Wagtail modeltranslation language switcher doesn't work on /search page

问题

I have added search url to i18n_patterns, but the language switcher doesn't work on that page.
urls.py:

urlpatterns += i18n_patterns(
    path("search/", search_views.search, name="search"),
    path("", include(wagtail_urls)),
)

language switcher:

{% get_available_languages_wmt as languages %}
<div class="nav-item dropdown float-right">
    <p class="nav-link dropdown-toggle m-auto" data-toggle="dropdown" role="button" aria-expanded="false">
        {{ request.LANGUAGE_CODE|upper }}</p>
    <div class="dropdown-menu w-25">
        {% for language in languages %}
        {% if language != request.LANGUAGE_CODE %}
        <a class="dropdown-item" href="{% change_lang language page %}">{{ language|upper }}</a>
        {% endif %}
        {% endfor %}
    </div>
</div>

Furthermore, when i add search url above root one the search page raises 404 page. How can i make the language switcher work on the search page?

回答1:

The language switcher uses the Wagtail page variable. See the change_lang template tag:

<a ... href="{% change_lang language page %}">...</a>

And search is a Django view, not a Wagtail page. The page variable is not defined.

You can make the switcher work on the search view by setting the href yourself:

{% for language in languages %}
    <a href="/{{ language.code }}/search/"
{% endfor %}

Alternatively, you can create a Wagtail search page:

class SearchPage(Page):
    def get_context(self, request):
        context = super().get_context(request)            

        ... # Copy the code from the current search view.

        # Update and return the context
        context.update({
            'search_query': search_query,
            'search_results': search_results,
        })
        return context

https://docs.wagtail.io/en/latest/topics/pages.html#customising-template-context

You also have to:

Rename (search_page.html) and rework (page.variable_name) your search template.
Remove the search url from urls.py
Add the SearchPage via the Wagtail admin interface to the page tree.
