td>
<td>{{pro.producto}}</td>
// this line
<td>{{pro.id_categoria}}</td>
// edit to
<td>{{ pro.categoria }} </td>

Vue Component data object property's behavior not as expected [Solved]

I have an app with a child component that makes a call to an api for a player's season stats. You click on the players name and I emit click event to child from Parent component. The problem is when you click on Players name from parent all instances of the child component are revealed. I just want the one player. I thought because I have a showComponent instance for each child by toggling this.showComponent in child would get my expected behavior but no.
Code:
Parent-
methods: {
emitPlayerSeasonStatsClicked: function(event) {
const target = event.target;
EventBus.$emit("showPlayerTemplateClicked", target);
}
},
template: `
<div v-for="playerStats in props_box_game_scores[index].data.gameboxscore.awayTeam.awayPlayers.playerEntry">
<tr v-if="playerStats.player.Position === 'P'" class="d-flex" v-bind:data-player-id="playerStats.player.ID">
<td class="col-4 justify-content-center" scope="row" title="Click for Season Stats">
{{playerStats.player.FirstName}} {{playerStats.player.LastName}}
<span v-if="playerStats.stats.Wins['#text'] === '1'">(W)</span>
<span v-else-if="playerStats.stats.Losses['#text'] === '1'">(L)</span>
<span v-else-if="playerStats.stats.Saves['#text'] === '1'">(S)</span>
</td>
<td class="col-2 justify-content-center" justify-content="center">
{{playerStats.stats.InningsPitched['#text']}}</td>
<td class="col-2 justify-content-center">{{playerStats.stats.RunsAllowed['#text']}}</td>
<td class="col-2 justify-content-center">{{playerStats.stats.PitcherStrikeouts['#text']}}</td>
<td class="col-2 justify-content-center">{{playerStats.stats.EarnedRunAvg['#text']}}
</td>
</tr>
<pitcher-season-stats v-bind:props_player_id="playerStats.player.ID"></pitcher-season-stats>
</div>
Child-
cumlativeStats: Vue.component("player-season-stats", {
props: ["props_player_id"],
data: function() {
return {
Hits: "",
HR: "",
RBI: "",
BattingAvg: "",
showComponent: false
};
},
mounted: function() {
EventBus.$on("showPlayerTemplateClicked", function(data) {
this.showComponent = !this.showComponent;
});
},
methods: {
retrievePlayerStats: function(playerId) {
const url = `https://api.mysportsfeeds.com/v1.2/pull/mlb/2019-regular/cumulative_player_stats.json?player=`;
const params = {
playerstats: "AB,H,HR,RBI,AVG",
force: true
};
...
template: `
<tr class="d-flex" v-if:showComponent>
<td #click="retrievePlayerStats(props_player_id)" class="col-4 justify-content-center" scope="row">
Season Stats</td>
</td>
<td class="col-2 justify-content-center" justify-content="center">

<td class="col-2 justify-content-center"> {{ BattingAvg }}</td>
<td class="col-2 justify-content-center">{{ RBI }}</td>
</tr>
` // End template
})
Any suggestions welcome. Sorry for the formatting.
**
Updated Working Solution:
**
Parent:
methods: {
emitPlayerSeasonStatsClicked: function($event) {
let playerId = $event.target.dataset.playerId;
EventBus.$emit("showPlayerTemplateClicked", playerId);

methods: {

if (playerId === this.props_player_id) {
this.loading = true;
this.showComponent = !this.showComponent;
this.retrievePlayerStats(playerId);
}
},
template: `
<transition name="fade">
<tr class="d-flex" v-if="showComponent">
<td v-if="!loading" class="col-4 justify-content-center" scope="row">
Season Stats</td>
</td>
<td class="col-2 justify-content-center" justify-content="center">
{{ Hits }}</td>
<td class="col-2 justify-content-center">{{ HR }}</td>
<td class="col-2 justify-content-center"> {{ BattingAvg }}</td>
<td class="col-2 justify-content-center">{{ RBI }}</td>
</tr>
</transition>
` // End template
})
};
The code provided doesn't actually call emitPlayerSeasonStatsClicked but I assume that's supposed to go on the <td> that includes the name.
If you write the click listener like this:
<td
class="col-4 justify-content-center"
scope="row"
title="Click for Season Stats"
#click="emitPlayerSeasonStatsClicked(playerStats.player.ID)"
>
Then include the id as part of the event emitted by the event bus:
emitPlayerSeasonStatsClicked: function(playerId) {
EventBus.$emit("showPlayerTemplateClicked", playerId);
}
Listening for this in the mounted would be:
mounted: function() {
EventBus.$on("showPlayerTemplateClicked", this.onShowPlayerTemplateClicked);
},
with method:
methods: {
onShowPlayerTemplateClicked: function(playerId) {
if (playerId === this.props_player_id) {
this.showComponent = !this.showComponent;
}
}
}
Assuming the player ids are unique that should be enough to get it working.
However...
The choice of an event bus to pass data to a child seems a poor one. There are several ways this could be done. One way would be to only create it when it's showing (external v-if). Another would be to use props. Yet another would be to use refs to call a method on the child.
I don't understand how your code ever toggled anything. The this value for the listener in mounted will not be the component. I've fixed that by moving it to a method, which Vue will bind correctly. Another reason to move this to a method is that it allows you to remove the listener when the component is destroyed.
v-if:showComponent is not a thing. I assume that should be v-if="showComponent".
Your <tr> elements seem to be immediate children of <div> elements. That isn't correct HTML for tables.

