Django实现自定义404，500页面教程
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。
