Using vuetify card like bootstrap cards columns - vuejs2

I need a way to use list of v-card from Vuetify like Bootstrap Card Columns
Possible solution:
Pardon me, I couldn't plunkr the code :(
This is what I did.
Update: Unfortunately this messes up with the v-ripple directive
<template>
<v-container grid-list-md>
<div class="v-card-columns">
<v-card tile v-for="post in posts" :key="post.id">
<v-card-title primary-title>
<h3 headline>
{{post.title}}
</h3>
</v-card-title>
<v-card-text>
{{post.body}}
</v-card-text>
</v-card>
</div>
</v-container>
</template>
<script>
import axios from "axios";
export default {
name: "All",
data() {
return {
posts: []
}
},
mounted() {
axios
.get('https://jsonplaceholder.typicode.com/posts')
.then(res => {
this.posts = res.data
})
}
}
</script>
<style scoped>
.v-card-columns .v-card {
margin-bottom: 0.75rem;
}
#media (min-width: 576px) {
.v-card-columns {
-webkit-column-count: 3;
-moz-column-count: 3;
column-count: 3;
-webkit-column-gap: 1.25rem;
-moz-column-gap: 1.25rem;
column-gap: 1.25rem;
orphans: 1;
widows: 1;
}
.v-card-columns .v-card {
display: inline-block;
width: 100%;
}
}
</style>

Horizontally draggable quasar q-cards using vue.draggable.next

I've seen a few 'solutions' online about this but to no avail for us. We're working with the quasar framework and trying to setup a horizontally wrapped set of that are are draggable (for re-ordering). Below is the basic stub of the code we're working with to get this going. However, we're not able to get the cards to layout horizontally everything is stacked in a list. What are we doing wrong?
<template>
<draggable
v-model="items"
group="items"
direction="horizontal"
item-key="id"
#start="drag = true"
#end="drag = false"
>
<template #item="{ element }">
<q-card class="card">
<q-img src="~assets/temp/bb-auto.png" :alt="`Image ${element.name}`">
<div class="absolute-bottom text-subtitle2 text-center">
Image {{ element.name }}
</div>
</q-img>
</q-card>
</template>
</draggable>
</template>
<script setup lang="ts">
import { ref } from 'vue';
import draggable from 'vuedraggable';
const drag = ref(false);
const items = ref([
{ name: 'item1' },
{ name: 'item2' },
{ name: 'item3' },
{ name: 'item4' },
{ name: 'item5' },
]);
</script>
<style scoped>
.card {
max-height: 200px;
max-width: 200px;
display: flex;
}
</style>
Turns out our overall structure was incorrect and once we sorted that out was able to back this into the draggable. We then had to basically treat our as the row.
<template>
<draggable
v-model="items"
group="items"
class="q-pa-md row items-start q-gutter-md"
direction="horizontal"
item-key="name"
#start="drag = true"
#end="drag = false"
>
<template #item="{ element }">
<q-card class="card">
<q-img src="~assets/temp/bb-auto.png" :alt="`Image ${element.name}`">
<div class="absolute-bottom text-subtitle2 text-center">
Image {{ element.name }}
</div>
</q-img>
</q-card>
</template>
</draggable>
</template>
<script setup lang="ts">
import { ref } from 'vue';
import draggable from 'vuedraggable';
const drag = ref(false);
const items = ref([
{ name: 'item1' },
{ name: 'item2' },
{ name: 'item3' },
{ name: 'item4' },
{ name: 'item5' },
]);
</script>
<style scoped>
.card {
width: 100%;
max-height: 200px;
max-width: 200px;
display: flex;
}

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'completed') in Vue 3

I'm trying to create Todo List App with Laravel and Vue.js.
I have problem with that title error.
I've watched this video (https://www.youtube.com/watch?v=UHSipe7pSac&t=2482s) for paractcing
And also, I've done until 47:50, but when I wrote a a code listItem.vue, It didn't work as shown in video.
Although I compared with mycode for many times, I couldn't where is wrong.
If you have solution, Please tell me how to fix.
And, What is best way how to debug apps with laravel and Vue.js?
Here is my version

I learned and understood listItem.vue's parent is listView.vue.
What a silly mistake I had made!

sorry to take up your time.

