django 处理和自定义异常

#首先在项目的urls.py，设置404和500

from  index import views

handler404=views.page_not_found

handler500 = views.page_error

然后定义index模块的views.py

def page_not_found(request,exception):

    return render(request,"404.html",status=404)

def page_error(request,exception):

    return render(request,"500.html",status=500)

settings.py 

DEBUG = Fasle 

以上自定义异常页面才生效
