Question

当我尝试从表单发送数据到视图时，所有数据都成功发送，除了FileField Data。我正在使用模板的CURD数据表屏幕截图。我也使用ajax。我是Django的初学者，请帮助我找不到错误。

屏幕截图

view.py

def list(request):
    certificatedata = certificateDb.objects.all()
    context = {
    'certificatedata': certificatedata
    }
    return render(request, 'list.html',context)

def save_all(request,form,template_name):
    data = dict()
    if request.method == 'POST':
        if form.is_valid():
            form.save()
            data['form_is_valid'] = True

            certificatedata = certificateDb.objects.all()
            data['list'] = render_to_string('list_2.html',{'certificatedata':certificatedata})
        else:
            data['form_is_valid'] = False
    context = {
    'form':form
    }
    data['html_form'] = render_to_string(template_name,context,request=request)
    return JsonResponse(data)

def certificate_create(request):
    if request.method == 'POST':
        form = CertificateForm(request.POST, request.FILES )
        print('request.FILES',request.FILES)
    else:
        form = CertificateForm()
    return save_all(request,form,'certificate_create.html')

    class Meta:
