只是尝试使用我在一个模板中使用的表单到另一个模板

所以我有这个评论表格在post.html中工作正常,现在我正在尝试在commentThread.html中使用它但我遇到了一些问题.(这已经困扰了我三天,任何帮助都将不胜感激)我会用我的代码解释一下

def post(request, slug):
        hotCat = Category.objects.get_hotCat()


        post = get_object_or_404(Post, slug=slug)
        post.views += 1  # increment the number of views
        post.save()      # and save it
        profile = post.moderator
        #path = request.get_full_path()
        #comments = Comment.objects.filter(path=path)
        comments_count = Comment.objects.filter(post=post).count()
        comments = post.commented_post.all()
        for c in comments:
                c.get_children()
        hidden_data = {
                    "post_id" : post.id,
                    "origin_path" : request.get_full_path,
                    "parent_id" : None
                }
        comment_form = CommentForm(hidden_data=hidden_data) 
        context_dict = {
            'post' :post,
            'hotCat' :hotCat,
            'comments' : comments,
            'comment_form':comment_form,
            'comments_count':comments_count,
            'profile' :profile,


        }
        return render(request, 'main/post.html', context_dict)

以上是我对post.html的功能.在主目录中.现在继续评论目录,我将发表评论表

class CommentForm(forms.Form):
    comment = forms.CharField(
        widget=forms.Textarea(attrs={"placeholder": "leave"})
    )
    #hidden_field = forms.CharField(widget=forms.HiddenInput())

    def __init__(self, hidden_data=None, data=None, files=None, **kwargs):
        super(CommentForm, self).__init__(data, files, kwargs)
        self.helper = FormHelper()
        self.helper.form_show_labels = False
        self.helper.add_input(Submit('submit', 'leave', css_class='btn btn-default'))
        if hidden_data:
            self.helper.add_input(Hidden('post_id', hidden_data['post_id']))
            self.helper.add_input(Hidden('origin_path', hidden_data['origin_path']))
            if hidden_data.get('parent_id', None):
                self.helper.add_input(Hidden('parent_id', hidden_data['parent_id']))

在评论目录中,这是我用于创建评论的views.py.它有两个部分,一个用于parent_comment,另一个用于回复parent_comment,我命名为child_comment.

现在在我的post.html中,我需要这两个功能.但是对于commentThread.html,显示了parent_comment,我想要一个允许用户回复parent_comment的表单.所以我在commentThread.html中需要的只是child_comment表单.

使用与post.html相同的方法,我为commentThread.html创建了视图,下面是我所做的,请让我知道我在这里做错了什么;

我尝试将相同的ajax功能放在那里,但没有区别..

==>页面刷新而不更改任何内容...显示没有错误它只是刷新...没有数据保存....]]

将表单包含<form></form> 在 html 中的标记内，就像在parent_comment.html 中所做的那样。并<script>在 commentThread.html 中使用 post.html 块。问题似乎是由于 commentThread.html 中缺少表单元素所致
