Django的分页程序不提供

上的内容我使用Django分页程序来打破我的搜索结果Django的分页程序不提供

from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger

在我看来几页，我进行基于输出形式的搜索

@login_required 
def payment_range_list(request): 
    #import pdb; pdb.set_trace() 

    title = 'payment list' 
    #import pdb; pdb.set_trace() 
    if request.method == "POST": 
     form = PaymentRangeForm(request.POST) 
     #import pdb; pdb.set_trace() 

     if form.is_valid(): 
      start_date = form.cleaned_data['start_date'] 
      end_date = form.cleaned_data['end_date'] 
      building = form.cleaned_data['building'] 

      payment_list = LeasePaymentFilter(request.GET, queryset=LeasePayment.objects.filter(payment_date__range=[start_date, end_date],lease__unit__building = building)) 
      paginator = Paginator(payment_list, 25) # Show 25 contacts per page 

      page = request.GET.get('page') 
      try: 
       payment_page = paginator.page(page) 
      except PageNotAnInteger: 

       payment_page = paginator.page(1) 
      except EmptyPage: 

       payment_page = paginator.page(paginator.num_pages) 
     else: 
      payment_list = None 
      payment_page = None 
      start_date = None 
      end_date = None 
      building = None 



    else: 
     payment_list = None 
     payment_page = None 
     start_date = None 
     end_date = None 
     building = None 

     #form = PaymentRangeForm() 
     form = PaymentRangeForm(initial = {'building': 0 }) 



    return render(request,'payment/payment_range.html', {'form':form, 'payment': payment_list,'page_payment':payment_page, 'start_date':start_date, 'end_date':end_date, 'building':building })

在页面的顶部，我有一个表单用于搜索，第二部分用于显示结果。

{% extends "rent_base.html" %} 

{% load crispy_forms_tags %} 
    {% block title %} 
    Lease List 
    {% endblock title %} 
{% block content %}

     </tr> 



      {% for payment in page_payment %} 
     <tr> 
      <td> <a href="{% url 'lease_payment_details' pk=payment.lease.id %}" class="btn btn-default"> {{ payment.id }}</a></td> 
      <td> {{ payment.get_payment_type_display }}</td>

           {% endif %} 
      </td> 

      <td> {{ payment.lease }}</td> 
      <td> {{ payment.lease.unit.number }}</td> 
      <td> {{ payment.lease.unit.building.name }}</td> 
      <td> {{ payment.leaseterm }}</td> 
      <td> {{ payment.payment_date }}</td> 
      <td> {{ payment.get_method_display }}</td> 
     </tr> 
      {% endfor %} 
</table> 
<div class="pagination"> 
    <span class="step-links"> 
     {% if page_payment.has_previous %} 
      <a href="?page={{ page_payment.previous_page_number }}">previous</a> 
     {% endif %} 

     <span class="current"> 
      Page {{ page_payment.number }} of {{ page_payment.paginator.num_pages }}. 
     </span> 

     {% if page_payment.has_next %} 
      <a href="?page={{ page_payment.next_page_number }}">next</a> 
     {% endif %} 
    </span> 
</div> 


    </div> 
</div></div> 
{% endblock content %}

我的问题是，当我的搜索返回的结果超过1页的数量，我点击下一页。接下来的页面总是空的。

任何反馈，我的问题是？

问题是您的serch表单是POST。所以当你点击下一步按钮时你发送GET请求并if request.method == "POST":部分你查看不会被触发。我建议你改变serch主页形式GET：

<form method="GET" action=""> 
    <input type="text" name="q" placeholder="Search" value="{{ request.GET.q }}"> 
    <input type="submit" value="Search"> 
</form>

，并更改下一个按钮这样的：

{% if payment.has_next %} 
     <a href="?page={{ payment.next_page_number}}{% if request.GET.q %}&q={{ request.GET.q }}{% endif %}">next</a> 
{% endif %}

这将节省搜索值在地址栏中你移动到下一个页面后还是一样。
