Django自定义404,500页面

1,462 views

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’)],

# SECURITY WARNING: don't run with debug turned on in production!

DEBUG = False

ALLOWED_HOSTS = ['localhost','www.example.com', '127.0.0.1']

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.新建一个views.py

from django.http import HttpResponse

from django.shortcuts import render_to_response

from django.views.decorators.csrf import csrf_exempt

@csrf_exempt

def hello(request):

    return HttpResponse('Hello World!')

@csrf_exempt

def page_not_found(request):

    return render_to_response('404.html')

@csrf_exempt

def page_error(request):

    return render_to_response('500.html')

5.修改urls.py,代码如下


from django.conf.urls import url

from django.contrib import admin

import HelloWorld.views as view

urlpatterns = [

    url(r'^admin/', admin.site.urls),

    url(r'^test$', view.hello),

]

handler404 = view.page_not_found

handler500 = view.page_error

重新编译,重启uwsgi,输入localhost/HelloWorld/test,显示’Hello World!’,输入其它地址会显示404.html内容,如果出错则显示500.html内容。
