Question

我想更改网页的当前语言。

我正在使用此HTML代码制作按钮：

<form action="{% url 'set_language' %}" method="post">
    {% csrf_token %}
    <input name="next" type="hidden" value="{{ request.get_full_path|slice:'3:' }}" />
    <ul class="nav navbar-nav navbar-right language menu">
        {% get_current_language as LANGUAGE_CODE %}
        {% get_available_languages as LANGUAGES %}
        {% get_language_info_list for LANGUAGES as languages %}
        {% for language in languages %}
            <li>
                <h1>{{ language }}</h1>
                <button type="submit"
                        name="language"
                        value="{{ language.code }}"
                        class="{% if language.code == LANGUAGE_CODE %}selected{% endif %}">
                    {{ language.name_local }}
                </button>

            </li>
        {% endfor %}
    </ul>
</form>

当我从西班牙语'es'切换到美国英语'en-us'时，我没有问题，但是当我尝试从美国英语切换到西班牙语时，请将此错误发送给我：

未找到： / i18n / setlang / -us /

在你的djangp应用程序中制作teamplatetags，如下所示：

模板标签文件

firebase init

<强> HTML

from django import template
from django.core.urlresolvers import resolve, reverse, Resolver404
from django.utils.translation import get_language, activate

register = template.Library()
@register.simple_tag(takes_context=True)
def change_lang(context, lang=None, *args, **kwargs):
    """
    Get active page's url by a specified language
    Usage: {% change_lang 'en' %}
    """
    path = context['request'].path
    full_path = context['request'].get_full_path()
    try:
        url_parts = resolve(path)
        cur_language = get_language()
        try:
            activate(lang)
            url = reverse(url_parts.view_name, kwargs=url_parts.kwargs)
            activate(cur_language)
            parameters = "?{0}".format(full_path.split('?')[1]) if len(full_path.split('?')) == 2 else ""
            return "{0}{1}".format(url, parameters)
        except Exception:
            pass
    except Resolver404:
        pass
    return full_path
