Loop over method in vue - vuejs2

I want to be able to loop over all the invoices for a given client-year-month
I use django_filter in DRF to do some filtering on the backend, my endpoints look like this:
all invoices: http://127.0.0.1:8000/invoices/
filters: http://127.0.0.1:8000/invoices/?client=2&year=2020&month=5
I have a method that gets the results based on the filter, and a watch property for retrieving the data at the right time, in this case when a month is chosen.
methods: {
retrieveResults() {
this.$axios.$get('/invoices/', {
params: {
client: this.client,
month: this.month,
year: this.year,
},
});
},
},
watch: {
month: {
handler: 'retrieveResults',
},
},
The response I get looks like this (simplified):
[{
"id":119,
"client":2,
"invoice_id":"2020001",
"order_date":"2020-05-07",
},
{
"id":120,
"client":2,
"invoice_id":"2020002",
"order_date":"2020-05-07",
}]
Everything is working as expected, I see the right results in my network tab depending on the choices, my question is how do I v-for loop over this? I've tried numerous things, nothing has worked so far.
I tried wrapping the retrieveResults in a vuetify v-data-table, without success.

Something like this:
// in a template:
<div v-for="invoice in invoices" :key="invoice.id">
// here is a component(s) for showing invoice content
</div>
...
// in a component:
data: {
return {
invoices: []
}
},
methods: {
async retrieveResults() {
const { data: invoices} = await this.$axios.$get('/invoices/', {
params: {
client: this.client,
month: this.month,
year: this.year,
},
});
this.invoices = invoices
}
}

How can I put a data inside the <template> in a component with Vue

I am trying to do a pagination but I can not put the dynamic total I am doing like this:
<v-pagination v-model="currentPage"
:page-count="total"
:classes="bootstrapPaginationClasses"
:labels="paginationAnchorTexts"
></v-pagination>
How you can see the total os in the :page-count, it is a dynamic total because I am getting data from database, my vue code is this one:
<script>
import vPagination from 'vue-plain-pagination';
export default {
created() {
this.getPosts();
},
methods: {
getPosts() {
fetch('/api/bank')
.then(response => response.json() )
.then(json => {
this.posts = json.data.data;
this.total = json.data.last_page;
this.current_page = json.data.current_page;
});
}
},
components: { vPagination },
data: function() {
return {
postsSelected: "",
posts: [],
currentPage: 1,
total: this.total,
bootstrapPaginationClasses: {
ul: 'pagination',
li: 'page-item',
liActive: 'active',
liDisable: 'disabled',
button: 'page-link'
},
paginationAnchorTexts: {
first: 'Primera',
prev: '«',
next: '»',
last: 'Última'
}
}
}
}
</script>
How you can see I am using fetch to get the data from database and then I am split it in different information like total and the I am using this information inside the data: function() {}.
How you can tell total it's like this: total: this.total because I want to get the total number but when I do that I am getting this error:
[Vue warn]: Invalid prop: type check failed for prop "pageCount". Expected Number with value NaN, got Undefined
and I think that it is because:
total: this.total in the data function() {} is bad or:
how can I put the dynamic variable total inside the
How could I fix it?
Thanks!
If you want to know the data retrieved from the API, you can console log the data returned like this:
getPosts() {
fetch('/api/bank')
.then(response => response.json() )
.then(json => {
console.log(json.data)
this.posts = json.data.data;
this.total = json.data.last_page;
this.current_page = json.data.current_page;
});
}
Also, you should not have data attribute and props attribute with the same name! So change the total data attribute to another name and initialize it with a value of 0 instead.
In fact, you don't need to care about passing the Prop total at all as your method getPosts is not dependent on the Prop! So you may just have total: 0 in data and that should fix your issues

