The codes (below) must enable a user to comment on a post/page. Thus, the comment is linked to that page. But after the submit event, the comment is not saved, hence nothing is displayed except the comments from the Admin page.

Function that display the page and the comment in view.py

def list_page(request, list_id):
    if request.user.is_authenticated:
        list_auction = Auction_listings.objects.get(id=list_id)
        categories = Category.objects.get(id = list_id)
        return render(request, "auctions/auc_details.html", {
            "detail": list_auction,
            "cats":categories,
            "user": request.user,
            "comments": list_auction.comment.all(),
        })
    else:
        list_auction = Auction_listings.objects.get(id =list_id)
        return render(request, "auctions/auc_details.html", {
            "detail":list_auction
        })

comment function in view.py

def comment(request, list_id):
    if request.user.is_authenticated:
        list_auction = get_object_or_404(Auction_listings, pk=list_id)
        if request.method == "POST":
            comment_form = forms.Create_comment(request.POST)
            if comment_form.is_valid():
                com_t = comment_form.save(commit=False)
                com_t.comment = list_auction
                com_t.comment_by = request.user
                com_t.save()
                print(com_t)
                return HttpResponseRedirect(reverse("list_page", args=(list_auction.id,)))
                
        return render (request,"auctions/auc_details.html", {
            "detail": list_auction,
            "user": request.user,

html page

    <input type="text" name="text">
    <input type="hidden" name="auction_id" value="{{detail.id}}">
    <button type=" submit ">Create</button>
</form>

I tried to change the route to look like:

path("/comment/<int:list_id>", views.comment, name="comment"),

Tried But that didn't change anything.

CodePudding user response：

If you expect the comment to attach to list_auction there should be a connection between them

com_t.comment_on = list_auction

OR

com_t.comment_on_id = list_auction.id

in your case:

if comment_form.is_valid():
    com_t = comment_form.save(commit=False)
    com_t.comment = 'the text of comment'
    com_t.comment_on = list_auction
    com_t.comment_by = request.user
    com_t.save()
    print(com_t)
    return HttpResponseRedirect(reverse("list_page", args=(list_auction.id,)))
                

NOTE: For better debugging, check your database to see how the data is stored

CodePudding user response：

1. Call the Create_comment from form.py

def list_page(request, list_id):
    if request.user.is_authenticated:
        list_auction = Auction_listings.objects.get(id=list_id)
        categories = Category.objects.get(id = list_id)
        comment_form = forms.Create_comment()
        return render(request, "auctions/auc_details.html", {
            "detail": list_auction,
            "cats":categories,
            "user": request.user,
            "comments": list_auction.comment.all(),
            "com_form":comment_form,
        })
    else:
        list_auction = Auction_listings.objects.get(id =list_id)
        return render(request, "auctions/auc_details.html", {
            "detail":list_auction
        })

2 Call the ""com_form"" on the template.

<form action="{% url 'comment' detail.id %}" method="POST">
    {% csrf_token %}
   {{com_form}}
    <button type=" submit ">Create</button>
</form>