Vuejs2- Avoid repetition of select field options using vee-validate

Iam using vee-validate plugin for validation. In my form, there is a select field in the table. Rows will be added dynamically in the table. I don't want to select the same select(Description column) option again and again Image. Hence I want to throw an error like "Selected description already exists in a table" this using vee-validate. Kindly help me to solve this.
Here is my code:

Thanks in advance.
You're on the right track, but a couple changes need to be made. When you call this.$validator.extend, that only needs to be done once - when your component is created. It attaches the check method to the validator, so then every time you have the attribute v-validate="'required|check'" in your HTML, it will run that check method.
In your check validator, you need to answer the question "is this value already selected". The answer is to go through the this.rows and see if any of them have the same billChgDesc property. Because this is in Vue, by the time the validator gets run, the row in question already does have that value, so you want to check if MORE than one row have that value. So, something like this:
mounted() {
var self = this;
this.$validator.extend('check', {
getMessage: field => '* Selected ' + field + ' already exists',
validate: function(value){
return (self.rows.filter(function(v){
return v.billChgDesc == value;
}).length <= 1);
}
});
}
This validator returns true if only one item has the given value. I'm using the built-in filter method of Array (see docs).
You can see an example of this all working here: https://jsfiddle.net/ryleyb/f9q50wx4/1/

vue.js does not correctly rerender compared to the vue instance object

I have a small issue with my vue template. The code is the following :
<template>

<div class="panel-heading">{{noeud.name}}</div>

<input type="button" class="btn btn-primary" #click="addNoeudProximite" value="Ajouter"/>
</td>
</tr>
</tbody>

</div>
</div>
</template>
<script>
export default {
props: ['pnoeud', 'pnoeuds'],
data: function(){
return {

new_weight:0,
new_noeud:0,
noeud:this.pnoeud,
noeuds:this.pnoeuds,
weightSorted:this.pnoeud.weightSorted
}
},
mounted() {
},
methods:{
delete_final(macro_zonning_noeud_id_2){
axios.delete("/macrozonning/proximite/",{
params:{
macro_zonning_noeud_id_2:macro_zonning_noeud_id_2,
macro_zonning_noeud_id_1:this.noeud.id
}
}).then((res) => {
Vue.delete(this.weightSorted, String(macro_zonning_noeud_id_2));
})
},
update_line(nb_points){
this.points_restants = this.points_restants - nb_points;
this.points = this.points + nb_points;
},
addNoeudProximite(){

'weight': this.new_weight
}).then((res) => {
Vue.set(this.weightSorted, String(this.new_noeud), res.data);
});
}
}
}
</script>
When the function delete_final is executed on the last item of my list, the view is correctly rerendered as the last item of my list is removed. But when I try to remove the first item of my list then the view rerenders but the the last item has been removed. When I check the Vue object in devtools, it does not reflect the new view, but it reflects the action taken (my first item has been removed).
If you have any idea where this problem comes from it would be awesome.
Thanks a lot community
Use a key attribute on the element you are rendering with v-for so that vue can exactly identify VNodes when diffing the new list of nodes against the old list. See key attribute
<tr> v-for="noeud_poids in weightSorted" :key="noeud_poids.id" </tr>

How to edit particular row in a table by popping a form modal in vuejs?

I am using a modal form to add new details to the row of a table. After adding details, I’m just adding edit and delete buttons at the end of it. Now here delete button is working fine. How to edit a row of a table by popping replicate of form modal by clicking “edit” button in a row.
Here’s my code:
<div class="layout-padding">
<div
class="item item-link"
v-for="modal in types"
#click="$refs[modal.ref].open()"
>
<i class="item-primary">add</i>
<div class="item-content has-secondary">
<div>{{modal.label}}</div>
</div>
</div>
</div>
<q-modal ref="maximizedModal" class="minimized" :content-css="{padding: '50px'}">
<div class="main">
<label>Enter Your Name:</label>
<input id="name" name="name" type="text" placeholder="Enter your Name" v-model="YourName">
<br>
<label>I am:</label>
<input type="radio" id="Male" value="male" v-model="picked">
Male
<input type="radio" id="Female" value="female" v-model="picked">
Female
<br>
<div class="button">
<button class="red" #click="$refs.maximizedModal.close()">Close</button>
<button class="blue" v-on:click="sub" #click="$refs.maximizedModal.close()">Submit</button>
</div>
</div>
</q-modal>
<table>
<thead>
<th>Name</th>
<th>Gender</th> </thead>
<tbody class="result">
<tr v-for="(h, index) in final">
<td v-for="(value, key, index) in h">
{{ value }}
</td>
<td><button id="edit" class="green edit" v-for="modal in types"
#click="ed(h, index);$refs[modal.ref].open()" type="submit">EDIT</button></td>
<td><button id="delete" class="red delete" v-on:click="del(index)" type="submit">Delete</button></td>
</tr>
</tbody>
</table>
And my script is:
export default {
data () {
return {YourName: '',
details: [],
final: [],
types: [
{
label: 'Add Details',
ref: 'maximizedModal'
}
],
position: 'bottom'
}
},
methods: {
sub: function () {
this.details = {
'name': this.YourName,
'gender': this.picked,
}
this.ed()
if (index === '[object MouseEvent]') {
this.final.push(this.details)
}
if (index > -1) {
this.final.splice(index, 1, this.details)
}
else {
alert('else')
alert(JSON.stringify(this.details))
this.final.push(this.details)
}
},
del: function (index) {
this.$delete(this.final, index)
},
ed: function (details, index) {
return index
}
}
}
If edit button is clicked, the same row should be edited. I don’t know how to proceed further. Please, guide me.
Using the 'splice' can able to modify the given array of object.
Can simply include this inside an 'if' loop:
this.final.splice(this.indi, 1, this.details)
