    template_name = 'forums/thread.html'

    def get_context_data(self, **kwargs):

        # Call the base implementation first to get a context

        context = super().get_context_data(**kwargs)

        # Add in a QuerySet of the Thread & Replies

        context['thread'] = Thread.objects.get(pk=self.kwargs['pk'])

        context['reply'] = Thread.objects.get(pk=self.kwargs['pk']).replies.all()

我想对线程 ListView 进行分页。

Thread ListView 显示 Thread，然后显示该线程上的回复。

我希望能够将所有内容分成页面。

例如，线程以 Thread 帖子和 10 个回复开始，然后要查看一些较新的回复，您可以单击下一页。

将其设为ListViewforReplies并简单地使用paginate_by.class ThreadListView(ListView):&nbsp; &nbsp; model = Reply&nbsp; #change the model&nbsp; &nbsp; template_name = 'forums/thread.html'&nbsp; &nbsp; paginate_by = 10&nbsp; # add pagination on the list&nbsp; &nbsp; def get_queryset(self):&nbsp; &nbsp; &nbsp; &nbsp; self.thread = Thread.objects.get(pk=self.kwargs['pk'])&nbsp; &nbsp; &nbsp; &nbsp; return self.thread.replies.all().order_by('date_posted')&nbsp; &nbsp; def get_context_data(self, **kwargs):&nbsp; &nbsp; &nbsp; &nbsp; # Call the base implementation first to get a context&nbsp; &nbsp; &nbsp; &nbsp; context = super().get_context_data(**kwargs)&nbsp; &nbsp; &nbsp; &nbsp; # Add in a QuerySet of the Thread & Replies&nbsp; &nbsp; &nbsp; &nbsp; context['thread'] = self.thread&nbsp; &nbsp; &nbsp; &nbsp; return context然后，在您的模板中，添加分页代码。使用object_list遍历回复...&nbsp; &nbsp; <!--Reply Author and Content-->&nbsp; &nbsp; &nbsp; &nbsp; {% for rply in object_list %}&nbsp;&nbsp;....<div class="container">&nbsp; &nbsp; {% if is_paginated %}&nbsp; &nbsp; {% if page_obj.has_other_pages %}&nbsp; &nbsp; <ul class="pagination justify-content-center" style="margin:20px 0">&nbsp; &nbsp; &nbsp; &nbsp; {% if page_obj.has_previous %}&nbsp; &nbsp; &nbsp; &nbsp; <li class="page-item"><a class="page-link" href="?page={{ page_obj.previous_page_number }}">Previous</a></li>&nbsp; &nbsp; &nbsp; &nbsp; {% else %}&nbsp; &nbsp; &nbsp; &nbsp; <li class="page-item disabled"><a class="page-link" href="#">Previous</a></li>&nbsp; &nbsp; &nbsp; &nbsp; {% endif %}&nbsp; &nbsp; &nbsp; &nbsp; {% for i in page_obj.paginator.page_range %}&nbsp; &nbsp; &nbsp; &nbsp; {% if page_obj.number == i %}&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <li class="page-item active"><a class="page-link" href="?page={{ i }}">{{ i }}</a></li>&nbsp; &nbsp; &nbsp; &nbsp; {% else %}&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <li class="page-item"><a class="page-link" href="?page={{ i }}">{{ i }}</a></li>&nbsp; &nbsp; &nbsp; &nbsp; {% endif %}&nbsp; &nbsp; &nbsp; &nbsp; {% endfor %}&nbsp; &nbsp; &nbsp; &nbsp; {% if page_obj.has_next %}&nbsp; &nbsp; &nbsp; &nbsp; <li class="page-item"><a class="page-link" href="?page={{ page_obj.next_page_number }}">Next</a></li>&nbsp; &nbsp; &nbsp; &nbsp; {% else %}&nbsp; &nbsp; &nbsp; &nbsp; <li class="page-item disabled"><a class="page-link" href="#">Next</a></li>&nbsp; &nbsp; &nbsp; &nbsp; {% endif %}&nbsp; &nbsp; </ul>&nbsp; &nbsp; {% endif %}{% endif %}</div>
