1.直接覆盖内置视图
setting文件配置
DEBUG = False
ALLOWED_HOSTS = [*]
TEMPLATES = [
{
...
'DIRS': [os.path.join(BASE_DIR,'templates')],
...
}
templates/404.html
内容：
{{ request_path }}
404 NOT FOUND!!!
默认会调用内置视图
django.views.defaults.page_not_found(),
defaults.server_error(request, template_name='500.html')¶
defaults.bad_request(request, exception, template_name='400.html')
defaults.permission_denied(request, exception, template_name='403.html')
效果

2.重写
如把404.html模板写在templates/myapp下
父路由的url文件
from myapp import views
handler404 = views.page_not_found
handler404将会覆盖默认视图
myapp/404.html:
<body>
{{error}}
{{request_path}}
</body>
视图函数：
def page_not_found(request,exception):
return render(request, 'myapp/404.html',context={'error':'访问有误:页面不存在',"request_path":request.path}, status=404)
只要返回HttpResponseNotFound都可以
def not_found(request,exception):
from django.http import HttpResponseNotFound
return HttpResponseNotFound('<h1>Page not found</h1>')
3.自定义403页面
templates/403.html
from django.core.exceptions import PermissionDenied
def new_topic(request):
if not request.user.is_authenticated:
raise PermissionDenied
如果用户调用new_topic,将会出现自定义403页面
或者使用handler403自定义视图也可以
