JBuilder json 带有@符号的键使用 json-ld 使用 schema.org 元数据

Question

在我的 jbuilder 模板中，我无法使用以“@”符号开头的键。例如“@语境”。我该怎么办

我的应用程序中 json-ld 元数据需要这样的密钥。

我想得到 json 如下所示

<script type="application/ld+json">

{
    "@context": "http://schema.org",
    "@type": "Article",
    "publisher": "The Ghost Blog",
    "author": {
        "@type": "Person",
        "name": "John O'Nolan",
        "image": "http://blog.ghost.org/content/images/2013/Nov/gravatar_j7_200.jpg",
        "url": "http://blog.ghost.org/author/john",
        "sameAs": "http://twitter.com/JohnONolan"
    },
    "headline": "11 Tools We Use at Ghost for Distributed Teams & Digital Nomads",
    "url": "http://blog.ghost.org/distributed-team-tools/",
    "datePublished": "2014-12-15T14:09:18.000Z",

}
    </script>
