I have 3 components like: Parent, First-child and Second-child. And I am iterating First-child in Parent component in array(it is cards), and I want to call Second-child in Parent component with First-child's props(props of one card).
My Parent component looks like this(how I am calling First-child):
``
<CardComponent
v-for="card of cards"
:key="card.urlsId"
:cardImages="card.images"
:cardTitle="card.title"
:cardDescription="card.description"
:mediaRef="card.urlsId"
:dbRef="card.dbId"
:deleteBtn="true"
:imagesWithSlider="true"
/>
And my First child is:
<template>
<div class="cards">
<v-card class="card-container">
<div class="delete-btn">
<v-btn
v-if="deleteBtn"
class="mx-2"
fab
dark
small
#click="$emit('onOpenDeleteModal')"
>
<v-icon dark> mdi-delete </v-icon>
</v-btn>
</div>
<ImageSlider
v-if="imagesWithSlider"
:imagesArray="cardImages"
:arrowBtns="false"
/>
<div class="text-container">
<h3 class="card-title">{{ cardTitle }}</h3>
<p class="card-description">{{ cardDescription }}</p>

</v-card>
</div>
</template>
<script>
export default {

},
emits: ['onOpenDeleteModal', 'onCloseDeleteModal'],
}
</script>
And my Second-child is:
<template>
<v-card class="modal" :loading="newCard.loading ? true : false">
<v-card class="modal-header">

async getMediaUrlsFromStorage(newCardData) {
const cardMediaRef = uuidV1()
const cardImagesRef = await this.$fire.storage
.ref('/albums_cards/')
.child(cardMediaRef)
const videoRef = await cardImagesRef.child(uuidV4())
if (this.newCard.cardVideo) {
await videoRef.put(this.newCard.cardVideo)
const videoUrl = await videoRef.getDownloadURL()
newCardData.video = videoUrl
}
newCardData.urlsId = cardMediaRef
const promiseArr = this.newCard.cardImages.map(async (image) => {
const imageRef = cardImagesRef.child(uuidV4())
await imageRef.put(image)
const imageUrl = await imageRef.getDownloadURL()
newCardData.images.push(imageUrl)
})
await Promise.all(promiseArr)
},
async postNewCardToDb() {
this.newCard.loading = true
const newCardData = {
urlsId: '',
title: this.newCard.cardTitle,
description: this.newCard.cardSnippet,
video: '',
images: [],
}
await this.getMediaUrlsFromStorage(newCardData)
await this.$fire.database.ref('albums/cards').push(newCardData)
console.log(newCardData)
this.newCard.loading = false
this.newCard.cardTitle = null
this.newCard.cardSnippet = null
this.newCard.cardImages = []
this.newCard.cardImageUrls = []
this.newCard.cardVideo = null
},
},
}
</script>
First-child is a card component and I need to pass props of each card to Second-child without calling it. I cant call Second-child in First-child because of iteration.
I hope I expleined it well

I want to test my custom component via vue-test-utils. I use vuetify autocomplete component in this case. I just wrapped with div and extract as a custom component. Nothing to do special so far.
This component is really works on development. I have no problem with it.
I used this component as shown below.
<my-component
id="brand-dropdown"
ref="brand-dropdown"
:items="brands"
labelKey="product.brand"
item-text="name"
item-value="name"
v-model="product.brandName"/>
My custom component looks like:
<template>
<div class="comboContainer">
<v-autocomplete
class="product-combobox"
ref="complete"
:items="localItems"
append-icon="$dropdownArrow"
outlined
dense
hide-details
color="#999999"
:item-text="itemText"
:item-value="itemValue"
:filter="autoCompleteFilter"
v-model="selected"
#change="onListItemSelected">
<template slot="label">
<span>{{$t(labelKey)}}</span>
</template>
<template slot="prepend-inner" v-if="showSearchIcon">
<div class="d-flex align-center justify-center"
style="height: 25px;">
<img src="~/assets/icons/search/search.png"/>
</div>
</template>
<template v-slot:no-data>
<v-list-item id="noMatchText">
<v-list-item-title>
<div :no-data-item="dataTestId">
{{ $t('selection.noMatchFound') }}
</div>
</v-list-item-title>
</v-list-item>
</template>

</template>
<div class="popup-rectangle">

<script>
export default {

}
return [];
},
},
methods: {
onListItemSelected() {
this.$emit('input', this.selected);
},
autoCompleteFilter(item, queryText, itemText) {
const re = new RegExp(`(\\s+|^)(${queryText.toLocaleLowerCase()})(.*|$)`);
return re.test(itemText.toLocaleLowerCase());
},
},
};
I want to test three test case.
