Vue 2 Imported Component Property or Method not defined - laravel

I'm attempting to nest some components - ultimately I would like to have a component which displays Posts, with a PostItem component used to render each post. Inside the PostItem, I want a list of related comments, with CommentItem to render each comment. I have the posts displayed using the PostItem with no errors, but as soon as I add the Comments I get errors. So to simplify, I've pulled the CommentsList component out and I'm just trying to display it on the page, manually loading in all comments - it's an exact copy of PostsList, except with comment replacing post, but it generates an error:
[Vue warn]: Property or method "commment" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property. See: https://v2.vuejs.org/v2/guide/reactivity.html#Declaring-Reactive-Properties.

I'm pretty new to Vue - I've read so many tutorials and have been digging through the documentation and can't seem to figure out why its working for me with my PostsList component thats an exact copy. It also seems odd that I need both comment and comments in the data return - something that my working Posts version requires.
I'll drop in my working Posts components:

How get quill and other form to JS submit function?

I wanna use quill rich editor and other fields on my form. But cant get access to quill innerHTML from JS function. I am using Laravel with Alpinejs and my code is
<form x-data="contactForm()" #submit.prevent="submit">
<div class="col-12">
<div class="mt-2 w-100 bg-white" wire:ignore>
<div
x-data
x-ref="quillEditor"
x-init="
quill = new Quill($refs.quillEditor, {
theme: 'snow',
modules: {toolbar: '#toolbar'}
});
quill.on('text-change', function () {
$dispatch('input', quill.root.innerHTML);
});"
wire:model.debounce.2000ms="description"
class="sign__textarea"
style="height: 300px;"
>{{ old('description', $services_users->description) }}
</div>
</div>
</div>
<div class="col-12">
<input name="message" x-model="data.title">
</div>
<div class="col-12 col-xl-3 mt-5">
<button type="submit" x-text="buttonText" :disabled="loading"></button>
</div>
</form>
<script>
function contactForm() {
return {
data: {
title: "",
myQuill: quill.root.innerHTML,
},
buttonText: "Save",
loading: false,
submit() {
this.buttonText = "Saving...";
this.loading = true;
fetch('myurl.endpoint', {
method: "POST",
headers: {
"Content-Type": "application/json",
"Accept": "application/json",
},
body: JSON.stringify(this.data),
}).then(() => {
alert("Form submitted");
}).catch(() => {
alert("Something went wrong");
}).finally(() => {
this.data.title = ""
this.buttonText = "Save";
this.loading = false;
});
},
};
}
</scirpt>
Now i have an error Can't find variable: quill how can i get all fields from form and send to backend event if quill is not a form field?
It doesn't work because you're calling the variable "quill" in the parent and you're declaring it in the child. To fix it declare the x-init directive in the form.
listening to the "text-change" event is not necessary. A good option is to add the content of the container before submitting the form.
see : https://alpinejs.dev/directives/data#scope
<form x-data="contactForm()" x-init="
quill = new Quill($refs.quillEditor, {
theme: 'snow'
});
quill.on('text-change', function () {
$dispatch('input', quill.root.innerHTML);
});" #submit.prevent="submit">
<div class="col-12">
<div class="mt-2 w-100 bg-white" wire:ignore>
<div
x-ref="quillEditor"
wire:model.debounce.2000ms="description"
class="sign__textarea"
style="height: 300px;"
>{{ old('description', $services_users->description) }}
</div>
</div>
</div>
<div class="col-12">
<input name="message" x-model="data.title">
</div>
<div class="col-12 col-xl-3 mt-5">
<button type="submit" x-text="buttonText" :disabled="loading"></button>
</div>
</form>
<script>
function contactForm() {
return {
quill:null,
data: {
title: "",
// myQuill: function(){ return this.quill.root.innerHTML}
},
buttonText: "Save",
loading: false,
submit() {
this.buttonText = "Saving...";
//add content quill here
this.data.myQuill = this.quill.root.innerHTML;
this.loading = true;
fetch('myurl.endpoint', {
method: "POST",
headers: {
"Content-Type": "application/json",
"Accept": "application/json",
},
body: JSON.stringify(this.data),
}).then(() => {
alert("Form submitted");
}).catch(() => {
alert("Something went wrong");
}).finally(() => {
this.data.title = ""
this.buttonText = "Save";
this.loading = false;
});
},
};
}
</script>
Ok this is what i did
<form x-data="contactForm()" x-init="initQuill()" x-on:submit="submit()" method="POST" action="target.url">
<div x-ref="editor"></div>
<input x-ref="editorValue" type="hidden" name="hidden_input">
<button>Save</button>
</form>
<script>
function contactForm(){
return {
initQuill(){
new Quill(this.$refs. editor, {theme: 'snow'});
},
submit(){
console.log(this.$refs. editor.__quill.root.innerHTML);
this.$refs.editorValue.value = this.$refs.editor.__quill.root.innerHTML;
}
}
}
</script>
Now is ok and works with basic. You can extend function with new features etc. Thx for help guys.

