我正在尝试获取每个侵权者的侵权总数。计数器未递增。（{{ a| add：“1”}}）它输出1 1 1而不是总共3。请协助。
{% for infringer in page_obj %}
<tr>
<td>{{infringer.id}}</td>
<td>{{infringer.created|date:"d M, Y"}}</td>
<td>{{infringer.name}}</td>
<td>{{infringer.brand_name}}</td>
<td>{{infringer.status}}</td>
<td>
{% with a=0 %}
{% for i in inc %}
{% if infringer.id == i.infringer.id %}
{{ a|add:"1" }}
{% endif %}
{% endfor %}
{% endwith %}views.py
@login_required(login_url='login')
def infringerlist(request):
q = request.GET.get('q') if request.GET.get('q') != None else ''
ings= Infringer.objects.filter(Q(created__icontains=q) | Q(id__icontains=q) |
Q(status__name__icontains=q) |
Q(brand_name__icontains=q) | Q(name__icontains=q),
customer=request.user.customer,)
paginator = Paginator(ings, 10)
page_number = request.GET.get('page')
page_obj = paginator.get_page(page_number)
inc = Infringement.objects.filter(customer=request.user.customer)
context= {'page_obj': page_obj, 'inc': inc}
return render(request,'base/infringers_list.html', context)

模板 * 不 * 应该有业务逻辑。它们也不应该改变状态。它们应该只是 * 呈现 * 数据。
您可以计算入侵的数量，然后将其传递给上下文：
并使用
{{ infrigments }}对其进行渲染。
