排除多个数据属性值引号的Rails标记语法

Question

尝试生成

<img data-interchange="[assets/img/interchange/small.jpg, small], [assets/img/interchange/medium.jpg, medium], [assets/img/interchange/large.jpg, large]">

是很有挑战性的。

<%= tag "img", data: { interchange: ["[#{photo.image_url(:base).to_s}, small]", "[#{photo.image_url(:big).to_s}, medium]", "[#{photo.image_url(:desktop).to_s}, large]"] } %>

将生成HTML，但结果仍不可操作

<img data-interchange="[&quot;[https://[...]base_20160529_115006.jpg, small]&quot;,&quot;[https://[...]big_20160529_115006.jpg, medium]&quot;,&quot;[https://[...]desktop_20160529_115006.jpg, large]&quot;]"  />

在生成"时。

获取正确的HTML字符串的正确语法是什么