Post request by axios (VueJS) in laravel giving 500 error

I am trying to make a post request via axios but getting this error: app.js:285 POST http://127.0.0.1:8000/concerts/1/orders 500 (Internal Server Error)
The order is being processed though (I see it coming is Stripe and database). Another problem is that redirect is not happening as window.location =/orders/${response.data.confirmation_number}; I just stay on the same page.
Any ideas what could go wrong here?

computed: {
description() {
if (this.quantity > 1) {
return `${this.quantity} tickets to ${this.concertTitle}`
}
return `One ticket to ${this.concertTitle}`
},

return this.quantity * this.price
},

return (this.price / 100).toFixed(2)
},

return (this.totalPrice / 100).toFixed(2)
},
},

initStripe() {
const handler = StripeCheckout.configure({

})
window.addEventListener('popstate', () => {
handler.close()
})
return handler
},
openStripe(callback) {
this.stripeHandler.open({
name: 'TicketBeast',
description: this.description,
currency: "usd",
allowRememberMe: false,
panelLabel: 'Pay {{amount}}',
amount: this.totalPrice,
// image: '/img/checkout-icon.png',
token: this.purchaseTickets,
})
},
purchaseTickets(token) {
this.processing = true
axios.post(`/concerts/${this.concertId}/orders`, {
email: token.email,
ticket_quantity: this.quantity,
payment_token: token.id,
}).then(response => {
window.location =`/orders/${response.data.confirmation_number}`;
console.log('Charge succeeded.')
}).catch(response => {
this.processing = false
})
}
},
created() {
this.stripeHandler = this.initStripe()
}
}
You have to go and look under the Network tab if you are using Chrome browser, you can see the failed request response
The issue turns out to be Mailer. In .env file, along with Mailtrap credentials you must provide sender email and they don't tell you that :( This also somehow prevented the redirect. In case that helps someone.

fetch() function is not working in methods

I am trying to retrieve data from REST API. I got below code from a tutorial which are not working in my machine but working in that video.
<template>
<div>
<h2>Articles</h2>
<div class="card mb-2" v-for="article in articles" v-bind:key="article.id">
<div class="card-header">
{{ article.title }}
</div>
<div class="card-body">
{{ article.body }}
</div>
</div>
</div>
</template>
<script>
export default {
data(){
return {
articles : [],
article : {
id : '',
title : '',
body : ''
},
article_id : '',
pagination : {},
edit : false
}
},
created(){
this.fetchArticles();
},
methods:{
fetchArticles(){
fetch('api/articles')
.then(res => res.json())
.then(res => {
this.arcticles = res.data;
console.log(res.data);
})
}
}
}
</script>
After few research I changed my code to
<template>
<div>
<h2>Articles</h2>
<div class="card mb-2" v-for="article in articles" v-bind:key="article.id">
<div class="card-header">
{{ article.title }}
</div>
<div class="card-body">
{{ article.body }}
</div>
</div>
</div>
</template>
<script>
export default {
data(){
return {
articles : [],
article : {
id : '',
title : '',
body : ''
},
article_id : '',
pagination : {},
edit : false
}
},
created(){
axios
.get('api/articles')
.then(res => {
this.articles = res.data.data;
console.log(res.data.data);
})
},
}
</script>
and it's working fine.
I want to fix the previous code (from the tutorial). Otherwise I'll not get further lessons.
From MDN documentation, the json() method is implemented on Response body, and it returns a promise wich resolves to result of parsing the body text as json.
response.json().then(data => {
// do something with your data
});
So, when using in fetch, the correct syntax is:
fetchArticles(){
fetch('api/articles')
.then(res => res.json())
.then(data=> {
this.arcticles = data; // the result here contains only the json data, it is not a response object, so it does not have a 'data' property.
console.log(data);
})
}