When I pass empty list should render as empty dropdown and render no-data slot.
<template v-slot:no-data>
<v-list-item id="noMatchText">
<v-list-item-title>
<div :no-data-item="dataTestId">
{{ $t('selection.noMatchFound') }}
</div>
</v-list-item-title>
</v-list-item>
</template>
When I pass filled list with test data I want to test all items rendered correctly
<template v-slot:item="{ item }">
<v-tooltip top color="transparent">
<template v-slot:activator="{ on, attrs }">
<div
v-on="item[itemText].length >36?on:null"
class="combobox-item comboboxOverFlow"
:data-testid="itemDataTestIdPrefix+item.id"
:parent-list="dataTestId">
<span>{{ item[itemText] }}</span>
</div>
</template>
<div class="popup-rectangle">
<span>{{ item[itemText] }}</span>
</div>
</v-tooltip>
</template>
When I search I want to provide my filter function works as expected. And autocomplete renders items according to filtered value.
This is what my test file.
function mountComponent(options) {
return mount(ComboBox, {
vuetify: new Vuetify(),
sync: false,
mocks: {
$t: key => key,
$i18n: { locale: 'en' },
},
...options,
});
}
describe('Combobox unit tests', () => {
beforeEach(() => {
document.body.setAttribute('data-app', 'true');
});
test('should create component successfully', () => {
const wrapper = mountComponent({ items: [] });
expect(wrapper.exists()).toBeTruthy();
});
test('should list zero items if the item list is empty', async () => {
const wrapper = mountComponent({
propsData: {
items: [],
labelKey: 'labelKey',
dataTestId: 'test-dropdown',
itemText: 'name',
itemValue: 'id',
},
});
const autocomplete = wrapper.find('.product-combobox');
const autocompleteControls = autocomplete.find('.v-input__slot');
autocompleteControls.trigger('click');
await wrapper.vm.$nextTick();
await flushPromises();
**// v menu cant opened !!!!**
});
test('should list third items correctly', async () => {
const testItems = [{ name: 'item1', id: 1 }, { name: 'item2', id: 2 }, { name: 'item3', id: 3 }];
const wrapper = mountComponent({
attachToDocument: true,
propsData: {
eagerProp: true,
items: testItems,
dataTestId: 'test-dropdown',
itemDataTestIdPrefix: 'test-dropdown-item-',
itemText: 'name',
itemValue: 'id',
value: null,
},
});
const slot = wrapper.find('.v-input__slot');
const input = wrapper.find('input');
// Focus input should only focus
input.trigger('focus');
expect(wrapper.vm.$children[0].isFocused).toBe(true);
expect(wrapper.vm.$children[0].menuCanShow).toBe(true);
expect(wrapper.vm.$children[0].isMenuActive).toBe(false);
slot.trigger('click');
expect(wrapper.vm.$children[0].isMenuActive).toBe(true);
expect(wrapper.vm.$children[0].menuCanShow).toBe(true);
wrapper.setProps({ searchInput: 'foo' });
expect(wrapper.vm.$children[0].isMenuActive).toBe(true);
expect(wrapper.vm.$children[0].menuCanShow).toBe(true);
// v menu cant opened !!!!
// you think these expects is unnecesary. you are right I just explore this component
// if I success I'll delete all of them
});
test('should filter autocomplete search results', async () => {
});
});
I can't open v-menu in test enviroment.
I tried emit events and trigger('click')
When I console log wrapper.html() I cant see v menu is opened and all items rendered in html. Output is shown below.
