Question

我确信我错误地说了这个问题，但是这里...... 我有一个在conference_list.html中显示的会议列表以及与会者数量。。他们的头衔显得很好......然而，每次会议的与会者人数都相同。

Conference 1        Attendees 2
Conference 2        Attendees 2
Conference 3        Attendees 2 
Conference 4        Attendees 2

第4次会议是唯一有2位与会者的会议。其他人有不同的金额。

Views.py：

@login_required
def conference_list(request):
    try:
        session_notification = request.session['notification']
        del(request.session['notification'])
    except:
        session_notification = None

    PAGE_SIZE = 20#number of conferences per page
    page = int(request.GET.get('page', 1))
    upper_bound = page * PAGE_SIZE - 1
    lower_bound = (page - 1) * PAGE_SIZE

    context = base_context(request)
    network = context['network']

    conferences = Conference.objects.all()
    second = []
    result = []
    counter = 0

    for conference in conferences:
        is_attending = False
        if counter < lower_bound or counter > upper_bound:
            counter += 1
            result.append(None)
            continue
        result_item = {}
        result_item['conference'] = conference
        result.append(result_item)
        counter += 1

        attendees = conference.investors.all()
        count = attendees.count()
        if request.user in attendees:
            is_attending = True

        context['attendees'] = attendees
        context['is_attending'] = is_attending
        context['count'] = count

    context['current'] = 'conferences'
    context['conferences'] = result

    return render_to_response('conference_list.html', context, context_instance=RequestContext(request))

模板：

{% for conference in conferences %}
     <p>{{ conference.conference.name }}</p><span>{{ count }}</span>
{% endfor %}

为什么会这样？为什么我不能显示适当的金额？

您的count变量只保存最后一个值，因为您只是在视图中循环的每次迭代时覆盖它。试试result_item['conferences']['count'] = count并在其后移动result.append(result_item)行。相应地调整模板。

Python在循环列表中显示相同的值。
