I am adding a comment section for my posts, the issue is after submitting it leads to HTTP ERROR 405 This is the first time to receive this error, I have reviewed the views several times but I think the error might be from the views.py in post detail view

class PostDetailView(DetailView):
    model = Post
    template_name = "post_detail.html"

    def get_context_data(self, *args, **kwargs):
        context = super(PostDetailView, self).get_context_data()
        post = get_object_or_404(Post, slug=self.kwargs['slug'])
        comments = Comment.objects.filter(post=post).order_by('-id')
        total_likes = post.total_likes()
        liked = False
        if post.likes.filter(id=self.request.user.id).exists():
            liked = True

        if self.request.method == 'POST':
            comment_form = CommentForm(self.request.POST or None)
            if comment_form.is_valid():
                content = self.request.POST.get('content')
                comment = Comment.objects.create(
                    post=post, user=request.user, content=content)
                comment.save()
                return HttpResponseRedirect("post_detail.html")
        else:
            comment_form = CommentForm()

        context["total_likes"] = total_likes
        context["liked"] = liked
        context["comments"] = comments
        context["comment_form"] = comment_form
        return context

here is the template


            <div class="main-comment-section">
            {{comments.count}} Comment{{comments|pluralize}}
            {% for comment in comments %}
            <blockquote class="blockquote">
                <p class="mb-0"> {{ comment.content}}</p>
                <footer class="blockquote-footer">by<cite title="Source Title">{{comment.user| capfirst}}</cite></footer>
            </blockquote>
            {% endfor %}

here are the comments models.py

class Comment(models.Model):
    post = models.ForeignKey(Post, on_delete=models.CASCADE)
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    content = models.TextField(max_length=160)
    timestamp = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return '{}-{}'.format(self.post.title, str(self.user.username))

where is the form submission? .. what is your initial analysis on this?

Submitted 1 year, 12 months ago

I have been trying to follow the logic of a function to be implemented in my classed view

- ahmed.hisham87 1 year, 12 months ago

if you still want to stick with this approach , lets add print statement here if self.request.method == 'POST': comment_form = CommentForm(self.request.POST or None) if comment_form.is_valid(): content = self.request.POST.get('content') comment = Comment.objects.create( post=post, user=request.user, content=content) comment.save() print('Its working') return HttpResponseRedirect("post_detail.html")

any update on this?

- arun 1 year, 12 months ago

it did not print

- ahmed.hisham87 1 year, 12 months ago

Method Not Allowed (POST):

- ahmed.hisham87 1 year, 12 months ago

exactly as its DetailedView, its not allowing to POST, as i mentioned above, can you use different view for POST the comment

- arun 1 year, 12 months ago

how do you suggest to do it?

- ahmed.hisham87 1 year, 12 months ago

create another function based view & submit the comment over there and redirect to whatever the page you like to

- arun 1 year, 12 months ago

or try this ```def post(self, request, args, *kwargs): form = CommentForm(request.POST, request.FILES) if form.is_valid(): # Write Your Logic here

    self.object = self.get_object()
    context = context = super(Detail, self).get_context_data(**kwargs)
    context['form'] = CommentForm
    return self.render_to_response(context=context)

else:
    self.object = self.get_object()
    context = super(Detail, self).get_context_data(**kwargs)
    context['form'] = form
    return self.render_to_response( context=context)```

if you still want to stick with DetailView itself then use above logic

i hope this one fix your issue

I am getting somewhere but I got Exception Value: post() got an unexpected keyword argument 'slug'

- ahmed.hisham87 1 year, 12 months ago

show me the code?