<div class="comboContainer">
<div class="v-input product-combobox v-input--hide-details v-input--dense theme--light v-text-field v-text-field--enclosed v-text-field--outlined v-select v-autocomplete">
<div class="v-input__control">
<div role="combobox" aria-haspopup="listbox" aria-expanded="false" aria-owns="list-2" class="v-input__slot" style="height: 44px;">
<fieldset aria-hidden="true">
<legend style="width: 0px;"><span></span></legend>
</fieldset>
<div class="v-select__slot">
<label for="input-2" class="v-label theme--light" style="left: 0px; position: absolute;"><span></span></label><input data-testid="test-dropdown" id="input-2" type="text" autocomplete="off">
<div class="v-input__append-inner">
<div class="v-input__icon v-input__icon--append"><i aria-hidden="true" class="v-icon notranslate material-icons theme--light">$dropdownArrow</i></div>
</div>
<input type="hidden">
</div>
<div class="v-menu"></div>
</div>
</div>
</div>
</div>
My problem is where is items? <div class="v-menu"></div> Why I cant see in wrapper.html. I don't use shallowMount, I use mount. Because of this I cannot write my covered test cases.
How can I simulate opened menu and rendered all items and provide some assertions?
What am I missing?

Well, probably the better way would be mocking and substituting v-autocomplete with a test component (just control values that go to it and emit fake events from it). You are not developing Vuetify, so no need to test what happens inside a component.
I am developing a recipe app. At my CreateRecipe component, I have child component to add ingredients to the recipe or edit existing ingredients. Ill start by showing the code and what i want to achieve and then the problem
Parent component:
<template>

this.editedIndex = this.article.igredients.indexOf(item);
this.editedIgredient = Object.assign({}, item);
this.AddIgredientsDialog = true;
},
SaveNewIgredient(newItem) { //Triggered on #click of save button at child component New item is the
//item passed from children
if (this.editedIndex > -1) {
this.editedIgredient = Object.assign({}, newItem);
Object.assign(
this.article.igredients[this.editedIndex],
this.editedIgredient
);
} else {
this.article.igredients.push(this.editedIgredient);
}
this.AddIgredientsDialog = false;
this.$nextTick(() => {

}
}
},
data: () => ({
newIgredient: ""
}),
methods: {
addNewIgredient() {
this.newIngredientsItem.subIgredients.push(this.newIgredient);
this.newIgredient = "";
},
AddIngredients() {
this.$emit("addIngredient", this.newIngredientsItem);
},
removeIgredient(index) {
this.newIngredientsItem.subIgredients.splice(index, 1);
}
}
};
</script>
My Problem:
At the moment im only trying to use the SaveNewIgredient() method.
After 1st time of adding item the item is added as it should and the parent defaultItem state remain as is which is good:
defaultItem: {
title: "",
subIgredients: []
},
After adding a second item the defaultItem changes and takes the editedItem properties.
For example if i add at the second time
{
title:'Test 1',
subIgredients: [
'Test 1 - 1',
'Test 1 - 2',
'Test 1 - 3',
]
}
That is what the defaultItem will be and then this assignment causes a bug
this.editedIgredient = Object.assign({}, this.defaultItem);
because editedItem should be:
{
title: "",
subIgredients: []
}
I tried to solve your problem. To do this I modified and in some places simplified your code to keep only what was close to the SaveNewIgredient() function. So here is my code.
