未找到没有参数的“产品”反向。尝试了 1 种模式：['product\\/(?P<slug>[^/]+)\\/$']

Question

我正在尝试建立一个电子商务网站，但由于上面显示的错误，我可以继续。谢谢

url.py 文件

from django.urls import path
from .**views import ItemDetailView, HomeView, checkout

app_name = 'core'

urlpatterns =[
    path('', HomeView.as_view(), name='homepage'),
    path('checkout/', checkout, name='checkout'),
    path('product/<slug>/', ItemDetailView.as_view(), name='product')

views.py 文件

from django.shortcuts import render
from .models import Item
from django.views.generic import ListView, DetailView

class HomeView(ListView):
    model = Item
    template_name = "home-page.html"

class ItemDetailView(DetailView):
    model = Item
    template_name = "product-page.html"

def checkout(request):
    return render(request, 'checkout-page.html')

html模板

<a class="nav-link waves-effect" href="{% url 'core:product' %}" target="_blank">Products</a>

Answer 1

您还必须将 slug 传递给模板（在“home-page.html”中）

{% for product in object_list %}
<a class="nav-link waves-effect" href="{% url 'core:product' product.slug %}" 
target="_blank">{{ product.name }}</a>
{% endfor %}
