Salut je suis entrai de créer mon blog avec le framework django et c'est difficile pour moi d'insérer la clé secondaire de l'article dans le Table Commentaire

views.py
Code:
def indexView(request):
    form = FriendForm()
    friends = Friend.objects.all()
    return render(request, "blog/testajax.html", {"form": form, "friends": friends})

def postFriend(request):
    # request should be ajax and method should be POST.
    if request.is_ajax and request.method == "POST":
        # get the form data
        form = FriendForm(request.POST, ser_instance=Article.objects.get(pk=article.id))
        # save the data and after fetch the object in instance
        if form.is_valid():
            instance = form.save()
            # serialize in new friend object in json
            ser_instance = serializers.serialize('json', [ instance, ])
            # send to client side.
            return JsonResponse({"instance": ser_instance}, status=200)
        else:
            # some form errors occured.
            return JsonResponse({"error": form.errors}, status=400)

    # some error occured
    return JsonResponse({"error": ""}, status=400)
code ajax

Code:
$("#friend-form").submit(function (e) {
        // preventing from page reload and default actions
        e.preventDefault();
        // serialize the data for sending the form data.
        var serializedData = $(this).serialize();
        // make POST ajax call
        console.log(serializedData);
        $.ajax({
            type: 'POST',
            url: "{% url 'blog:post_friend' %}",
            data: serializedData,
            success: function (response) {
                $("#contact-form").trigger('reset');
                $("#succes").text('Vore message à bien été envoyé').css('background-color', 'lightblue');
                
            },
            error: function (response) {
                alert(response["responseJSON"]["error"]);
            }
        })
    })
