如何在FormView中將FormView實現為Django

Question

我使用基於Django的視圖。 我有一個顯示對象（DetailView）的類，現在我想將表單添加到同一頁面，就像在DetailView中一樣。

我的views.py：

class CommentFormView(FormView):
    form_class = AddCommentForm
    success_url = '/'

class BlogFullPostView(CommentFormView, DetailView):
    model = Post
    template_name = 'full_post.html'
    pk_url_kwarg = 'post_id'
    context_object_name = 'post'

    def get_context_data(self, **kwargs):
        context = super(BlogFullPostView, self).get_context_data(**kwargs)
        context['comments'] = Comment.objects.filter(post=self.object)
        return context

也許您了解-BlogFullPostView-顯示頁面，我想在其中添加表單。 CommentFormView-查看評論。

我的表格：

class AddCommentForm(forms.ModelForm):
    class Meta:
        model = Comment
        fields = ('content',)
        widgets = {
            'content': forms.TextInput(attrs={
                'class': 'form-control'
            })
        }

        labels = {
            'content': 'Content'
        }

    def __init__(self, *args, **kwargs):
        super(AddCommentForm, self).__init__(*args, **kwargs)

因此，在模板中，我嘗試添加表單：

<form method="post" action="" role="form">
     {{ form }}
</form>

它不顯示任何內容:(

我該怎么辦？

我不會嘗試在單個視圖中混合兩個用例的邏輯。

class BlogFullPostView(DetailView):
    model = Post
    template_name = 'full_post.html'
    pk_url_kwarg = 'post_id'
    context_object_name = 'post'

    def get_context_data(self, **kwargs):
        context = super(BlogFullPostView, self).get_context_data(**kwargs)
        context['comments'] = Comment.objects.filter(post=self.object)
        context['form'] = AddCommentForm(initial={'post': self.object })
        return context

class CommentFormView(FormView):
    form_class = AddCommentForm

    def get_success_url(self):
        # logic here for post url 


# full_post.html

<form method="post" action="{% url "comment_form_view_url" %}">
    {{ form }}
</form>
