Rails 4-链接中的字体超赞图标

Question

Im trying to figure out how to make a link in my show page.

I want a link to

<%= @project.external_link %>.  

I want to display it as:

<%= link_to '<i class="fa fa-link"></i>' %>

I've tried at least 20 variations on combining these two and I can't find a way that works.

Does anyone know how to display a font awesome icon, with a link to a dynamic field?

Answer 1

Try this:

<%= link_to @project.external_link do %>
  <i class="fa fa-link"></i>
<% end %>

Answer 2

尝试使用：

<a href="<%= @project.external_link%>"><i class="fa fa-link"></i></a>
