添加自定义数据属性 rails 图像标记 [英] Adding custom data attributes rails image tag

问题描述

我需要在我的 rails 应用程序中为 Galleria 添加数据描述和数据标题，但我看不到如何使用图像标签来做到这一点.到目前为止，我有这个:

<% @entries.each 做 |entry|％＞<%= image_tag entry.filename, :title =>"标题", :class =>"class", :data-description =>entry.caption, :data-title =>entry.caption %><%结束%>

但这会引发未定义的局部变量或方法描述"错误，那么我将如何在 rails 3 中执行此操作?

解决方案

正确的语法是

<%= image_tag entry.filename, :title =>"标题", :class =>"类", :data =>{:描述=>entry.caption, :title =>entry.caption } %>

I need to add data-description and data-title for galleria in my rails application but I can't see how to do this with the image tag. So far I have this:

<div id="galleria">
<% @entries.each do |entry| %>
     <%= image_tag entry.filename, :title => "title", :class => "class", :data-description => entry.caption, :data-title => entry.caption  %>
 <% end %>
 </div>

But this raises the undefined local variable or method `description' error, so how would I do this in rails 3?

解决方案

The correct syntax for this is

<%= image_tag entry.filename, :title => "title", :class => "class", :data => { :description => entry.caption, :title => entry.caption }  %>
