Django - 如何将值从 <a href> 传递给视图

Question

我在模板中有一个类别下拉列表。我不想对其进行硬编码并为每个类别编写单独的列表视图。那么有没有办法将值传递<a href="">给视图？我想self.request.GET.get('category search')永远不会奏效，因为没有<form method="get">标签。因此它总是None由于return queryset.none()声明而返回。主页.html：<div class="dropdown-menu" aria-labelledby="navbarDropdown">    {% if all_categories %}        {% for category in all_categories %}            <a name="category search" href="{% url 'book:category_search' category.id %}"> {{ category }} </a>        {% endfor %}    {% endif %}</div>book.urls.py：urlpatterns = [    .........    path('categories/<int:pk>', views.CategorySearchView.as_view(), name='category_search'),]book.views.py：class CategorySearchView(generic.ListView):    template_name = 'book/search.html'    model = Book    context_object_name = 'book_list'    paginate_by = 100    def get_queryset(self):        queryset = super().get_queryset()        search = self.request.GET.get('category search')        if search:            queryset = Book.objects.filter(categories__id=search)            return queryset        else:            return queryset.none()
