Python 2.7 分页时未进行筛选

我在视图中添加了分页。分页工作正常，但当我筛选数据并导航到下一页时，它不会对筛选的数据进行分页，而是转到下一页，而不会进行筛选

视图

 class CashFilter(django_filters.FilterSet):

    class Meta:
        model = NSE_Cash_Trades
        fields = {'dates':['lte','gte'],'order_entry_time':['lte','gte'],'trade_entry_time':['lte','gte'],'trade_modified_time':['lte','gte'],'symbol':['exact'],'client_ac':['exact'],'buys_sell_indicator':['exact'],'participant_code':['exact'],'trade_qty':['exact'],'ctcls_id':['exact'],'order_num':['exact'],'trade_no':['exact']}


 def NSE_Cash_Trades_Search(request):
      f =CashFilter(request.GET, queryset=NSE_Cash_Trades.objects.all())
      paginator = Paginator(f.qs,100)
      page = request.GET.get('page')
      try:
         leads = paginator.page(page)
      except PageNotAnInteger:

         leads = paginator.page(1)
      except EmptyPage:

         leads = paginator.page(paginator.num_pages)

      t = loader.get_template('admin/newftp/search2.html')
      ctx=RequestContext(request,{'filter':f,"leads":leads,})
        return HttpResponse(t.render(ctx))`

有人能帮我找到解决办法吗

这里您要做的是将请求值传递给URL，您必须在模板中进行如下更改

</table>
  <span class="step-links">
    {% if leads.has_previous %}
    <a href="?page={{ leads.previous_page_number }}&dates__lte={{request.GET.dates__lte}}&dates__gte={{request.GET.dates__gte}}&order_entry_time__lte={{request.GET.order_entry_time__lte}}&order_entry_time__gte={{request.GET.order_entry_time__gte}}&trade_entry_time__te={{request.GET.trade_entry_time__lte}}&trade_entry_time__gte={{request.GET.trade_entry_time__gte}}&trade_modified_time__lte={{request.GET.trade_modified_time__lte}}&trade_modified_time__gte={{request.GET.trade_modified_time__gte}}&symbol={{request.GET.symbol}}&client_ac={{request.GET.client_ac}}&buys_sell_indicator={{request.GET.buys_sell_indicator}}&participant_code={{request.GET.participant_code}}&trade_qty={{request.GET.trade_qty}}&ctcls_id={{request.GET.ctcls_id}}&order_num={{request.GET.order_num}}&trade_no={{request.GET.trade_no}}">previous</a>
    {% endif %}

{%if leads.has_previous%}
{%endif%}

---

对href next进行相同的更改请在模板中进行下面给出的更改，下面的代码将允许分页获得筛选值，因此它将通过筛选值进行分页。对下一个进行相同的更改

</table>
  <span class="step-links">
    {% if leads.has_previous %}
    <a href="?page={{ leads.previous_page_number }}&dates__lte={{request.GET.dates__lte}}&dates__gte={{request.GET.dates__gte}}&order_entry_time__lte={{request.GET.order_entry_time__lte}}&order_entry_time__gte={{request.GET.order_entry_time__gte}}&trade_entry_time__te={{request.GET.trade_entry_time__lte}}&trade_entry_time__gte={{request.GET.trade_entry_time__gte}}&trade_modified_time__lte={{request.GET.trade_modified_time__lte}}&trade_modified_time__gte={{request.GET.trade_modified_time__gte}}&symbol={{request.GET.symbol}}&client_ac={{request.GET.client_ac}}&buys_sell_indicator={{request.GET.buys_sell_indicator}}&participant_code={{request.GET.participant_code}}&trade_qty={{request.GET.trade_qty}}&ctcls_id={{request.GET.ctcls_id}}&order_num={{request.GET.order_num}}&trade_no={{request.GET.trade_no}}">previous</a>

{%if leads.has_previous%}

我也有同样的问题，我想我们必须将查询集vlaue传递给模板中的href。我明白你的意思，我实现了，但错误仍然存在@Krish