How to build a VUE link in a method using vue-router

I'm new using VUE.JS and I'm in love with it! I love the vue-router and router-link! They are awesome!
Now I have a table populated by data coming from axios and I would like to build a link using this data in a custom method to have the team name clickable.
Here the template:
<BootstrapTable :columns="table.columns" :data="table.data" :options="table.options"></BootstrapTable>
Axios returns ID, name and other data used to update the table as here
Basically, I need to update the values in my table using the axios's received data. Something like:
team: '<a v-bind:href="club/'+team.id+'">'+team.team+'</a>',
or
team: '<router-link :to="club/'+team.id+'">'+team.team+'</router-link>',
But obviously it dosn't works...
How can a build a link?
I fixed it using custom column event and formatter in columns table setting:
{
field: 'match',
title: 'Match',
formatter (value, row) {
return `${value}`
},
events: {
'click a': (e, value, row, index) => {
e.preventDefault();
this.$router.push(`/matches/${row.pos}`)
}
}
},
Another solution:
Just in case of JSON code having links instead of table config is adding click listener in mounted() and a well formatted dataset in JSON HTML link:
team: "<a href=\"/club/"+team.id+"\" data-to='{\"name\": \"team\",\"params\":{\"teamId\":"+ team.id+"}}'>"+ team.team+"</a> "+userCode
Here the listener:
mounted() {
window.addEventListener('click', event => {
let target = event.target;
if (target && target.href && target.dataset.to) {
event.preventDefault();
const url = JSON.parse(target.dataset.to);
//router.push({ name: 'user', params: { userId: '123' } })
this.$router.push(url);
}
});
}
This might be shorter solution for your issue :
routes = [
{
component : 'club',
name : 'club',
path : '/club/:teamid'
}
]
<a #click="$router.push({ name: 'club', params: { teamid: team.id}})">team.team</a>

Getting documents with ID from firstore collection

While using Firestore, vuefire, vue-tables-2, I stuck getting document's id.
My data structure is as below.
Here is my code.
<v-client-table :columns="columns" :data="devices" :options="options" :theme="theme" id="dataTable">
import { ClientTable, Event } from 'vue-tables-2'
import { firebase, db } from '../../firebase-configured'
export default {
name: 'Devices',
components: {
ClientTable,
Event
},
data: function() {
return {
devices: [],
columns: ['model', 'id', 'scanTime', 'isStolen'],
options: {
headings: {
model: 'Model',
id: 'Serial No',
scanTime: 'Scan Time',
isStolen: 'Stolen YN'
},
templates: {
id: function(h, row, index) {
return index + ':' + row.id // <<- row.id is undefined
},
isStolen: (h, row, index) => {
return row.isStolen ? 'Y': ''
}
},
pagination: {
chunk: 5,
edge: false,
nav: 'scroll'
}
},
useVuex: false,
theme: 'bootstrap4',
template: 'default'
}
},
firestore: {
devices: db.collection('devices')
},
};
My expectation is devices should id property as vuefire docs.
But array this.devices didn't have id field even if I check it exist it console.
Basically, every document already has id attribute, but it's non-enumerable
Any document bound by Vuexfire will retain it's id in the database as
a non-enumerable, read-only property. This makes it easier to write
changes and allows you to only copy the data using the spread operator
or Object.assign.
You can access id directly using device.id. But when passing to vue-tables-2、devices is copied and lost id non-enumerable attribute.
I think you can workaround using computed property
computed: {
devicesWithId() {
if (!this.devices) {
return []
}
return this.devices.map(device => {
...device,
id: device.id
})
}
}
Then, please try using devicesWithId in vue-tables-2 instead.

Why it is hard to use vue-i18n in vue data() (why it is not reactive)

I am using vue-i18n in a vue project. And I found it really confusing when using some data in vue data with i18n. Then if I change locale, that data is not reactive. I tried to return that data from another computed data but anyways it is not reactive because i18n is written in data. *My situation - * I want to show table with dropdown(list of columns with checkbox) above it. When user checks a column it will be showed in table if unchecks it won't. It is working fine until I change locale. After changing locale table columns is not translated but dropdown items is reactively translated and my code won't work anymore. Here is some code to explain better: In my myTable.vue component I use bootstrap-vue table -
template in myTable.vue
<vs-dropdown vs-custom-content vs-trigger-click>
<b-link href.prevent class="card-header-action btn-setting" style="font-size: 1.4em">
<i class="fa fa-th"></i>
</b-link>
<vs-dropdown-menu class="columns-dropdown">
<visible-columns :default-fields="columns" #result="columnListener"></visible-columns>
</vs-dropdown-menu>
</vs-dropdown>
<b-table class="generalTableClass table-responsive" :fields="computedFieldsForTable">custom content goes here</b-table>
script in myTable.vue
data(){
return {
fieldsForTable: [];
}
},
computed: {
computedFieldsForTable () {
return this.fieldsForTable;
},
columns() {
return [
{
key: 'id',
label: this.$t('id'),,
visible: true,
changeable: true
},
{
key: 'fullName',
label: this.$t('full-name'),,
visible: true,
changeable: true
},
{
key: 'email',
label: this.$t('email'),,
visible: true,
changeable: true
}
]
}
},
mounted () {
this.fieldsForTable = this.filterColumns(this.columns);
},
methods: {
filterColumns(columns = []) {
return columns.filter(column => {
if (column.visible) {
return column
}
})
},
columnListener ($event) {
this.fieldsForTable = this.filterColumns($event)
}
}
Can someone give me some advice for this situation ?
*EDIT AFTER SOME DEBUGGING: I think when filtering columns(in computed) and returning it for fieldsForTable inside filterColumns(columns) method, it actually returning array(of objects) with label='Label Name' not label=this.$t('labelName'). So after filtering the new array has nothing to do with vue-i18n. My last chance is reloading the page when locale changes.
Trying modify computedFieldsForTable as follows. You need to reference this.columns in computedFieldsForTable, so that Vue can detect the change of labels in this.columns.
computedFieldsForTable () {
return this.filterColumns(this.columns);
},
EDITED: put your this.columns in data. Then
columnListener ($event) {
this.columns = $event;
}
I hope i didn't misunderstand what you mean.
EDITED (again):
Maybe this is the last chance that I think it can work. Put columns in computed() still and remove computedFieldsForTable. Finally, just leave fieldsForTable and bind it on fields of <b-table>.
watch: {
columns(val) {
this.fieldsForTable = this.filterColumns(val)
}
},
method: {
columnListener ($event) {
this.fieldsForTable = this.filterColumns($event)
}
}
However, I think it is better and easier to reload page whenever local change. Especially when your columns have a more complex data structure.

