在django视图中设置语言

Question

背景: 当支付服务在幕后追回付款结果时调用该视图 - 之后我需要以正确的语言发送电子邮件以确认付款等等.我可以在支付服务器的请求中获取语言代码,并希望将其与Django的i18n系统一起使用,以确定将我的电子邮件发送到哪种语言.

所以我需要在视图中设置我的django应用程序的语言.然后一次性完成我的模板渲染和电子邮件.

设置request.session['django_language'] = lang仅在我测试时影响下一个视图.

还有其他办法吗？

干杯,

家伙

Answer 1

引用Django的Locale Middleware(django.middleware.locale.LocaleMiddleware)中的部分:

from django.utils import translation

class LocaleMiddleware(object):
    """
    This is a very simple middleware that parses a request
    and decides what translation object to install in the current
    thread context. This allows pages to be dynamically
    translated to the language the user desires (if the language
    is available, of course).
    """

    def process_request(self, request):
        language = translation.get_language_from_request(request)
        translation.activate(language)
        request.LANGUAGE_CODE = translation.get_language()

这translation.activate(language)是重要的一点.

一定要在process_response中添加deactivate,否则你会遇到不同线程的问题.

from django.utils import translation

class LocaleMiddleware(object):
    """
    This is a very simple middleware that parses a request
    and decides what translation object to install in the current
    thread context. This allows pages to be dynamically
    translated to the language the user desires (if the language
    is available, of course).
    """

    def process_request(self, request):
        language = translation.get_language_from_request(request)
        translation.activate(language)
        request.LANGUAGE_CODE = translation.get_language()

    def process_response(self, request, response):
        translation.deactivate()
        return response

如果只是想出于某种原因获取某种语言的翻译字符串，您可以使用override如下装饰器：

from django.utils import translation
from django.utils.translation import ugettext as _

with translation.override(language):
    welcome = _('welcome')

Answer 4

您可以考虑将语言存储在用户模型中并使用此自定义中间件django-user-language-middleware。

这样您就可以通过查看字段中所选的语言来轻松翻译您的 Django 应用程序user.language，并且您始终可以了解任何用户的语言偏好。

用法：

1. 将语言字段添加到您的用户模型中：

   class User(auth_base.AbstractBaseUser, auth.PermissionsMixin):
       # ...
       language = models.CharField(max_length=10,
                                   choices=settings.LANGUAGES,
                                   default=settings.LANGUAGE_CODE)
   

2. 从 pip 安装中间件：

   pip install django-user-language-middleware

3. 将其添加到设置中的中间件类列表中以监听请求：

   MIDDLEWARE = [  # Or MIDDLEWARE_CLASSES on Django < 1.10
       ...
       'user_language_middleware.UserLanguageMiddleware',
       ...
   ]
   

我希望这可以帮助人们将来解决这个问题。