Parent Component (for me App.vue):
<template>
<AddItemsForm #addIngredient="SaveNewIgredient" />
</template>
<script>
import AddItemsForm from "./AddItemsForm"; //Child Component
export default {
name: "App",
components: { AddItemsForm },
data() {
return {
article: {
igredients: [], //List to add/edit item at AddItemsForm child component
},
editedIgredient: {
//Item to use for editing or adding new item to article.igredients
title: "",
subIgredients: [],
},
defaultItem: {
//Item used for resetting editedIgredient item
title: "",
subIgredients: [],
},
};
},
methods: {
SaveNewIgredient(newItem) {
console.log("Received: ", newItem);
this.editedIgredient = newItem;
this.article.igredients.push({ ...this.editedIgredient });
console.log("defaultClear: ", this.defaultItem);
console.log("infoItem: ", this.editedIgredient);
this.editedIgredient = this.defaultItem;
console.log("defaultClear: ", this.defaultItem);
console.log("editedWillClear: ", this.editedIgredient);
console.log("listFinal: ", this.article.igredients);
},
},
};
</script>
Child Component (for me AddItemsForm.vue):
<template>
<div>
<input v-model="newIgredient" placeholder="New Igredient" />
<button #click="addNewIgredient">ADD</button>
<div>
<button color="primary" #click="AddIngredients">Save</button>
</div>
</div>
</template>
<script>
export default {
props: {
IngredientsItem: {
type: Object,
default() {
return {
title: "",
subIgredients: [],
};
},
},
},
data() {
return {
newIgredient: "",
title: "TEST",
titleNbr: 0,
resetIgredient: false,
};
},
computed: {
newIngredientsItem() {
return this.IngredientsItem;
},
},
methods: {
addNewIgredient() {
if (this.resetIgredient === true) {
this.newIngredientsItem.subIgredients = [];
}
this.newIngredientsItem.subIgredients.push(this.newIgredient);
this.newIgredient = "";
this.resetIgredient = false;
console.log("ADD: ", this.newIngredientsItem.subIgredients);
},
AddIngredients() {
this.newIngredientsItem.title = this.title + this.titleNbr;
this.titleNbr++;
console.log("EMIT: ", this.newIngredientsItem);
this.$emit("addIngredient", this.newIngredientsItem);
this.resetIgredient = true;
},
},
};
</script>
i used snackbar to show success messages in vuejs. i want to make a global custom snackbar component.
<template>
<div name="snackbars">
<v-snackbar
v-model="snackbar"
:color="color"
:timeout="timeout"
:top="'top'"
>
{{ text }}
<template v-slot:action="{ attrs }">
<v-btn dark text v-bind="attrs" #click="snackbar = false">
Close
</v-btn>
</template>
</v-snackbar>
</div>
</template>
<script>
export default {
props: {
snackbar: {
type: Boolean,
required: true,
},
color: {
type: String,
required: false,
default: "success",
},
timeout: {
type: Number,
required: false,
default: 3000,
},
text: {
type: String,
required: true,
},
},
};
</script>
then i import this as a component in my every form like this.
<SnackBar :snackbar="snackbar" :color="color" :text="text" />
but my issue is i can't use snackbar as a prop in my child component. it shows me this error.
Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop's value. Prop being mutated: "snackbar"
how can i fix this issue. can anyone help me?
I realize this is old, but thanks to google, I am going to add my solution.
I use this, because I don't see the point of using vuex for a snackbar. It's more work then needed.
Create a vue component named vtoast
<template>
<v-snackbar
:color="color"
:timeout="timer"
v-model="showSnackbar"
bottom
right
>
<v-icon left>{{icon}}</v-icon>{{message}}
</v-snackbar>
</template>
<script>
export default {
name: "vtoast",
data() {
return{
showSnackbar: false,
message: '',
color: 'success',
icon: 'mdi-check',
timer: 3000
}
},
methods:{
show(data) {
this.message = data.message || 'missing "message".'
this.color = data.color || 'success'
this.timer = data.timer || 3000
this.icon = data.icon || 'mdi-check'
this.showSnackbar = true
}
}
}
</script>
Somewhere in the root of your main app, add the following. (I usually put mine in App.vue)
<template>
...
<!-- toast -->
<vtoast ref="vtoast"/>
...
</template>
<script>
import vtoast from '#/your/vtoast/directory/vtoast'
export default{
name: 'App', //or whatever your root is
components:{
vtoast
},
mounted() {
this.$root.vtoast = this.$refs.vtoast
},
}
</script>
And access it like so...
this.$root.vtoast.show()
this.$root.vtoast.show({message: 'Ahoy there!'})
i found a way to fix my solution using vuex.
<template>
<div name="snackbars">
<v-snackbar v-model="show" :color="color" :timeout="timeout" :top="'top'">
{{ text }}
<template v-slot:action="{ attrs }">
<v-btn dark text v-bind="attrs" #click="show = false">
Close
</v-btn>
</template>
</v-snackbar>
</div>
</template>
<script>
export default {
created() {
this.$store.subscribe((mutation, state) => {
if (mutation.type === "snackbar/SHOW_MESSAGE") {
this.text = state.snackbar.text;
this.color = state.snackbar.color;
this.timeout = state.snackbar.timeout;
this.show = true;
}
});
},
data() {
return {
show: false,
color: "",
text: "",
timeout: 0,
};
},
};
</script>
in my vuex module i wrote like this
export default {
namespaced: true,
state: {
text: "",
color: "",
timeout: "",
},
mutations: {
SHOW_MESSAGE(state, payload) {
state.text = payload.text;
state.color = payload.color;
state.timeout = payload.timeout;
},
},
actions: {
showSnack({ commit }, payload) {
commit("SHOW_MESSAGE", payload);
},
},
};
then i import snackbar child component into my parent component and send data like this.
