在Django的url中设置GET参数

Question

我想创建一个带有各种可选过滤器的列表视图。我的网址应该是这个样子：

shop/category_6/?manufacturer_id=3 

而且它工作得很好，当我把这个网址只是在浏览器的形式。但是当我尝试将这个选项添加到模板时，它给了我NoReverseMatch。我的模板：

{% for manufacturer in manufacturer_list %} 
    <p><a href = "{% url 'shop:item_list' category_id=category.id manufacturer_id=manufacturer.0 %}">{{manufacturer.1}}</a></p> 
{% endfor %} 

这是我的观点：

class ItemListView(ListView): 
    model = Item 
    context_object_name = 'item_list' 
    template_name = 'shop/item_list.html' 

def get_queryset(self, **kwargs): 
    full_item_list=Item.objects.all() 
    queryset=full_item_list.filter(category__id=int(self.kwargs['category_id'])) 
    manufacturer_id = self.request.GET.get('manufacturer_id') 
    if manufacturer_id: 
     queryset=queryset.filter(manufacturer__id=int(manufacturer_id)) 
    return queryset 

def get_context_data(self, **kwargs): 
    context = super(ItemListView, self).get_context_data(**kwargs) 
    context['category']=get_object_or_404(Category, pk=self.kwargs['category_id']) 
    context['manufacturer_list'] = self.get_queryset(**kwargs).values_list('manufacturer__id', 'manufacturer__name').distinct().order_by('manufacturer__name') 
    return context 

什么是我的错？

没有配置GET参数...可能是店/ category_6 /? MANUFACTURER_ID = 3

<a href = "{% url 'shop:item_list' category_id=category.id %}?manufacturer_id={{ manufacturer.0 }}">{{manufacturer.1 }}</a>
