Django 3.1分页中的空白页

问题描述

我实现了Django分页功能，可在我的网站上切片搜索结果。

# views.py
def search(request):

    # Keywords
    if 'keywords' in request.GET:
        keywords = request.GET['keywords']
        if keywords:
            title_list_control_valve = queryset_list.filter(title__icontains=keywords).order_by('title')  
            description_list_control_valve = queryset_list.filter(description__icontains=keywords).order_by('description').distinct('description')
           
            result_list_control_valves = list(chain(title_list_control_valve,description_list_control_valve))
        
            result_list_control_valves_2 = list(dict.fromkeys(result_list_control_valves))

            paginator = Paginator(result_list_control_valves_2,1)  
            page = request.GET.get('page')
            paged_queries = paginator.get_page(page)

            context = {
                'queries': paged_queries,}

            return render(request,'pages/search.html',context)
        else:
            return render(request,'pages/search.html')
    else:
        return render(request,'pages/search.html')

显示搜索结果时网站的URL是：

http://localhost:8000/pages/search/?keywords=something

它仅在首页上运行良好。从第二页开始，它显示一个空白页，该站点的URL更改为：

http://localhost:8000/pages/search/?page=2

我链接到HTML中的其他页面，如下所示：

<div class="col-md-12">
    
    {% if queries.has_other_pages %}
    
      <ul class="pagination">
        {% if queries.has_prevIoUs %}
          <li class="page-item">
            <a href="?page={{queries.prevIoUs_page_number}} " class="page-link">&laquo;</a>
          </li>
        {% else %}
          <li class="page-item disabled">
            <a class="page-link">&laquo;</a>
          </li>
        {% endif %}
        {% for i in queries.paginator.page_range %}
          {% if queries.number == i %}
            <li class="page-item active">
              <a class="page-link">{{i}}</a>
            </li>
          {% else %}
            <li class="page-item">
              <a href="?page={{i}} " class="page-link">{{i}}</a>
            </li>
          {% endif %}
        {% endfor %}
        {% if queries.has_next %}
          <li class="page-item">
            <a href="?page={{queries.next_page_number}}" class="page-link">&raquo;</a>
          </li>
        {% else %}
          <li class="page-item disabled">
            <a class="page-link">&raquo;</a>
          </li>
        {% endif %}
      </ul>

    {% endif %}
</div>

URL的?keywords=something部分消失了。

有问题吗？

如何使其他页面的链接也起作用？

解决方法

将keywords添加到您的GET参数中。对于前。 href="?page={{queries.previous_page_number}}&keywords={{request.GET.keywords}}"
