Django - 混合 ListView 和 CreateView

Question

我想用表单创建一个页面，每次提交表单时，它都会向表单下方的列表中添加一个项目。

我可以使用 2 页使其工作:

使用 mixin 的一页 CreateView添加项目

一页ListView有名单。

但我试图将表单和列表放在同一页面上。所以我尝试用两个 mixin 创建一个类:

class FormAndListView(ListView, CreateView):
    pass

然后我使用了这个类:

FormAndListView.as_view(
    queryset=PdfFile.objects.order_by('id'),
    context_object_name='all_PDF',
    success_url = 'listview',
    form_class = UploadFileForm,
    template_name='textfrompdf/index.html',)),

但是当我尝试加载页面时，出现错误: Exception Value: 'FormAndListView' object has no attribute 'object'

Traceback:
File "C:\Program Files\Python_2.7\lib\site-packages\django\core\handlers\base.py" in get_response
  111.                         response = callback(request, *callback_args, **callback_kwargs)

  122.         if self.object and self.template_name_field:

Exception Type: AttributeError at /PDF/
Exception Value: 'FormAndListView' object has no attribute 'object'

我不知道如何调试。从哪儿开始？

我使用了很多涉及表单和对象列表的 View 。而不是试图混合事物，我只是将查询集添加到上下文数据中，如下所示。

class UploadFileView(CreateView):
    form_class = UploadFileForm
    success_url = 'listview'
    template_name = 'textfrompdf/index.html'

    def get_context_data(self, **kwargs):
        kwargs['object_list'] = PdfFile.objects.order_by('id')
        return super(UploadFileView, self).get_context_data(**kwargs)
