Django templates: Get current URL in another language

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

My URLs look like this:

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

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>

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

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.

This solution should work for all URLs except when the arguments are language-dependent, as @Flash told us in the comments. I have simplified and updated the following code, so it will work with current Django versions >=3.

from django import template
from django.urls import resolve, reverse
from django.utils import translation

register = template.Library()

@register.simple_tag(takes_context=True)
def translate_url(context, language):
    view = resolve(context['request'].path)
    request_language = translation.get_language()
    translation.activate(language)
    url = reverse(view.url_name, args=view.args, kwargs=view.kwargs)
    translation.activate(request_language)
    return url

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

Comments and suggestions for improvements are welcome.
