Django的 - AttributeError的在/藥方/「PrescriptionView」對象有沒有屬性「object_list中」

我使用AJAX後調用一組數據發送到我的觀點如下：Django的 - AttributeError的在/藥方/「PrescriptionView」對象有沒有屬性「object_list中」

class PrescriptionView(generic.ListView): 
    template_name = 'meds/prescription.html' 
    context_object_name = 'meds' 
    model = Medicament 

    def post(self, request, **kwargs): 
     selected_ids = request.POST.getlist('selected[]') 
     context = {'meds': Medicament.objects.filter(id__in=selected_ids)} 
     return super(PrescriptionView, self).render_to_response(context)

，你可以看到我的看法是一個ListView，我要的是要列出與IDS的那些對象從它Medicament.objects.filter(id__in=selected_ids)，但由於某種原因，我不斷收到以下錯誤selected_ids：

AttributeError at /prescription/ 
'PrescriptionView' object has no attribute 'object_list' 

Traceback:

Ajax調用：

jQuery(document).ready(function($) { 
     $("#continue").click(function() { 
      var selected = $("#meds").bootgrid("getSelectedRows"); 
      console.log(selected); 
      $.ajax({ 
       type: "POST", 
       url: "{% url 'meds:prescription' %}", 
       data: {selected:'selected' , csrfmiddlewaretoken: "{{ csrf_token }}"}, 
       success: function(result) { 
        $('#message').html("<h2>Contact Form Submitted!</h2>") 
       } 
      }); 
     }); 
    });

一次，在發送數據的陣列我已經使用以下模式：

var roles = data_selected(); 

$.ajax({ 
    type: 'POST', 
    url: '/get_roles/', 
    data: {'roles[]': roles}, 
    }); 
});

並且，在django的視圖，我

def get_roles(request): 
    roles = request.POST.getlist('roles[]') 
    ....

你可以分享你的ajax調用？我認爲發送數據時可能會混淆數據？

漢鼎POST請求：

def post(self, request, **kwargs): 
     selected_ids = request.POST.getlist('selected[]') 
     meds = self.get_queryset().filter(id__in=selected_ids) 
     return render(request, self.template_name, {'meds': meds })

我只是把它添加到後 – Meryem

望着文檔：https://docs.djangoproject.com/en/1.10/topics/class-based-views/generic -display /＃making-friendly-template-contexts，我沒有看到任何錯誤。但是，我想看看你是如何渲染你的列表。你正在循環模板中的「藥物」，對嗎？ –

我已經修改了上面的處理請求： 'def'post（self，request，** kwargs）： selected_ids = request.POST.getlist（'selected []'） meds = self.get_queryset （）.filter（id__in = selected_ids） return render（request，self.template_name，{'meds'：meds}）''' –
