Question

我试图在删除一个我不知道但无法正常工作的对象后重定向到页面。该对象将被删除，但不会重定向到任何页面，有人可以帮助我吗？如果您需要更多代码，可以询问我。谢谢！

删除产品的视图

@login_required() 
def delete_product(request, product_id):
    delete = get_object_or_404(Product, pk=product_id)
    form = NewPro(instance=delete)
    if request.method == 'POST':
        form = NewPro(request.POST, request.FILES, instance=delete)
        if form.is_valid():
            delete.delete()

            return redirect('store_details')
        else:
            form = NewPro(instance=delete)
    return render(request, "default/product_delete.html", {'form': form, 'delete': delete})

网址格式

from django.urls import path
from . import views
from stores.urls import views

app_name = 'stores'

urlpatterns = [
    path('<int:store_id>/store_details/', views.store_details, name='store_details'),

]

 urlpatterns = [
    path('<int:product_id>/product', views.product, name='products_details'),
    path('add_products/', views.pro, name='add_products'),
    path('', views.index_products, name='index_products'),
    path('<int:product_id>/detail_product', views.detail_product, name='detail_product'),
    path('<int:product_id>/edit_product', views.edit_product, name='edit_product'),
    path('<int:product_id>/delete_product', views.delete_product, name='delete_product')

]

该错误表明django无法解析视图store_details的路径。您可以使用reverse中的django.urls方法。

from django.urls import reverse

@login_required() 
def delete_product(request, product_id):
    delete = get_object_or_404(Product, pk=product_id)
    form = NewPro(instance=delete)
    if request.method == 'POST':
        # if this form is not valid we rander it again, so no need for else statement
        form = NewPro(request.POST, request.FILES, instance=delete)
        if form.is_valid():
            delete.delete()
            return redirect(reverse('stores:store_details'))
    # if it's not POST method render an empty form    
    else:
        form = NewPro()
    return render(request, "default/product_delete.html", {'form': form, 'delete': delete})

urls.py产品应用：

from django.urls import path
from . import views

app_name = 'product'

urlpatterns = [
    path('<int:product_id>/product', views.product, name='products_details'),
    path('add_products/', views.pro, name='add_products'),
    path('', views.index_products, name='index_products'),
    path('<int:product_id>/detail_product', views.detail_product, name='detail_product'),
    path('<int:product_id>/edit_product', views.edit_product, name='edit_product'),
    path('<int:product_id>/delete_product', views.delete_product, name='delete_product')
]

urls.py个商店应用：

from django.urls import path
from . import views

app_name = 'stores'

urlpatterns = [
    path('<int:store_id>/store_details/', views.store_details, name='store_details'),
]

随附的URLconf模块中的

app_name属性有助于反向解析URL

我希望这会有所帮助。

您没有为发布请求设置表单，请将else:移到选项卡上。

正确的语法：

@login_required() 
def delete_product(request, product_id):
    delete = get_object_or_404(Product, pk=product_id)
    form = NewPro(instance=delete)
    if request.method == 'POST':
        form = NewPro(request.POST, request.FILES, instance=delete)
        if form.is_valid():
            delete.delete()

            return redirect('store_details')
    else:
        form = NewPro(instance=delete)
    return render(request, "default/product_delete.html", {'form': form, 'delete': delete})

在Django中删除后如何重定向到页面？
