Django-vue : Cannot correctly access the elements of the entity passed as params
I have several entities Order, Company, Products.
The Order table contains details including (Company, Products, Quantity...). But somehow I can't display some informations of the Order.
Here is my code in detail.
models.py
# model Company
class Companies(models.Model):
    company_id = models.AutoField(primary_key=True)
    order_number = models.CharField(max_length=500)
    company_name = models.CharField(max_length=500)
    company_email = models.CharField(max_length=500)
    class Meta:
        db_table ="companies"      

# model Product
class Products(models.Model):
    product_id = models.AutoField(primary_key=True)
    product_name = models.CharField(max_length=500)
    class Meta:
        db_table ="products"


# model Order
class Orders(models.Model):
    order_id = models.AutoField(primary_key=True)
    order_number = models.CharField(max_length=500)
    statut = models.CharField(max_length=500, default="validé")
    date_of_order = models.DateField()
    company = models.ForeignKey(Companies, on_delete = models.CASCADE)
    measure = models.ForeignKey(Measures, on_delete = models.CASCADE)
    products = models.ManyToManyField(Products, through='OrderDetail')
    class Meta:
        db_table ="orders"

# model OrderDetail
class OrderDetail(models.Model):
    order = models.ForeignKey(Orders, related_name='order_details', on_delete=models.CASCADE)
    product = models.ForeignKey(Products, related_name='order_details', on_delete=models.CASCADE)
    product_quantity = models.PositiveIntegerField(default=1)

    class Meta:
        db_table ="order_details

serializers.py
class OrderDetailsSerializer(serializers.ModelSerializer):
    product = ProductSerializer(read_only=True)
    company = CompanySerializer(read_only=True)

    class Meta:
        model = OrderDetail
        fields = '__all__'
        

class OrdersSerializer(serializers.ModelSerializer):
    order_details = OrderDetailsSerializer(many=True, read_only=True)
    products = ProductSerializer(many=True, read_only=True)
    company = CompanySerializer()

    class Meta:
        model = Orders
        fields = '__all__'

views.py
class OrderViewSet(viewsets.ModelViewSet):
    queryset = Orders.objects.all()
    serializer_class = OrdersSerializer

class OrderDetailsViewSet(viewsets.ModelViewSet):
    queryset = OrderDetail.objects.all()
    serializer_class = OrderDetailsSerializer

<script setup>
import axios from "axios";
import { useRoute } from "vue-router"

    const route = useRoute();
    const order_id = ref(route.params.order_id);

    const getSingleOrder = async () => {
        axios.get(API_URL + "orders-list/" + `${order_id.value}`)
          .then((response) => {
            order.value = response.data;
          })
          .catch((error) => {
            console.error(error);
          });
    };
onMounted(() => {
  getSingleOrder();
});
</script>

The orderorder_number, order_date are displayed, but what is :company_name, company_email, they don't display.
What did i do wrong in my code.
Thank you in advance
