问题描述
我想根据我的settings.py中定义的语言，将html标记中的lang属性设置为当前语言环境的语言.我不使用LocaleMiddleware，用户无法选择语言.
I want to set the lang attribute in my html tag to the current locale's language based on the language defined in my settings.py. I don't use the LocaleMiddleware and the user can not choose the language.
(我在同一页面上具有不同的域.如果某人希望以其他语言查看该网站，则用户必须转到其他网站)
(I have different domain's for the same page. If someone want's to see the website in a different language, the user has to go to a different website )
settings.py
LANGUAGE_CODE = 'pl-PL'
USE_I18N = True
USE_L10N = True
LANGUAGES = [
('en', 'English'),
('de', 'German'),
('pl', 'Polish'),
('ru', 'Russian'),
('uk', 'Ukrainian'),
]
MIDDLEWARE = [
'corsheaders.middleware.CorsMiddleware',
'pipeline.middleware.MinifyHTMLMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
'django.contrib.redirects.middleware.RedirectFallbackMiddleware',
]
Django版本
Django == 2.0.9
Django==2.0.9
模板
{% load i18n %}
{% get_current_language as LANGUAGE_CODE %}
{% get_language_info for LANGUAGE_CODE as lang %}
<!DOCTYPE html>
<html lang="{{ LANGUAGE_CODE }}">
输出
如果我在没有交互的情况下刷新页面，有时会得到:
If I refresh the page without interacting I got sometimes:
- pl
- pl-pl
- pl-PL
为什么会这样?
推荐答案
您可以尝试使用{{ lang.code }}仅获取pl部分(取决于语言).
You can try using {{ lang.code }} to get only pl part (it depends on language).
在这种情况下，Django从 Accept-Language (HTTP语言)标头获取用户语言首选项，该标头通常包含多个具有优先级的语言代码.
In this case Django gets user language preference from Accept-Language HTTP header, which usually contains several language codes, with priority.
它可能包含一种基本语言的多种语言代码，具体取决于您的系统区域设置，浏览器设置等；即 pl-PL，pl-pl，pl; q = 0.7 ，其中 q 是优先级.
It may contain multiple language-codes for one base language, depending on your system locale, browser settings, etc; i.e. pl-PL,pl-pl,pl;q=0.7 where q is priority.
Django解析标头并根据优先级对语言代码进行排序.由于多个代码的优先级相同-每个请求的结果将以不同的顺序出现，并且将使用第一个.
Django parses header and sorts language codes based on priority. Since priority is the same for several codes - they will appear in different order in the result for each request and the first one will be used.
