Django 2.2 實現 i18n 多語言國際化

在setting.py中設置：

#LANGUAGE_CODE = 'en-us'
LANGUAGE_CODE = 'zh-hans'

#翻譯文件所在目錄，須要手工建立
LOCALE_PATHS = (
    os.path.join(BASE_DIR, 'locale'),
)

TIME_ZONE = 'Asia/Shanghai'

USE_I18N = True

USE_L10N = True

在MIDDLEWARE 中加入'django.middleware.locale.LocaleMiddleware'：

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.locale.LocaleMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

在TEMPLATES添加'django.template.context_processors.i18n'

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates')],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.i18n',
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

 

mkdir -p locale

django-admin makemessages -l zh_Hans
django-admin compilemessages

 

或者

python3 django-admin makemessages -l zh_Hans
python3 django-admin compilemessages
 

運行後中英文切換
