Introduction

A Django reference book ** Create a screen for HTTP status code 403/404/500 ** There is a section, even if you * runserver * or get a 404 error The customized 404 screen was not displayed.

The reason is * DEBUG = True *

To create a screen for status code 403/404/500

templates * "directly under" the directory Just create a 403.html`` 404.html 500.html.

However, even if * runserver * is used as it is This screen is displayed. (Different from the screen I made ...)

At the bottom of the screen You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page. Is displayed.

Try translating with DeepL.

`This error is displayed because you have set DEBUG = True in your Django config file. If you change this to False, Django will display the standard 404 page. ``

If * DEBUG = True *, it looks like no good.

Try setting * DEBUG = False *

`settings.py`


DEBUG = True

Try * runserver *.

CommandError: You must set settings.ALLOWED_HOSTS if DEBUG is False. I got an error, so I'll fix it.

`settings.py`


DEBUG = True

ALLOWED_HOSTS = ['127.0.0.1']

Add ʻALLOWED_HOSTS = ['127.0.0.1']` Try * runserver *.

The customized 404 screen was displayed successfully.

`404.html`
