问题描述
在django模板中是否有一些gettin语言代码的全局变量，或者至少通过视图传递它？
如下： {{LANG}} 应该产生en，例如..
当人们使用 request.LANGUAGE_CODE 。
Is there's some global variable for gettin' language code in django template or atleast passing it through view?something like: {{ LANG }} should produce "en" for example..I really not comfortable when people using request.LANGUAGE_CODE.
详细解释将不胜感激=）
Detailed explanation would be appreciated =)
推荐答案
不存在，您需要编写一个。以下是您如何做到这一点。
If it didn't already exist, you would need to write a template context processor. Here's how you'd do that.
将此放在某个地方：
def lang_context_processor(request):
return {'LANG': request.LANGUAGE_CODE}
然后，添加设置。这样做：
And then, add a reference to it the TEMPLATE_CONTEXT_PROCESSORS setting. Something like this:
from django.conf import global_settings
TEMPLATE_CONTEXT_PROCESSORS = global_settings.TEMPLATE_CONTEXT_PROCESSORS + (
'myproject.myapp.templatecontext.lang_context_processor',
)
（我推荐添加到全局设置，因为这意味着当一个新的上下文处理器添加到默认值时，您不会意外中断事件。）
(I recommend adding to the global setting because it means you don't break things accidentally when a new context processor is added to the defaults.)
但是，它确实存在，因为内置模板上下文处理器。您可以使用 LANGUAGE_CODE 访问它。
However, it does exist, as the inbuilt template context processor django.core.context_processors.i18n. You can access it as LANGUAGE_CODE.
纯粹为了感兴趣，这里是该功能的定义：
Purely for interest, here's the definition of that function:
def i18n(request):
from django.utils import translation
context_extras = {}
context_extras['LANGUAGES'] = settings.LANGUAGES
context_extras['LANGUAGE_CODE'] = translation.get_language()
context_extras['LANGUAGE_BIDI'] = translation.get_language_bidi()
return context_extras
确保您使用的是 RequestContext 用于您的模板呈现，而不是一个简单的上下文，否则它将无法正常工作。
Make sure that you're using a RequestContext for your template rendering, not a plain Context, or it won't work.
