VueJS : v-for not rendering

Question

I'm trying vueJS (+ laravel) and i'm encountering a problem.

I made an OrdersComponent.vue with a v-for (for each order which I retrieved from my API), but nothing happens

OrderComponent.vue : (h1 is rendering, and console.log(this.orders) is working)

   <template>
    <div>
        <h1> Commandes </h1>
        <div class="card card-body" v-for="order in orders" v-bind:key="order.idCommande">
            <h2> {{ order.date }} </h2>
            <span> {{ order.statut }} </span>
        </div>
    </div>
</template>

<script>
import Vue from 'vue'
export default Vue.extend({
    data() {
        return {
            orders: [],
            order: {
                idCommande: '',
                date: '',
                prix: '', 
                statut: '',
            },
            orderId: '',
            edit: false
        }
    },

    methods: {
        fetchOrders() {
            fetch('api/orders')
                .then(res => res.json())
                .then(res => {
                    this.orders = res.data;
                    console.log(this.orders);
                })
        }
    },

    created() {
        this.fetchOrders();
    }
})
</script>

Page which call the component (orders.blade.php) :

@extends('layouts.app')

@section('content')
    <orders></orders>
@endsection

finally, layouts.app file :

<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">

Maybe you have already fixed it but in my case I was using an arrow function in methods but it was not working this way. I had to change it to "normal" function declaration like so:

methods: {
    fetchOrders: function() {
        fetch('api/orders').then(res => res.json())
        .then(res => {
            this.orders = res.data;
            console.log(this.orders);
        });
    }
},

Try to remove this from your component`s data() method:

        ...
        order: {
            idCommande: '',
            date: '',
            prix: '', 
            statut: '',
        },
        orderId: '',
        ...

You declare "order" in v-for section:

v-for="order in orders"

May be you forgot to recompile your app after making change.

Remove order object from data()

 order:{
  idCommande: '',
        date: '',
        prix: '', 
        statut: '',
 }

and recompile the app using:

npm run dev

Moreover: We create this kind of objects when we are going to submit some data using a form.

For example

For signup/register, we get user name, email, age, etc and save it into an object like below by calling each value in a template (e.g. user.name)

user:{
   name:'',
   email:'',
   age: '',
}

and then we just send user object via axios or fetch to the server.