Search functionality with rest api prevent DDOSing the server

The Problem
I have a search component and component which implements the search component. When I type something in the search bar after 1/2 second of not typing (debounce) the server should be hit and the results should be returned.
The solution i am trying to implement comes from this post on Stackoverflow
The code
This leads me to the following code.
I have search.vue
<template>
<label for="search">
<input
id="search"
class="w-full py-2 px-1 border-gray-900 border"
type="text"
name=":searchTitle"
v-model="searchFilter"
:placeholder="searchPlaceholder"
autocomplete="off"
v-on:keydown="filteredDataset"
/>
</label>
</template>
<script>
import {debounce} from 'lodash';
export default {
props: {
searchPlaceholder: {
type: String,
required: false,
default: ''
},
searchName: {
type: String,
required: false,
default: 'search'
}
},
data() {
return {
searchFilter: '',
}
},
methods: {
filteredDataset() {
console.log('event fired');
this.$emit('searchValue', this.searchFilter);
}
},
}
</script>
And product.vue
<template>
<div>
<div class="my-4">
<search
search-placeholder=""
search-name=""
v-on:searchValue="filterValue = $event"
v-model="productsFiltered"
>
</search>
<div class="flex w-full py-1 border px-2 my-2" v-for="product in productsFiltered"> (...)
</div>
</div>
</div>
</div>
</template>
<script>
import {debounce} from 'lodash';
export default {
data() {
return {
products: [],
filterValue: '',
filteredProducts: ''
}
},
computed: {
productsFiltered: {
get(){
console.log('getter called');
return this.filteredProducts;
},
set: _.debounce(function(){
console.log('setter called');
if (this.filterValue.length < 1) {
this.filteredProducts = [];
}
axios.get(`${apiUrl}search/` + this.filterValue)
.then(response => {
this.products = response.data.products;
const filtered = [];
const regOption = new RegExp(this.filterValue, 'ig');
for (const product of this.products) {
if (this.filterValue.length < 1 || product.productname.match(regOption)) {
filtered.push(product);
}
}
this.filteredProducts = filtered;
});
}, 500)
}
},
}
</script>
The result
The result is that the setter in the computed property in product.vue does not get called and no data is fetched from the server. Any ideas on how to solve this?
Your first code block imports debounce but does not use it. It also declares a prop, searchName, that isn't used. These aren't central issues, but clutter makes it harder to figure out what's going on.
Your second code block uses v-model but does not follow the required conventions for getting v-model to work with components:
the component must take a prop named value
the component must emit input events to signal changes to value
You have the component emit searchValue events, and handle them with a v-on that sets a data item. You seem to expect the v-model to call the setter, but as I noted, you haven't hooked it up to do so.
From what's here, you don't even really need to store the input value. You just want to emit it when it changes. Here's a demo:
const searchComponent = {
template: '#search-template',
props: {
searchPlaceholder: {
type: String,
required: false,
default: ''
}
},
methods: {
filteredDataset(searchFilter) {
console.log('event fired');
this.$emit('input', searchFilter);
}
}
};
new Vue({
el: '#app',
data() {
return {
products: [],
filterValue: '',
filteredProducts: ''
}
},
components: {
searchComponent
},
computed: {
productsFiltered: {
get() {
console.log('getter called');
return this.filteredProducts;
},
set: _.debounce(function() {
console.log('setter called');
if (this.filterValue.length < 1) {
this.filteredProducts = [];
}
setTimeout(() => {
console.log("This is the axios call");
this.filteredProducts = ['one','two','three'];
}, 200);
}, 500)
}
}
});

Passing parameter from axios to laravel

In my application I'm working with comment, each product has its own comment.Comment in MySql contains column 'computer_comment' with foreign key(id).When I send 'computer_comment' from axios to laravel comments doesn't shown, I guess that 'computer_comment' is null or undefined.
I tried to send 1 or 2 instead 'computer_comment', in this case it works.
CommentComponent.vue
<template>
<div>
<div v-for="l in list">
<div v-if="l.computer_comment==current">
<div class="card" >
<div class="card body" >
<h4 style="text-decoration: underline">{{l.name}}</h4>
<p >{{l.body}}</p>
</div>
</div>
<br>
</div>
</div>
</div>
</template>
<script>
export default{
props: ['message'],
data(){
return{
list: [],
comment:{
id: '',
user_comment: '',
computer_comment: '',
name: '',
body: ''
},
current: this.message
}
},
created() {
this.show_comment();
},
methods: {
show_comment(){
axios.get('/current_comment').then(result => {
this.list = result.data;
console.log(result.data);
});
},
removeCom(id){
axios.post('/remove/'+id).then(result => {
this.show_comment();
}).catch(err => {
console.log(err);
});
}
},
}
</script>
info.blade.php
<div id="info">
<comment message="{{$computer->id}}"></comment>
.....
</div>