Vue testing with Vuetify. Cannot read property 'title' of undefined

I am trying to test if the dialog created with vuetify will be active or not after I emit a function called closeNoteForm. However, when I try to test the dialog content being hidden or not, I get an error. It seems the problem is within the noteForm wrapper that I created. But it just points to the css and doesn't make much sense to me.
In my NoteForm component
<template>

I don't understand why its pointing to my scss and saying undefined?
You don't add props to your wrapper in tests.
Add this code to your test.
const noteWrapper = mount(Note, {
localVue,
vuetify,
propsData: {
note: {
title: '',
}
});

Getting different

I have a problem related to Vue.js probs (I guess). I have a chart which fetches data in the created() from an API which looks like this:
<template>
<div>
<highcharts if="data.length > 0" :options="chartOptions" ></highcharts>
</div>
</template>
<script>
import { Chart } from "highcharts-vue";
import Highcharts from "highcharts";
import exportingInit from "highcharts/modules/exporting";
exportingInit(Highcharts);
export default {
props: {
partsdata: {
type: Array
}
},
created() {
this.$http.get('http://127.0.0.1:5000/data/')
.then(response => {
var result = JSON.parse(response.data)
return result
}).then(data => {
var result = data.Fare
console.log(result) // eslint-disable-line no-console
this.chartOptions.series[0].data = [] // Array wieder zurücksetzen
for(var key in result) {
this.chartOptions.series[0].data.push(result[key]) // eslint-disable-line no-console
}
})
},
components: {
highcharts: Chart
},
data() {
return {
data: [],
chartOptions: {
title: {
text: 'Title aligned left',
align: 'left',
x: 0
},
series: [{
type: "column",
data: [] // sample data
}]
}
}
}
};
</script>
<style scoped>
.btn-primary {
padding: 10px 20px;
background: white;
color: black;
margin-top: 15px;
margin-bottom: 15px;
border-radius: 5px;
}
</style>
This is my parent component, where I use my Charts, which works fine.
<template>
<v-container grid-list-md text-xs-center>
<v-layout row wrap>
<v-flex xs6>
<v-card dark color="white">
<v-card-text class="px-0">
<Highcharts></Highcharts>
</v-card-text>
</v-card>
</v-flex>
<v-flex xs6>
<v-card dark color="white">
<v-card-text class="px-0">
<Highcharts></Highcharts>
</v-card-text>
</v-card>
</v-flex>
<v-flex xs6>
<v-card dark color="white">
<v-card-text class="px-0">
<Highcharts></Highcharts>
</v-card-text>
</v-card>
</v-flex>
<v-flex xs6>
<v-card dark color="white">
<v-card-text class="px-0">
<Highcharts></Highcharts>
</v-card-text>
</v-card>
</v-flex>
</v-layout>
</v-container>
</template>
<script>
import Highcharts from "./Header.vue"
export default {
components: {
Highcharts: Highcharts
}
}
</script>
<style scoped>
</style>
However, what I want is to fetch the data from different Endpoints without creating a ton of new components. Is there a way to use the created() lifecycle hook as props or are there any other clever solutions how to archieve this?

Use method in template, out of instance vue

This is warning when i click on go to contact in tab about: "Property or method "switchTo" is not defined on the instance but referenced during render. Make sure to declare reactive data properties in the data option.
(found in component )."
How do I fix this?
new Vue({
el: '#app',
data: {
currentPage: 'home',
},
methods: {
switchTo: function(page) {
this.currentPage = page;
}
},
components: {
home: {
template: `#home`,
},
about: {
template: `#about`,
},
contact: {
template: '#contact'
}
}
})
.navigation {
margin: 10px 0;
}
.navigation ul {
margin: 0;
padding: 0;
}
.navigation ul li {
display: inline-block;
margin-right: 20px;
}
input, label, button {
display: block
}
input, textarea {
margin-bottom: 10px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.1.10/vue.js"></script>
<div id="app">
<div class="navigation">
<ul>
<li>Home</li>
<li>About</li>
</ul>
</div>
<div class="pages">
<keep-alive>
<component v-bind:is="currentPage">
</component>
</keep-alive>
</div>
</div>
<template id="home">
<p>home</p>
</template>
<template id="about">
<p>about go to contact</p>
</template>
<template id="contact">
<p>contact</p>
</template>
Just change your about template to this
<template id="about">
<p>about go to contact</p>
</template>
new Vue({
el: '#app',
data: {
currentPage: 'home',
},
methods: {
switchTo: function(page) {
this.currentPage = page;
}
},
components: {
home: {
template: `#home`,
},
about: {
template: `#about`,
},
contact: {
template: '#contact'
}
}
})
.navigation {
margin: 10px 0;
}
.navigation ul {
margin: 0;
padding: 0;
}
.navigation ul li {
display: inline-block;
margin-right: 20px;
}
input, label, button {
display: block
}
input, textarea {
margin-bottom: 10px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.1.10/vue.js"></script>
<div id="app">
<div class="navigation">
<ul>
<li>Home</li>
<li>About</li>
</ul>
</div>
<div class="pages">
<keep-alive>
<component v-bind:is="currentPage">
</component>
</keep-alive>
</div>
</div>
<template id="home">
<p>home</p>
</template>
<template id="about">
<p>about go to contact</p>
</template>
<template id="contact">
<p>contact</p>
</template>
I already solved a problem like this in this question: Calling methods in Vue build
It's not the same problem so it's not a repeated question, but the answer is the same:
In the created hook, add the component to window.componentInstance like this:
methods: {
foo () {
console.log('bar')
}
},
created () {
window.componentInstance = this
}
Then you can call the method anywhere like this:
window.componentInstance.foo()
