django rest 框架翻译对我不起作用

Question

I tried django rest framework internationalization.

doc drf internationalization

From official drf documentation a set this code in settings.py

from django.utils.translation import gettext_lazy as _

MIDDLEWARE = [
    ...
    'django.middleware.locale.LocaleMiddleware'
]

LANGUAGE_CODE = "it"

LANGUAGES = (
    ('en', _('English')),
    ('it', _('Italian')),
    ('fr', _('French')),
    ('es', _('Spanish')),
)

TIME_ZONE = 'UTC'

USE_I18N = True

but when I try out POST api rest

curl -X 'POST' \
  'http://172.18.0.1:7000/appjud/api/v1/reset-password/' \
  -H 'accept: application/json' \
  -H 'Authorization: Token 014cb7982f31767a8ce07c9f216653d4674baeaf' \
  -H 'Content-Type: application/json' \
  -d '{
  "new_password": "",
  "confirm_password": ""
}'

Response body
[
  {
    "newpassword": [
      "This field is required."
    ],
    "confirmpassword": [
      "This field is required."
    ]
  }
]

Response headers
allow: POST,OPTIONS  
content-language: en  
content-length: 91  
content-type: application/json  
cross-origin-opener-policy: same-origin  
date: Sat,03 Dec 2022 16:14:16 GMT  
referrer-policy: same-origin  
server: WSGIServer/0.2 CPython/3.9.15  
vary: Accept,Accept-Language,Origin  
x-content-type-options: nosniff  
x-frame-options: DENY

UPDATE

MIDDLEWARE = [
    'corsheaders.middleware.CorsMiddleware',
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.locale.LocaleMiddleware',
    'django.middleware.common.CommonMiddleware',
     ...
]

As we can see it print "This field is required." but I would like "Questo campo è obbligatorio." What Does I miss in config settings.py file?

Looks like you added LocaleMiddleware to the end of middlewares list. But order is matter here. From the docs :

Because middleware order matters, follow these guidelines:

Make sure it's one of the first middleware installed. It should come after SessionMiddleware, because LocaleMiddleware makes use of session data. And it should come before CommonMiddleware because CommonMiddleware needs an activated language in order to resolve the requested URL. If you use CacheMiddleware, put LocaleMiddleware after it.

Try to change order according to this note.
