for loop确实在view.py Django中工作？

Question

在view.py

中

Id = [2,3,4,5,6,7,8]

for w in Id:
    A = w
    Pending = pending(A)
    data = {     
        'Pending': Pending,

    }
    return render_to_response('dialer_campaign/campaign/list.html', data, context_instance=RequestContext(request))

def pending(campaign_id):

    A = Campaign_phonebook.objects.values_list('phonebook_id').filter(campaign_id = campaign_id)

    B = Contact.objects.filter(phonebook_id__in=A).count()
    C = Subscriber.objects.filter(campaign_id = campaign_id).exclude(status = 1).count()
    Result = B - C
    return Result

当我添加手动值而不是A时，它会给出结果，但现在我想通过for循环给出值，它不起作用。为什么？有人可以帮助我吗？

我想在模板中做更改吗？

先谢谢..

将您的数据对象放入列表并渲染到模板

参考以下代码

Id = [2,3,4,5,6,7,8]
pending_list = []
for w in Id:
    pending = pending(w)
    pending_list.append({'pending': pending})
    return render_to_response('dialer_campaign/campaign/list.html', pending_list, context_instance=RequestContext(request))

def pending(campaign_id):
    A = Campaign_phonebook.objects.values_list('phonebook_id').filter(campaign_id = campaign_id)
    B = Contact.objects.filter(phonebook_id__in=A).count()
    C = Subscriber.objects.filter(campaign_id = campaign_id).exclude(status = 1).count()
    Result = B - C
    return Result

在模板中使用pending_list。在pending_list列表中，您将获得所有待处理对象。
