Django下定义404页面跳转方法如下

1.创建一个项目

django-admin.py startproject HelloWorld

2.进入HelloWorld项目,在manage.py的同一级目录，创建templates目录，并在templates目录下新建404.html，500.html两个文件。

3.修改settings.py

（1.）DEBUG修改为False,（2.）ALLOWED_HOSTS添加指定域名或者IP，（3.）指定模板路径 ‘DIRS' : [os.path.join(BASE_DIR,‘templates')],

DEBUG = False
ALLOWED_HOSTS = ['localhost','127.0.0.1']
# Application definition
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'sign', #添加sign 应用
]
MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    # 'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]
ROOT_URLCONF = 'autotest.urls'
TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates')],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

4.修改views.py

from django.http import HttpResponse,HttpResponseRedirect
from django.views.decorators.csrf import csrf_exempt
from django.shortcuts import render
from django.shortcuts import render_to_response

5.修改urls.py，代码如下

添加：

handler404=views.page_not_found
handler500=views.page_error

如下

from django.conf.urls import url
from django.contrib import admin
from sign import views #导入sign 应用views 文件
urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^index/$', views.index), #添加index/路径配置
    url(r'^create_action/$', views.create_action),
    url(r'^creating/$', views.creating),
    url(r'^home/$', views.home),
    url(r'^buycrouse/$', views.buycrouse),
    url(r'^tologin/$', views.tologin),
    url(r'^login_action/$', views.login_action),
    url(r'^manage/$', views.manage),
    url(r'^$',views.home),
    url(r'^accounts/login/$', views.tologin),
]
handler404=views.page_not_found
handler500=views.page_error
