无法在Django中切换语言环境

Question

我有一个文件locale/es/LC_MESSAGES/django.mo（和.po），运行了makemessages和compilemessages。所有消息都已经翻译完成。

在settings.py中有：

USE_I18N = True
LANGUAGE_CODE = 'es'

为什么Django执意从英文.po文件中读取字符串？这其中一定有一些需要注意的地方...谢谢。

编辑 当LocaleMiddleware处于活动状态时，才会出现这种情况。

根据Django文档，LocaleMiddleware尝试通过以下算法确定用户的语言偏好：

http://docs.djangoproject.com/en/dev/topics/i18n/#id2

LocaleMiddleware 尝试通过以下算法来确定用户的语言偏好：

* First, it looks for a django_language key in the current user's session.

* Failing that, it looks for a cookie. 

[...]

*Failing that, it looks at the Accept-Language HTTP header. This header is sent by your browser and tells the server which language(s) you prefer, in order by priority. Django > tries each language in the header  until it finds one with available translations.

* Failing that, it uses the global LANGUAGE_CODE setting.

如果只需要一种语言' es'，你可以禁用中间件。如果你确实需要启用LocaleMiddleware，请尝试使用此方法覆盖来自客户端浏览器的标头：http://www.djangosnippets.org/snippets/218/:

enter code here

class ForceDefaultLanguageMiddleware(object):
    """
    Ignore Accept-Language HTTP headers

    This will force the I18N machinery to always choose settings.LANGUAGE_CODE
    as the default initial language, unless another one is set via sessions or cookies

    Should be installed *before* any middleware that checks    request.META['HTTP_ACCEPT_LANGUAGE'],
    namely django.middleware.locale.LocaleMiddleware
    """
    def process_request(self, request):
        if request.META.has_key('HTTP_ACCEPT_LANGUAGE'):
            del request.META['HTTP_ACCEPT_LANGUAGE']

对于使用Python 3.X的用户，if request.META.has_key('HTTP_ACCEPT_LANGUAGE'): 需要改为 if 'HTTP_ACCEPT_LANGUAGE' in request.META:。 - reinaldoluckman

我在我的设置中使用这个：

TIME_ZONE = 'Europe/Paris'
LANGUAGE_CODE = 'fr-FR'
SITE_ID = 1
USE_I18N = True

所以你应该使用类似于“es-ES”的东西
