收到“找不到页面 (404) 没有产品与给定查询匹配。”错误

问题描述 投票：0回答：1

从数据库中删除所有产品后，我开始收到此错误（我这样做是因为它只是用于测试的虚拟数据）。当我运行服务器并转到本地主机时，我看到这个错误

该错误指出，尽管产品未在主页上调用，但该问题是在“home.views.index”中提出的。我觉得我的应用程序正在寻找产品，但在找不到产品时崩溃了。

这是我的应用程序 urls.py 的代码

from django.contrib import admin
from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
     path('', include('home.urls')),
     path('admin/', admin.site.urls),
     path('products/', include('products.urls')),
     path('checkout/', include('checkout.urls')),
     path('bag/', include('bag.urls')),
     path('contact/', include('contact.urls')),
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

这是我的产品/urls.py

from django.urls import path
from . import views
urlpatterns = [
     path('', views.all_products, name='products'),
     path('<int:product_id>/', views.product_detail, name='product_detail'),
]

这是 products/views.py 的代码

from django.shortcuts import render
from .models import Product
def all_products(request):
    products = Product.objects.all()

    context = {
         'products': products,
 }

return render(request, "products/products.html", context )

def product_detail(request, product_id):
     product = get_object_or_404(Product, pk=product_id)

     context = {
        'product': product,
    }

return render(request, 'products/product_detail.html', context)

这是 home/urls.py 的代码

from django.urls import path
from . import views

urlpatterns = [
    path('', views.index, name='home')
]

这是 home/views.py 的代码

from django.shortcuts import render

def index(request):
    return render(request, 'home/index.html')

这里是index.html

你应该最后添加 home.urls

或者，

在 home.urls 中添加其他路径

urlpatterns = [
     # path('', include('home.urls')),
     path('admin/', admin.site.urls),
     path('products/', include('products.urls')),
     path('checkout/', include('checkout.urls')),
     path('bag/', include('bag.urls')),
     path('contact/', include('contact.urls')),
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

**urlpatterns.append(path('', include('home.urls')))**