- arun 1 year, 12 months ago

I think this is right ``` def get_context_data(self, args, *kwargs): context = super(PostDetailView, self).get_context_data() post = get_object_or_404(Post, slug=self.kwargs['slug']) comments = Comment.objects.filter(post=post).order_by('-id') total_likes = post.total_likes() liked = False if post.likes.filter(id=self.request.user.id).exists(): liked = True

    if self.request.method == 'POST':
        comment_form = CommentForm(self.request.POST or None)
        if comment_form.is_valid():
            content = self.request.POST.get('content')
            comment = Comment.objects.create(
                post=post, user=self.request.user, content=content)
            comment.save()
            return HttpResponseRedirect("post_detail.html")
    else:
        comment_form = CommentForm()

    context["total_likes"] = total_likes
    context["liked"] = liked
    context["comments"] = comments
    context["comment_form"] = comment_form
    return context

def post(self, request, args, *kwargs):
    form = CommentForm(request.POST, request.FILES)
    if form.is_valid():  # Write Your Logic here
        self.object = self.get_object()
        context = context = super(
            PostDetailView, self).get_context_data(**kwargs)
        context['form'] = CommentForm
        return self.render_to_response(context=context)
    else:
        self.object = self.get_object()
        context = super(PostDetailView, self).get_context_data(**kwargs)
        context['form'] = form
        return self.render_to_response(context=context)

```

so you are able to render the detail view but not able to POST right?

- arun 1 year, 12 months ago

no I am getting post() got an unexpected keyword argument 'slug' with a wrong url http://127.0.0.1:8000/score/score/hthththt76/

- ahmed.hisham87 1 year, 12 months ago

I quickly reproduce the logic , see below its perfectly working to me. you can check at your end with slight change instead id, it should be slug, class DetailPostView(DetailView): model = Post template_name = 'tutorial/tutorial_detail.html' fields = ['title']

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        # favorite = Favorite.objects.filter(add_favorite=True)
        form = CommentForm(self.request.POST or None)
        id = self.kwargs['pk']
        obj_post = Post.objects.get(id=id)
        context['form'] = form
        return context

    def post(self, request, *args, **kwargs):
        form = CommentForm(request.POST, None)
        if form.is_valid():
        # Write Your Logic here
            print('Its Saved')
            self.object = self.get_object()
            context = super(DetailPostView, self).get_context_data(**kwargs)
            return self.render_to_response(context=context)

I have followed your logic and amended somethings : The views: ``` class PostCommentCreateView(CreateView): model = Comment fields = ['content']

def get(self, request, slug, *args, **kwargs):
    raise Http404

def post(self, request, slug, *args, **kwargs):
    self.post = Post.objects.get_or_404(slug=slug) <-----Error 'Manager' object has no attribute 'get_or_404'
    self.user = request.user

    super().post(request, *args, **kwargs)

def form_valid(self, form):
    form.instance.post = self.post
    form.instance.user = self.user
    return super(PostCommentCreateView, self).form_valid(form)

Here is the urls: path('post/<slug:slug>/comment', PostCommentCreateView.as_view(), name='post-comment'), here is the template: <form action={% url 'score:post-comment' post.slug %} method="post" class="comment-form" action=".">
{% csrf_token %} {{ comment_form.as_p }} {% if request.user.is_authenticated %} <input type="submit" value="Submit" class="btn btn-outline-success"> {% else %} <input type="submit" value="Submit" class="btn btn-outline-success" disabled> You must be Logged in to Comment {% endif %} </form> ```

why you are sending slug to POST.. see if its POST request then you just need to save the data using the form just like below def post(self, request, args, *kwargs): form = TaskForm(request.POST, None) if form.is_valid(): new_form = form.save(commit=False) new_form.user = request.user new_form.save()

    return redirect('/todo/')

Thank you for this solution really appreciate it ``` class PostCommentCreateView(LoginRequiredMixin, CreateView): model = Comment fields = ['content', ] success_url = reverse_lazy('score:post-detail')

def post(self, request, *args, **kwargs):
    form = CommentForm(request.POST)
    if form.is_valid():
        post = form.save()
        post.save()
    print(args, kwargs, request.POST)
    return redirect('score:post-detail', slug=kwargs['slug'])

```

right way to submit the comment form to different views not to same Detailed view. That is not recommended one
