可以发布文章，也有发布成功的提示，再尝试创建同样标题的文章也会正确地提示标题已存在，但无论是文章页还是草稿页，见不到一篇文章，只有“快来成为第一个写文章的吧！”

代码如下

# views.py

import ...

class ArticleListView(LoginRequiredMixin, ListView):
    """已发布的文章的列表"""

    model = Article
    paginate_by = 10
    context_object_name = 'articles'

        context = super(ArticleListView, self).get_context_data(*args, **kwargs)
        context['popular_tags'] = Article.objects.get_counted_tags()
        return context

    queryset = Article.objects.get_published()


class DraftListView(ArticleListView):
    '''草稿箱文章列表'''

    def get_queryset(self) -> QuerySet[Any]:

    '''发表文章'''

    model = Article
