如何使用 django.views.i18n.set_language() 函数？
我在 Django 站点中阅读了教程 /a> 但我不明白如何使用 set_language() 函数。例如，我有一个演示如下：
index.html
{% trans "Hello World." %}
<form action="/i18n/setlang/" method="post">
{% csrf_token %}
<input name="next" type="hidden" value="/next/page/" />
<select name="language">
{% get_language_info_list for LANGUAGES as languages %}
{% for language in languages %}
<option value="{{ language.code }}">{{ language.name_local }} ({{ language.code}})</option>
{% endfor %}
</select>
<input type="submit" value="Go" />
</form>
urls.py
urlpatterns = patterns('',
(r'^i18n/', include('django.conf.urls.i18n')),
)
views.py
What need I write to display the languages, which were chosen from user in this file?
谢谢，

I read a tutorial in Django site but I don't understand how to use the set_language() function. For example, I have a demo follow as:
index.html
{% trans "Hello World." %}
<form action="/i18n/setlang/" method="post">
{% csrf_token %}
<input name="next" type="hidden" value="/next/page/" />
<select name="language">
{% get_language_info_list for LANGUAGES as languages %}
{% for language in languages %}
<option value="{{ language.code }}">{{ language.name_local }} ({{ language.code}})</option>
{% endfor %}
</select>
<input type="submit" value="Go" />
</form>
urls.py
urlpatterns = patterns('',
(r'^i18n/', include('django.conf.urls.i18n')),
)
views.py
What need I write to display the languages, which were chosen from user in this file?
Thanks,

使用您正在使用的代码，您不需要编写自己的视图。该表单将向 /i18n/setlang/ 发出 POST 请求，并以语言代码和（可选）重定向到（下一个）页面作为参数。
django 视图执行以下操作（来自 django 文档）
Django 在 POST 数据中查找下一个参数。
- 如果不存在或者为空，Django 会尝试 Referrer 标头中的 URL。
- 如果它是空的 - 比如说，如果用户的浏览器禁止该标头 - 那么用户将被 - 重定向到 / （站点根目录）作为后备。
因此本质上，用户在提交表单后将被重定向，并且 django 视图将根据提交的内容为该用户设置语言。
希望这有帮助，

With the code you are using, you don't need to write your own views. The form will make a POST request to /i18n/setlang/, with the language code and (optional) the redirect-to (next) page as parameters.
The django view does the following (from the django documentation)
Django looks for a next parameter in the POST data.
- If that doesn't exist, or is empty, Django tries the URL in the Referrer header.
- If that's empty -- say, if a user's browser suppresses that header -- then the user will be - redirected to / (the site root) as a fallback.
So in essence, the user will be redirected after submitting the form, and the django view will set the language for that user according to what was submitted.
Hope this helps,
