如何在帖子中添加评论？ PostDetailVew，Django 2.1.5

Question

我想在他的页面上添加评论（“发布详细信息”页面）。

我找到了答案，但它在其他页面上创建了评论。 我想在“帖子详细信息”页面上创建评论。

网址.py

url(r'^post/(?P<pk>\d+)/create/$', views.CommentCreate.as_view(), name='comment_create'),

模型.py

class Comment(models.Model):
    description = RichTextUploadingField()
    author = models.ForeignKey(User, on_delete=models.SET_NULL, null=True)
    comment_date = models.DateTimeField(auto_now_add=True, null=True)
    post = models.ForeignKey(Post, on_delete=models.CASCADE)

    class Meta:
        ordering = ["-comment_date"]

    def __str__(self):
        return "{}".format(self.description)

表格.py

class CommentForm(forms.ModelForm):
    class Meta:
        model = Comment
        fields = ['description']

视图.py

class PostDetailView(generic.DetailView):
    model = Post


class CommentCreate(LoginRequiredMixin, CreateView):
    model = Comment
    fields = ['description']

    def get_context_data(self, **kwargs):
        context = super(CommentCreate, self).get_context_data(**kwargs)
        context['post'] = get_object_or_404(Post, pk = self.kwargs['pk'])
        return context

    def form_valid(self, form):
        form.instance.author = self.request.user
        form.instance.post=get_object_or_404(Post, pk = self.kwargs['pk'])
        return super(CommentCreate, self).form_valid(form)

    def get_success_url(self):
        return reverse('post-detail', kwargs={'pk': self.kwargs['pk'],})

comment_form.html

...    
<form action="" method="post">
    {% csrf_token %}
    <table>
    {{ form.as_table }}
    </table>
    <button type="submit">Submit</button>
</form>
...

post_detail.html

...
{% for comment in post.comment_set.all %}
<p>{{ comment.author }} ({{ comment.comment_date }}) {{ comment.description|safe }}</p>
{% endfor %}
<hr>
{% if user.is_authenticated %}
<p><a href = "{% url 'comment_create' post.id %}">Add a new comment</a></p>
...

我认为，“comment_form”需要重定向到“post_detail”，而不是为评论表单生成新页面。

你能告诉我，哪些参数有 RichTextField (CKE)，如何只在评论中改变宽度、高度字段？

如果您希望在详细信息页面中直接使用评论表单，那么您所要做的就是在视图中添加表单和发布功能，

class PostDetailView(DetailView):
    model = Post
    template_name = 'yourdetailpage.html'

    def get_context_data(self, **kwargs):
       context = super(PostDetailView, self).get_context_data(**kwargs)
       context['commentform'] = CommentForm()
       return context

    def post(self, request, pk):
       post = get_object_or_404(Post, pk=pk)
       form = CommentForm(request.POST)

       if form.is_valid():
           obj  = form.save(commit=False)
           obj.post = post
           obj.author = self.request.user
           obj.save()
           return redirect('detail', post.pk)

现在您可以在 html 中添加表单。 并添加一个提交按钮来发表评论。
