如何使用url中的参数从django中的数据库中获取数据？

Question

** URl：**

path('products_filter/', views.products_filter, name='products_filter'),

**查看:**

def products_filter(request):
    product = request.GET.get('product')
    selling = request.GET.get('selling')
    
    products = Product.objects.filter(selling='best_seller')

    return render(request, 'product/products.html', {'products':products})

**模板：**

<a href="/product/products_filter?product={{'carpet'|urlencode}}&selling={{'best_seller'|urlencode}}">

Answer 1

将要从url中检索的参数添加到您的url中，并确保模板中的url添加了这些参数。例如：

urls.py：

path('products_filter/<str:product>/<str:selling>/', views.products_filter, name='products_filter'),

模板：

<a href="{% url 'products_filter' product=carpet|urlencode selling=best_seller|urlencode %}">
