我有一个根据日期提交表单的代码。每当我在表单上使用分页时都会显示错误
"Key 'userchoice' not found in <QueryDict: {}>"
分页限制数据正确显示,但是当我单击“下一步”时,它会显示错误。
这是我到目前为止所得到的:
视图.py:-
def testeruser(request):
    getchoice = request.POST['userchoice']
    getfirstdate = request.POST['firstdate']
    getseconddate = request.POST['seconddate']
#   getfirstdate = '2013-09-25'
#   getseconddate = '2013-09-26'
    if getchoice == '0':
        getdata = applicationform.objects.filter(date__gte=getfirstdate , date__lte=getseconddate)
        ##### PAGINATION
        searchpagination = Paginator(getdata ,3)
        page=request.GET.get('searchpage')
        try:
            searchcontacts = searchpagination.page(page)
        except PageNotAnInteger:
            searchcontacts = searchpagination.page(1)
        except EmptyPage:
            searchcontacts = searchpagination.page(searchpagination.num_pages)  
        if getdata:
            return render_to_response('registration/search_page.html', {'getdata':getdata ,'getchoice':getchoice ,'searchcontacts': searchcontacts})    
        else:
            return HttpResponse('NO ITEMS FOUND ON THIS DATE')
在自定义模板中:-
<form method="POST" action="/testeruser/" class="form-horizontal"  name="searchform" enctype="multipart/form-data" >{% csrf_token %}
                <select name="userchoice" id="client_specification" class="span2"  required>                                                                    <option value='-1'>Select Your Choice </option>
                                                                <option value='0'>Biddings</option>
                                                                <option value='1'>Interviews</option>
                                                                <option value='2'>Jobs</option>
                </select>
               From: <input type="text"  class="input-xlarge" name="firstdate" id="search1" readonly="readonly" />  
                           To: <input type="text"  class="input-xlarge" name="seconddate" id="search2" readonly="readonly"/> </span>
                          <button class="btn btn-gebo" type="submit" name="asubmit" >Submit</button>
                              </form>       
    <!------------ PAGINATION---------------->
                        <div class="pagination"> 
                            <ul>    {% if searchcontacts.has_previous %}
                                <li><a href="?searchpage={{ searchcontacts.previous_page_number }}">PREVIOUS</a></li>
                {% endif %}
                {% if searchcontacts.has_next %}    
                                <li><a href="?searchpage={{ searchcontacts.next_page_number }}">NEXT</a></li>
                {% endif %} 
                            </ul>       
                        </div>
