django中Paginator分页的简单实现

views中使用分页库Paginator.page

先导入Page, Paginator
from django.core.paginator import Page, Paginator
def paper(request,topic_id):
    #获取对应主题对象
    topic_t = Topic.objects.get(id=topic_id)
    #展示对象
    paper_qs = topic_t.paper.paper_quest.all()
    #分页器,每页显示1条记录
    paginator = Paginator(paper_qs,1)
    #获取用户页面的页数
    page = request.GET.get('page')
    try:
  # GET请求方式，get()获取指定Key值所对应的value值
  # 获取index的值，如果没有，则设置使用默认值1
        contacts = paginator.page(page)
    except PageNotAnInteger:
  # 如果输入的页码数不是整数，那么显示第一页数据
        contacts = paginator.page(1)
    except EmptyPage:
        contacts = paginator.page(paginator.num_pages) 
    context = {
        #分页对象
        'contacts':contacts
    return render(request,'quest/paper.html',context)

模板页面:paper.html

"""翻页栏"""
<div class="pagination" >
      <span class="step-links">
        {% if contacts.has_previous %}
            <a href=" ?page={{ contacts.previous_page_number }}">previous</a>
        {% endif %}
        <span class="current">
              Page {{ contacts.number }} of {{ contacts.paginator.num_pages }}.
        </span >
          {% if contacts.has_next %}
            <a href=" ?page={{ contacts.next_page_number }}">next</a>
          {% endif %}
"""读取每页的内容,并通过属性展示出来,添加按钮变成点击获取和传递值,并打开下一页."""
      {% for contact in contacts %}
      {# Each "contact" is a Contact model object. #}
        {% if contacts.has_next %}
        <var> {{contact.id}} </var>{{contact}}
          <p><button type="button" class="btn btn-default btn-lg btn-block" id="b1" 
            value="{{contact.answer_A_score}}" 
"""使用ajax传递按钮数据,同时传递其他变量到views的compute函数
   <script>
      var topic_id = {{ topic_t.id }};
      var quest_id = {{ contacts.number }};
      $("#b1").click(function () {
          $.ajax({  
              url: " {% url 'quest:compute' %} ", 
              type: "post",
              data: {
                  "id": $("#b1").val(),
                  "topic_id":topic_id,
                  "quest_id":quest_id,
                  "csrfmiddlewaretoken": $("[name='csrfmiddlewaretoken']").val()
              },
              success: function (res){
                  $('#m1').val(res)
              },
              error: function (err) {
                  console.log(err);
              }
          })
      })
    </script>

tips :

需要在js中先将定义变量,才能传递var

分页实例对象contacts可以获取值,但是在循环中contact实例在页面可以展示,但是不能获取值,不明白为什么?。。。。。。因为没有var
