JMSi18nRoutingBundle语言选择器 [英] JMSi18nRoutingBundle language selector

问题描述

我已经实现了以下语言切换器：

I have implemented the following language switcher:

<ul id="language-selector">
    {% if path(app.request.attributes.get('_route')) == '/' %}
        <li><a href="{{ path("homepage", {"_locale": "es"}) }}">ES</a></li>
        <li><a href="{{ path("homepage", {"_locale": "en"}) }}">EN</a></li>
        <li><a href="{{ path("homepage", {"_locale": "it"}) }}">IT</a></li>
    {% else %}
        <li><a href="{{ path(app.request.attributes.get('_route'), app.request.attributes.get('_route_params')|merge({'_locale': 'es'})) }}">ES</a></li>
        <li><a href="{{ path(app.request.attributes.get('_route'), app.request.attributes.get('_route_params')|merge({'_locale': 'en'})) }}">EN</a></li>
        <li><a href="{{ path(app.request.attributes.get('_route'), app.request.attributes.get('_route_params')|merge({'_locale': 'it'})) }}">IT</a></li>
    {% endif %}
</ul>

我正在使用 JMSi18nRoutingBundle 来翻译网址。它工作正常，但是当它呈现一个在URL中具有参数的视图时，会出现以下错误：

I'm using JMSi18nRoutingBundle for translating the urls. It works fine but when it renders a view which has a parameter in the url, the following error appears:

An exception has been thrown during the rendering of a template ("Some mandatory
parameters are missing ("id") to generate a URL for route
"es__RG__myapp_mybundle_myaction_edit".") in
MyAppMyBundle:Default:includes/myView.html.twig at line 21.

推荐答案

使用以下代码检查首页的条件

Use following condition to check for homepage

{％如果app.request.attributes.get（'_ route'）=='主页'％}

{% if app.request.attributes.get('_route') == 'homepage' %}

代替

{％if path （app.request.attributes.get（'_ route'））=='/'％}

{% if path(app.request.attributes.get('_route')) == '/' %}

说明：

访问需要参数的URL时，if语句 path（app.request.attributes中的代码。 get（'_ route'））生成错误。由于您的首页路由被定义为 主页 ，因此仅选中 _route 属性足以确定您正在访问主页。

Explanation:

When you are accessing an URL which required parameter(s), your code in if statement path(app.request.attributes.get('_route')) generates the error. As your home page route is defined as homepage, only checking the _route attribute will be enough to determine that you are accessing the homepage.

祝您编程愉快！
