I implemented the changes proposed in the comments. It is now working! Thanks a lot to everybody for your help
------------ Inital help request below : -------------------
I have a Home.vue parent component that I use as a home page. On this page I make a fetch request to have an array of posts. I try with a v-for to iterate through the array of posts and send each time a new post object.
My problem is the following:
- the array is send in full and thus only one Post template is generated...
Thank you in advanced for your time and I did some research, but without any success.
Find below the Home.vue parent component
<template>
<div >
<div v-for="(post, index) in posts" :key="index">
<ImageArticle
:articledata="post"
/>
</div>
</div>
</template>
<script>
import ImageArticle from "../components/imageArticle"
import { mapState } from "vuex"
export default {
name: 'Home',
components: {
ImageArticle,
},
data() {
return {
posts : [],
}
},
computed: {
...mapState({
UserName: "UserName",
UserLogin: "UserLogin",
UserEmail: "UserEmail",
UserPublications: "UserPublications",
UserFriends: "UserFriends"
})
},
created() {
this.getAllPosts()
},
methods:{
getAllPosts () {
var requestOptions = {
method: 'GET',
redirect: 'follow'
};
fetch("http://localhost:3000/api/post/", requestOptions)
.then(response => response.text())
.then((result) => {
this.posts = JSON.parse(result);
console.log(this.posts);
})
.catch(error => console.log('error', error));
}
}
}
</script>
Find below the child component, to which I try to send the post object, as a prop. (I deleted a lot of the code, to make it more readable)
<template>
<div>
<article >
<h4 >Kaerbran {{articleData.Post_Comment}}</h4>
</article>
</div>
</template>
<script>
import ModalBoxActionArticle from '../components/modalBoxActionArticle'
export default {
name: 'ImageArticle',
props : ['articledata'],
data() {
return {
articleData : this.articledata,
}
}
}
</script>
Find below the array I'm sending. I want to create a new template for each Post_ID.

CodePudding user response：
Few things to note:
First, the way you pass a key for the iterated elements is wrong. Passing and index of the array results in unpredictable results or ui not getting updated. Change this line from
v-bind:key="{index}"
to
v-bind:key="post.Post_ID"
Then, also how you are passing the data to the props is wrong, change from
v-bind:sendArticleData = post
to
v-bind:send-article-data="post"
or even simplier to:
:send-article-data="post"

CodePudding user response：
If I understood you correctly try like following snippet:
Vue.component('Child', {
template: `
<div >
<div >
<h4 >Kaerbran {{articleData.Post_Comment}}</h4>
</div>
</div>
`,
props : ['articledata'],
data() {
return {
articleData : this.articledata,
}
}
})
new Vue({
el: '#demo',
data() {
return {
