如何使我的回复表单接收输入的Django？

Question

大家好，我正在制作一个回复表单，用户可以从中回复评论，我使用评论表单两次，第一次是评论本身，第二次是回复。但是当我初始化回复表单时，它给了我模型的数据。它不会显示为表单

这是评论和回复的TextBox

models.py

这是评论和回复的views.py

class CommentManager(models.Manager):

    def all(self):
        qs = super(CommentManager,self).filter(parent = None)
        return qs

class Comment(models.Model):
    post = models.ForeignKey(Post,on_delete=models.CASCADE,related_name = "comments")
    name = models.CharField(max_length = 200)
    body = models.TextField(default = True)
    pub_date = models.DateTimeField(auto_now_add = True)
    parent = models.ForeignKey('self',null = True,blank = True)


    class Meta:
        ordering = ['-pub_date']


    def __str__(self):
        return self.name


    def replies(self):
        return  Reply.objects.filter(parent = self)


    @property
    def is_parent(self):
        if self.parent is not None:
            return False
        return True 

这是评论表单的forms.py

    def BlogDetail(request,pk):

        post = get_object_or_404(Post,pk = pk) 
        comment = CommentForm(

request.POST or None)
    subscribe = Subscribe() 
    parent_obj = None


    if request.method  == 'POST':
        subscribe = Subscribe(request.POST) 
        comment = CommentForm(request.POST)


        if comment.is_valid():
            comment.instance.post = post
            comment.save()  

            return redirect('index')


            try:
               parent_id = request.POST.get('parent_id')
            except:
               parent_id = None

            if parent_id:
               parent_qs = Comments.objects.filter(id = parent_id)
            if parent_qs.exits():
               parent_obj = parent_qs.first()



        elif subscribe.is_valid():
           subscribe = subscribe.save(commit = True)
           return redirect('index')


    return render(request,'app/blog.html',{'blog_object':post,'comment':comment,
        'subscribe':subscribe,'parent':parent_obj,
        })

这是评论部分的html

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

        widgets = {

        'body':forms.Textarea(attrs = {'class':'form-control','placeholder':'You,r comment','minlength':'20'}),
        'name': forms.TextInput(attrs = {'class':'form-control','placeholder':'You,r name','minlength':'5'})


        }

在评论部分正下方的是html答复

<div class="comments">
            <div class="row">
                <div class="container"> 
                </div>
                <form action="." method="post" id="commentform" class="comment-form" >
                    {% csrf_token %}

                    <div class="col">
                        <div class="form-group form-group-with-icon comment-form-email">
                            {{comment}}
                            <div class="form-control-border"></div>
                        </div>
                    </div>  

                    <div class="col">
                        <p class="form-submit">
                            <input name="submit" type="submit" id="submit" class="submit"value="Post Comment">
                        </p>
                    </div>
                </form>
            </div>


            <div class="post-comments">
                <h3  style = "color: #ff714a; font-weight:300;">See the latest comments</h3>
                {% for comment in blog_object.get_comments %}
                <div class="container">
                    <div class="row">
                        <div class="col comment_head">
                            <strong>{{comment.name}}</strong>

                            <div class="col comment_body">
                                <p>{{comment.body}}</p>
                            </div> 
                        </div>                          
                    </div>
                    <div class="border"></div>