...mapActions("snackbar", ["showSnack"]),
saveDetails() {
this.showSnack({
text: "Successfully Saved!",
color: "success",
timeout: 3500,
});
}
Another solution is to use a computed value with getter and setter.
Using options api
<template>
<v-snackbar v-model="show" :color="color">
{{ message }}
<template v-slot:action="{ attrs }">
<v-btn text v-bind="attrs" #click="show = false">Close</v-btn>
</template>
</v-snackbar>
</template>
<script>
import { mapGetters } from 'vuex';
export default {
computed: {
...mapGetters({
message: 'snackbar/message',
color: 'snackbar/color'
}),
show: {
get() {
return this.$store.state.snackbar.show
},
set(v) {
this.$store.commit('snackbar/SET_SHOW', v)
}
}
}
}
</script>
Using composition api plugin
<template>
<v-snackbar v-model="show" :color="color">
{{ message }}
<template v-slot:action="{ attrs }">
<v-btn text v-bind="attrs" #click="show = false">Close</v-btn>
</template>
</v-snackbar>
</template>
<script>
import { defineComponent, computed } from '#vue/composition-api';
export default defineComponent({
setup(_props, { root }) {
const show = computed({
get: () => root.$store.state.snackbar.show,
set: (v) => root.$store.commit('snackbar/SET_SHOW', v),
});
const message = computed(() => root.$store.state.snackbar.message);
const color = computed(() => root.$store.state.snackbar.color);
return {
show,
message,
color,
};
},
});
</script>
A better implementation using composables here https://gist.github.com/wobsoriano/2f3f0480f24298e150be0c13f93bac20
You are having a prop and the same in data.
remove snackbar from data() as it is available from prop.
<script>
export default {
props: {
snackbar: {
type: Boolean,
required: true,
},
color: {
type: String,
required: false,
default: "success",
},
timeout: {
type: Number,
required: false,
default: 3000,
},
text: {
type: String,
required: true,
},
}
};
</script>
This is what I did with Options API with mere props and events;
Here is the Snackbar.vue component
<template>
<div class="text-center">
<v-snackbar
transition="true"
bottom
right
v-model="show"
:color="snackbar.color"
:timeout="snackbar.timeout"
class="snackbar-shadow"
>
<div class="d-flex align-start alert-notify">
<v-icon size="24" class="text-white mr-5">{{ snackbar.icon }}</v-icon>
<p class="mb-0">
<span class="font-size-root font-weight-600">{{
snackbar.title
}}</span>
<br />
{{ snackbar.message }}
</p>
</div>
<template v-slot:action="{ attrs }">
<v-btn
icon
elevation="0"
max-width="136"
:ripple="false"
height="43"
class="font-weight-600 text-capitalize py-3 px-6 rounded-sm"
color="rgba(255,255,255, .85)"
text
v-bind="attrs"
#click="show = false"
>
<v-icon size="13">fas fa-times</v-icon>
</v-btn>
</template>
</v-snackbar>
</div>
</template>
<script>
export default {
name: "snackbar",
props: {
snackbar: Object,
},
computed: {
show: {
get() {
return this.snackbar.visible;
},
set(value) {
this.$emit("closeSnackbar", value);
},
},
},
};
</script>
Here is the App.vue component
<template>
<!-- Snackbar -->
<snackbar :snackbar="snackbar" #closeSnackbar="SnackbarClose"></snackbar>
</template>
<script>
export default {
name: "app",
data() {
return {
snackbar: {
visible: false,
timeout: 2000,
color: "#11cdef",
title: "Hello",
message: null,
icon: "fas fa-bell",
},
};
},
created: { this.SnackbarShow(); }
methods: {
SnackbarShow() {
this.snackbar.visible = true;
this.snackbar.message = "Hola!👋 I'm a snackbar";
},
SnackbarClose() {
this.snackbar.visible = false;
},
},
};
</script>
I am trying to re-use the same component, but load the components with different data. I thought simply providing unique id's would do the trick, but no luck. I switched from a Vuex store for this data, to using a dataShare This is what I'm doing:
The components:
<logoHeader :panel=0 title="Add your logo / header" id="top" topPadding="pt-10" />
<logoHeader :panel=1 title="Add your main image" id="main" topPadding="pt-0"/>
So its the exact same component, with some different props and different ids
This is the logoHeader component:
<template>
<v-row
:class="topPadding"
align="center"
justify="center"
>
<v-col
align="center"
justify="center"
cols="12"
>
<v-hover v-slot:default="{ hover }">
<v-card
:elevation="hover ? 12 : 0"
class="mx-auto"
max-width="600"
>
<v-img
v-if="showImage"
:src="imageUrl"
max-width="600px"
class="pointer"
#click="panel = 0"
>
</v-img>
<v-icon
v-if="!showImage"
class="my_dark_purple_text"
size="100"
#click="sendToPanel"
>add_box</v-icon>
<p class="my_dark_purple_text">{{ title }}</p>
<p>URL {{ imageUrl }}</p>
<p>Show image? {{ showImage }}</p>
</v-card>
</v-hover>
</v-col>
</v-row>
</template>
<script>
import {mapGetters} from 'vuex';
import {mapActions} from 'vuex';
import {dataShare} from '../../../packs/fresh-credit.js';
export default {
props: ['panel', 'title', 'topPadding'],
data() {
return {
imageUrl: "",
showImage: false,
}
},
created() {
dataShare.$on('imageUrl', (data) => {
this.imageUrl = data;
});
dataShare.$on('showImage', (data) => {
this.showImage = data;
});
},
computed: {
...mapGetters('emailPanel', [
'returnPanel'
]),
},
methods: {
...mapActions('emailPanel', [
'updatePanel'
]),
sendToPanel() {
this.updatePanel(this.panel);
},
},
}
</script>
And then finally this is where the data enters the system:
<template>
<v-expansion-panel-content>
<h1 class="subtitle-1 font-weight-bold">Only images files accepted</h1>
<v-file-input
v-model="image"
accept="image/*"
label="Image Upload"
prepend-icon="add_a_photo"
color='#68007d'
></v-file-input>
<v-btn
:disabled="disableUpload"
color="#68007d"
class="white--text"
#click="sendImage"
>Submit</v-btn>
</v-expansion-panel-content>
</template>
<script>
import axios from 'axios';
import {dataShare} from '../../../../packs/fresh-credit.js';
export default {
data() {
return {
image: null,
disableUpload: true,
}
},
watch: {
image: function() {
if(this.image.size > 0){
this.disableUpload = false;
}
else{
this.disableUpload = true;
}
}
},
computed: {
},
methods: {
sendImage() {
let formData = new FormData();
formData.append('file', this.image);
axios.post('/admin/features/images', formData,
{
headers: {
'Content-Type': 'multipart/form-data'
}
}
).then(response => {
dataShare.$emit('imageUrl', response.data);
dataShare.$emit('showImage', true);
});
}
},
}
</script>
Where did I go astray?
Add the key property to the components and set it to different values (for example 1 and 2). If the key has different values Vue will differentiate them when rendering. Here is a basic explanation.
I'm using form validation in application, I want my validation error message to be translated. It is getting translated only after reset form.
I have tried translation in computed property, and it's working when I do
computed as below, but error message is not disappearing after touched:
{
return [this.$t('LANGUAGE')]
}
In App Component
<template>
<div id="app">
<grid_Component/>
<div class="locale-changer" style="background: black">
<select v-model="$i18n.locale">
<option v-for="(lang, i) in lang" :key="`Lang${i}`" :value="lang">{{
lang }}
</option>
</select>
</div>
</div>
</template>
<script>
import form_Component from './components/form_Component.vue'
import form_Component from './components/form_Component.vue'
import i18n from './i18n'
export default {
data () {
return{
lang: ['GB', 'NO']
}
},
name: 'app',
components: {
form_Component,
},
}
</script>
