class ThreadListView(ListView):
    model = Thread
    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()
        return context

我想对 Thread 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拆分成页面。

例如，话题以话题 post 和 10 个回复开头，然后要查看一些较新的回复，您可以单击下一页。

Answer 1

将其设为 Replies 的 ListView 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>
