ruby-on-rails - 如何为 link_to block 传递 html？

Question

我试图用 html 传递 link_to block ，但无法获取它。我尝试了其他一些方法但没有成功，所以我将使用我的原始代码:

<% link_to survey_path(survey), :class => "button" do %>
   <span>add questions to <%= survey.name %></span>
<% end %>

但这并没有显示:class。

需要纠正什么？

Answer 1

尝试添加=做到<%= %>

<%= link_to survey_path(survey), :class => "button" do %>
   <span>add questions to <%= survey.name %></span>
<% end %>

In the view code in Rails 3 applications it’s sometimes necessary to use <%= instead of <% at the beginning of blocks that output content, such as form_for.

既然只是一个跨度，为什么不直接做

<%= link_to "add questions to #{survey.name}", survey_path(survey), :class => "button" %>
