How to read deep JSON data using Vuejs and Axios - vue.js

Question

How would I read deep JSON data nested deep inside a file? I've tried different methods and can't seem to get this to work.
<template>
<div>
<div v-for="edu in info" :key="edu">
<div>{{ edu.section.title }}</div> // this is what im trying to get to work
</div>
<div class="card container">
{{ info }}
</div>
</div>
</template>
<script>
import axios from 'axios';
export default {
data() {
return {
info: null
}
},
mounted() {
axios
.get('./calculus.json') // Data Below
.then(response => (this.info = response.data.edu))
.catch(error => console.log(error))
}
}
</script>
My JSON looks like this:
{
"edu": {
"1": {
"title": "Title One",
"subtitle": "Subtitle One",
"description": "Description One",
"section": {
"1": {
"title": "Section One Title",
"content": "Section One Content"
}
}
},
"2": {
"title": "Title Two",
"subtitle": "Subtitle Two",
"description": "Description Two",
"section": {
"1": {
"title": "Section One Title",
"content": "Section One Content"
}
}
}
}
}
How can I use vue-for and get the data inside the section to get it to display under the title? For example: title, section>title, section>subtitle, etc.

Answer 1

Given each section is also an object with weird numeric keys, you can iterate them in the same way you do info.
I would also advise you to use identifiable values instead of the entire edu object in your :key bindings.
<div v-for="(edu, eduId) in info" :key="eduId">
<div v-for="(section, sectionId) in edu.section" :key="sectionId">
{{ section.title }}
</div>
</div>
If possible, I would alter the format of your JSON data to use actual arrays instead of objects with numeric keys.

Answer 2

One way to browse your object deeply is to cumulate v-for on your object (and children) entries.
ie:
<div v-for="([category, books], catkey) in Object.entries(info)" :key="`category-${catkey}`">
<div>{{ category }} :</div>
<div v-for="([num, book], numkey) in Object.entries(books)" :key=`book-${catkey}-${numkey}`>
<div v-for="([field, value], valkey) in Object.entries(book)" :key=`field-${catkey}-${numkey}-${valkey}`>
{{ field }} : {{ value }}
</div>
</div>
</div>
If you find it too verbose, you may try to flatten your computed data to have the following structure:
[
{
"category": "edu",
"id": "1",
"title": "Title One",
"subtitle": "Subtitle One",
"description": "Description One",
"section": {
"1": {
"title": "Section One Title",
"content": "Section One Content"
}
}
}
]
