Answer 1

将其设为ListViewforReplies并简单地使用paginate_by.

class ThreadListView(ListView):

    model = Reply  #change the model

    template_name = 'forums/thread.html'

    paginate_by = 10  # add pagination on the list

    def get_queryset(self):

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

        return self.thread.replies.all().order_by('date_posted')

    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'] = self.thread

        return context

然后，在您的模板中，添加分页代码。使用object_list遍历回复

    <!--Reply Author and Content-->

        {% for rply in object_list %}  

....

<div class="container">

    {% if is_paginated %}

    {% if page_obj.has_other_pages %}

    <ul class="pagination justify-content-center" style="margin:20px 0">

        {% if page_obj.has_previous %}

        <li class="page-item"><a class="page-link" href="?page={{ page_obj.previous_page_number }}">Previous</a></li>

        {% else %}

        <li class="page-item disabled"><a class="page-link" href="#">Previous</a></li>

        {% endif %}

        {% for i in page_obj.paginator.page_range %}

        {% if page_obj.number == i %}

            <li class="page-item active"><a class="page-link" href="?page={{ i }}">{{ i }}</a></li>

        {% else %}

            <li class="page-item"><a class="page-link" href="?page={{ i }}">{{ i }}</a></li>

        {% endif %}

        {% endfor %}

        {% if page_obj.has_next %}

        <li class="page-item"><a class="page-link" href="?page={{ page_obj.next_page_number }}">Next</a></li>

        {% else %}

        <li class="page-item disabled"><a class="page-link" href="#">Next</a></li>

        {% endif %}

    </ul>

    {% endif %}

{% endif %}

</div>
