自定义错误页面
常见的错误页面
- 400 bad request
- 403 HTTP Forbidden
- 404 page not found
- 500 server error
自定义错误页面
-
配置setting
DEBUG=True,Django会显示默认错误页面,我们要自定义,所以修改为DEBUG=False
如果这时启动项目会提示:CommandError: You must set settings.ALLOWED_HOSTS if DEBUG is False.
这是因为DEBUG=True,ALLOWED_HOSTS会验证['localhost','127.0.0.1','[::1]'],DEBUG=False,就必须填写ALLOWED_HOSTS.
指定ALLOWED_HOSTS=['*']就可以了 -
编写错误处理view
def page_not_found(request):
from django.shortcuts import render_to_response
response = render_to_response('404.html', {})
response.status_code = 404
return response
def page_error(request):
from django.shortcuts import render_to_response
response = render_to_response('500.html', {})
response.status_code = 500
return response
def method_not_allowed(request):
from django.shortcuts import render_to_response
response = render_to_response('403.html', {})
response.status_code = 403
return response
def bad_request(request):
from django.shortcuts import render_to_response
response = render_to_response('400.html', {})
response.status_code = 400
return response
- 配置url映射
handler400 = 'app_name.views.bad_request'
handler404 = 'app_name.views.page_not_found'
handler500 = 'app_name.views.page_error'
handler403 = 'app_name.views.method_not_allowed'
- 创建页面
在templates下建立相应的error.html
下面是我的公益404页面的设置
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
