Django分页“未找到页面”

我目前正在处理我的Django分页问题。我有一个9个对象的查询集,并将一个对象分页到一个页面。所以我应该总共有9页。

Paginator显示我有9页,但是当我点击“下一页”页面按钮时我的(总是在最后/最后两页)我的网址转到:http://127.0.0.1:8000/forum/1?page=7

然后我得到404页面未找到错误以及“无效页面(7):该页面不包含任何结果”

这是我的班级代码:

class DirectoryClass(generic.ListView):
    template_name = "forum_directory.html"
    model = Directory
    paginate_by = 1

    def get_context_data(self, **kwargs):
        context = super(DirectoryClass, self).get_context_data(**kwargs)
        directory = Directory.objects.filter(pk=self.kwargs['directory_id'])
        context['page'] = 'forum'
        context['name'] = directory.first().name
        context['user'] = self.request.user
        topic_set = directory.first().topic_set.all().order_by('-last_post')
        print(topic_set.all())
        paginator = Paginator(topic_set, self.paginate_by)
        page = self.request.GET.get('page')
        try:
            topic_set = paginator.page(page)
        except PageNotAnInteger:
            topic_set = paginator.page(1)
        except EmptyPage:
            topic_set = paginator.page(paginator.num_pages)
        context['topics'] = topic_set
        context['page'] = page
        return context

以下是用于更改页面的HTML:

<div style="width: 1240px; margin: auto; text-align: right;">
    {% if topics.has_other_pages %}
      <ul class="pagination forum-pagination">
        {% if topics.has_previous %}
          <li><a href="?page={{ topics.previous_page_number }}">&laquo;</a></li>
        {% else %}
          <li class="disabled"><span>&laquo;</span></li>
        {% endif %}
        {% for i in topics.paginator.page_range %}
          {% if topics.number == i %}
            <li class="active"><span>{{ i }} <span class="sr-only">(current)</span></span></li>
          {% else %}
            <li><a href="?page={{ i }}">{{ i }}</a></li>
          {% endif %}
        {% endfor %}
        {% if topics.has_next %}
          <li><a href="?page={{ topics.next_page_number }}">&raquo;</a></li>
        {% else %}
          <li class="disabled"><span>&raquo;</span></li>
        {% endif %}
      </ul>
    {% endif %}
</div>

这是网址

    path(r'/<int:directory_id>',views.DirectoryClass.as_view(), name='forum_directory'),

我在这里做错了什么?

答案 0 :(得分:1)

def get_context_data(self, **kwargs):
        context = super(DirectoryClass, self).get_context_data(**kwargs)

        context['page'] = 'forum'
        context['user'] = self.request.user

        return context

def get_queryset(self):
    directory = Directory.objects.filter(pk=self.kwargs['directory_id'])
    topics = directory.first().topic_set.all().order_by('-last_post')
    return topics

仅在ListView中使用它,因为Django为所有基于类的视图提供分页
