我在模板中有一個類別下拉列表。我不想對其進行硬編碼并為每個類別編寫單獨的列表視圖。那么有沒有辦法將值傳遞<a href="">給視圖？我想self.request.GET.get('category search')永遠不會奏效，因為沒有<form method="get">標簽。因此它總是None由于return queryset.none()聲明而返回。主頁.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()
