Django应用过滤器重新载入数据表

所以我有几个过滤器，用户可以申请更改表中显示的信息。我有一个Ajax调用被触发每当用户点击这些过滤器的一个：Django应用过滤器重新载入数据表

 $.ajax({ 
      url: '/fund_monitor/fund_directory', 
      type: 'GET', 
      data:JSON.stringify({ 
       filter_dict: filter_dict 
      }), 
      success: function (data) { 
      } 
     });

很简单的东西。接下来我的Class Based View将为此服务Ajax Call。

def get(self, request, *args, **kwargs): 
    filtered_ids = [] 
    if request.is_ajax(): 
     #filter_dict = request.GET.getlist('filter_dict') 
     request_data = json.dumps(request.GET) 
     request_data = json.loads(request_data) 
     for each in request_data: 
      each = json.loads(each) # Just for parsing 
      for key, value in each['filter_dict'].items(): 
       if key == 'Structure': 
        objects = Fund.objects.filter(structure__in=value).values('fund_account_id').distinct() 
        for fund_account_id in objects: 
         filtered_ids.append(fund_account_id['fund_account_id']) 
       elif key == 'Fund Class': 
        objects = Fund.objects.filter(fund_class__in=value).values('fund_account_id').distinct() 
        for fund_account_id in objects: 
         filtered_ids.append(fund_account_id['fund_account_id']) 
       elif key == 'Designated Broker': 
        objects = Fund.objects.filter(designated_broker__in=value).values('fund_account_id').distinct() 
        for fund_account_id in objects: 
         filtered_ids.append(fund_account_id['fund_account_id']) 

     filtered_ids = set(filtered_ids) 
     context = self.get_context_data(filtered_ids, **kwargs) 
     self.template_name = 'fund_monitor/fundaccount_table_list.html' 
     return self.render_to_response(context) 
    context = self.get_context_data(**kwargs) 
    return self.render_to_response(context)

所以我收集毕竟，我要显示在表中ids，我把它传递给get_context_data函数，它接受所有这些ids并求出基于ids所需的信息。

def get_context_data(self, filtered_ids=None, **kwargs): 
    context = super(__class__, self).get_context_data(**kwargs) 
    context['nbar'] = 'fund_monitor' 
    context['sbar'] = 'fundaccount_list' 
    context['transmission'] = 3 

    if filtered_ids: 
     context['fundaccount_list'] = self.model.objects.filter(id__in=filtered_ids) 
    else: 
     context['fundaccount_list'] = self.model.objects.all() 
    url_dict = defaultdict(list) 
    for fund in context['fundaccount_list']: 
     end_date = str(NAV.objects.filter(fund= fund.id, transmission=3).values('valuation_period_end_date').order_by('-valuation_period_end_date')[0]['valuation_period_end_date']) 
     start_date = str(NAV.objects.filter(fund= fund.id, transmission=3).values('valuation_period_end_date').order_by('-valuation_period_end_date')[1]['valuation_period_end_date']) 

     url_dict[fund.account_description].extend([fund.id,context['transmission'], 
                start_date, end_date]) 
    context['obj_items'] = dict(url_dict) 
    return context

所以后返回背景下，在get功能，该行：

self.template_name = 'fund_monitor/fundaccount_table_list.html' 
return self.render_to_response(context)

应与修改TEMPLATE_NAME运行。这个template_name基本上只包含表格HTML。基本上，我只希望表刷新自己，而不是整个页面...但是，虽然由于筛选器context正在更新表不重新加载。有任何想法吗？

简单的解决方案：

$.ajax({ 
     url: '/fund_monitor/fund_directory', 
     type: 'GET', 
     data:JSON.stringify({ 
      filter_dict: filter_dict 
     }), 
     success: function (data) { 
      $("#myTable").html(data); // Add this line to your based on your table div 
     } 
    });