Vuejs2 issue passing data changes between children

Another issue with a project I am working on.
I have the following vuejs2 parent-child structure
Parent app
child product-list
product
product-image
colour-select
Within the product template I initiate the sibling components
The colourSelect component takes a comma delimited string and turns it into a drop down list. Whenever the selected option changes it emits the colour back to the product component which has a data variable "colour"
This appears to work fine.
The product-image component takes the product colour as a prop.
Whenever the colour changes I want the product-image component to detect it and trigger it to go get the relevant image. But its not detecting the change in colour.
Vue.component('product', {
props: ['productID', 'images', 'product'],
data: function () {
return {
colour: 'Navy',
}
},
computed: {
returnColour: function (colour) {
// this.colour = colour
//return colour
}
},
template: '<transition name="list"><li class="moving-item" id="productID">' +
'<product-image :productID="productID" :images="getImage(product.productID)" :colour="colour"></product-image>' +
'<colourSelect :colours="product.colour" :productID="product.productID" v-on:set-colour="setColour(colour)"></colourSelect>' +
'</li></transition>',
methods: {
getImage: function (listItemId) {
var images = this.images.filter(function (item) {
return returnCleanedData(item.Products_x003a_ID) === listItemId
})
},
setColour: function (colour) {
console.log('in main colour emit')
this.colour = colour
console.log(this.colour)
}
}
});
Vue.component('colourSelect', {
props: ['productID', 'colours', 'set-colour'],
template: '<select v-bind:id="getID()" class="form-control input-xs" :disabled=" isActive" v-bind:class="{disabledSelect: isActive}" v-on:click="setColour(productID)">' +
'<colourOption v-for="colourItem in colourArray">{{ colourItem.colour }}</colourOption>' +
'</select>',
data: function() {
return {
isActive: false
}
},
computed: {
colourArray: function () {
//splits data and applies it to the select
}
},
methods: {
getID: function () {
return 'colourSelect' + this.productID;
},
**setColour: function (productID) {**
//yeah used jquery here
var colour = $('#colourSelect' + productID).val()
this.$emit('set-colour', colour)
}
}
});
Vue.component('product-image', {
props: ['productID', 'images', 'colour'],
template: '<p><slot></slot><img :src="getImage(productID, images, colourSelected)" class="productImagePosition img-responsive img-rounded"></img></p>',
data: function () {
return {
isActive: false,
selectedColour: this.colour
}
},
computed: {
colourSelected: function () {
console.log('colour change detected')
return this.colour
}
},
methods: {
getID: function (test) {
return 'colourSelect' + this.productID;
},
getImage: function (listItemId, images, colour) {
console.log('selected colour')
console.log(colour)
//filter images to the specific colour and return link
},
}
});
The issue appears to be related to this line in the product template
v-on:set-colour="setColour(colour)"
When the child component emits the set-colour data back, the product is correctly running this method. But the product-image doesn't detect the change to its prop.
If i change the line to v-on:set-colour="setColour()" it will actually detect the change in the product-image but will error due to no data being passed.
Within the product-image component I have tried referencing a computed value (colourSelected) instead of the prop within the template which has no effect.
Any ideas?
Thanks
On product-image add a watcher to the colour prop:
watch: {
colour(value) {
// make changes here
},
},
