动态 CSS 生成在 Rails4 中不起作用 [英] Dynamic CSS generation doesn't work in Rails4

问题描述

以下代码不起作用，我需要根据 tale.id 的 vale 创建 css 类，如read-more-105"、read-more-106"等

The following code isn't working, I need to create css class like 'read-more-105','read-more-106' etc, according to tale.id's vale

<%= simple_format truncate(plot.description, length: char_counter){link_to "Read More",'', class: 'read-more-<% tale.id %>'} %>

推荐答案

你需要在这里进行字符串插值:

you need string interpolation here:

<%= simple_format truncate(plot.description, length: char_counter){link_to "Read More",'', class: "read-more-#{tale.id}" } %>

因为您不能在 <% %> 或 <%= %> 中包含 <% %>>.

As you can not have <% %> inside a <% %> or <%= %>.
