具有分页和复选框的Python / Django数据表

我是python / django的新手，我从其他页面选择所有对象时遇到问题，我只能从当前页面中选择它们 . 希望有人帮助我.. Example

继承我的代码：

@login_required(login_url='/login/')
def index(request):
    title = 'Tags'
    tag_list = Tags.objects.all()
    paginator = Paginator(tag_list, 10)

    page = request.GET.get('page')
    try:
        tags = paginator.page(page)
    except PageNotAnInteger:
        tags = paginator.page(1)
    except EmptyPage:
        tags = paginator.page(paginator.num_pages)
    return render(request, 'tag/index.html' , {'tags':tags, 'title':title})

js的复选框：

<script language="JavaScript">
function toggle(source) {
  checkboxes = document.getElementsByName('selected');
  for(var i=0, n=checkboxes.length;i<n;i++) {
    checkboxes[i].checked = source.checked;
  }
}
</script>

的index.html

<form action="{% url 'tag:selected' %}" method="get">
  <table id="dt" class="table table-bordered table-hover responsive" style="text-align:center;">
    <thead>
      <tr>
        <th><input type="checkbox" onClick="toggle(this)"></th>
         <th></th>
        <td>Name</td>
          <td>Frequency</td>
      </tr>
    </thead>
    <tbody>
    {% for tags in tags %}

      <tr>
        <td><input type="checkbox"  name="selected" value="{{ tags.id}}"></td>
          <td><a href="{% url 'tag:detail' tags.id %}"> <img src="{{ tags.tag_image.url }}" style="display:block;
width: 80px; height:80px; margin:auto;"></a></td>
        <td>{{ tags.tag_name }}</td>
        <td>{{ tags.tag_frequency}}</td>
      </tr>

    {% endfor %}
    </tbody>
  </table><input class="btn btn-primary" style="float:right; margin-right:5%; margin-bottom:2%; margin-top:-3%; "type="submit" value="Submit">
                        </form>


<div class="pagination">
    <span class="step-links">
        {% if tags.has_previous %}
            <a href="?page={{ tags.previous_page_number }}">previous</a>
        {% endif %}

    <span class="current">
        Page {{ tags.number }} of {{ tags.paginator.num_pages }}
    </span>
    {% if tags.has_next %}
        <a href="?page={{ tags.next_page_number }}">next</a>
    {% endif %}
    </span>
</div>
