Django 模板:获取另一种语言的当前 URL [英] Django templates: Get current URL in another language

问题描述

我正在使用 i18n_patterns 在 Django 应用中创建语言前缀.

I'm using i18n_patterns to create language prefixes in a Django app.

我的网址如下所示:

/de/contact/
/fr/contact/
/it/contact/

在我的基本模板中，我循环显示所有可用语言以显示语言切换链接.

In my base template, I'm looping over all available languages to show the language switch links.

{% get_available_languages as languages %}
<nav id="language_chooser">
    <ul>
        {% for lang_code, lang_name in languages %}
            {% language lang_code %}
            <li><a href="{% url 'home' %}" alt="{{ lang_name }}" title="{{ lang_name }}">{{ lang_code }}</a></li
            {% endlanguage %}
        {% endfor %}
    </ul>
</nav>

在这种情况下，我将反转主页"网址.有没有办法获取当前页面的翻译后的 URL?

In this case, I'm reversing the "home" URL. Is there a way to get a translated URL of the current page instead?

如果我在德语版的联系方式"页面上，我希望fr"链接指向法语版的联系方式"页面，而不是主页"页面.

If I'm on the German version of my "contact" page, I want the "fr" link to point to the French version of the "contact" page, not to the "home" page.

推荐答案

我没有使用语言前缀，而是使用翻译后的 url.但是，这个模板标签也应该对您有所帮助:

I'm not using language prefixes, but translated urls instead. However, this template tag should also help you:

# This Python file uses the following encoding: utf-8

from django import template
from django.core.urlresolvers import reverse # from django.urls for Django >= 2.0
from django.core.urlresolvers import resolve # from django.urls for Django >= 2.0
from django.utils import translation

register = template.Library()

class TranslatedURL(template.Node):
    def __init__(self, language):
        self.language = language
    def render(self, context):
        view = resolve(context['request'].path)
        request_language = translation.get_language()
        translation.activate(self.language)
        url = reverse(view.url_name, args=view.args, kwargs=view.kwargs)
        translation.activate(request_language)
        return url

@register.tag(name='translate_url')
def do_translate_url(parser, token):
    language = token.split_contents()[1]
    return TranslatedURL(language)

它以所需语言返回当前网址.像这样使用它:{% translate_url de %}

It returns the current url in the desired language. Use it like this: {% translate_url de %}
