Django文件未上传在打印时获取<MultiValueDict：{}> Django 3.1

如何解决Django文件未上传在打印时获取<MultiValueDict：{}> Django 3.1

我尝试使用Django上传文件，但无法执行。有人可以告诉我此代码文件出了什么问题吗？ 所有代码文件都在这里，

views.py

@method_decorator(login_required,name='dispatch')
class CreatePost(View):

    def post(self,request,boardId):
        postTitle = request.POST.get('postTitle')
        postDescription = request.POST.get('postDescription')
        print(postTitle )
        print(postDescription)
        createdOn = datetime.Now()
        createdBy = request.user
        boardId = BoardModel.objects.get(boardId = boardId)

        newPost = Post(
                postTitle = postTitle,postDescription = postDescription,createdOn = createdOn,createdBy = createdBy,boardId = boardId,)
        newPost.save()

        postId = newPost.postId
        request_file = request.FILES['postAttachment'] if 'postAttachment' in request.FILES else None
        print(request.FILES)
        if request_file:
            print(request.POST['postAttachment'])
            storeAt = settings.STATIC_DIR
            fs = FileSystemStorage(storeAt)
            filename = request.POST['postAttachment']
            file = fs.save(filename,request_file)

        print("boardId in create post" + str(boardId))

        return redirect(request.Meta['HTTP_REFERER'])

模板

<form action="{% url 'create_post' boardId=board.boardId %}" method="POST" enctype="multiple/form-data">

{% csrf_token %}
<input type="text" name="postTitle" id="id_postTitle" placeholder="Enter The Post Title" class="form-control form-input" required>
<be>
<textarea name="postDescription" id="postForm" cols="3" class="form-control" style="resize: vertical; height: 100px;" placeholder="Enter Post Description" cols="5" required></textarea>
<br>
<span id="attachedFilesList" class="row"></span> 
<br>
<button type="submit" class="btn btn-login btn-green" id="postBtn"><span>Post</span></button>
<input type="file" name="postAttachment" id="fileUpload" onchange="previewFiles(event);">
&nbsp;&nbsp;

在打印请求时。文件我得到了

输出（cmd）：
