哈姆尔"Illegal Nesting"问题;如何在同一个标签中放置多个代码元素？

Question

- @subjects.each do |s|
  %tr
  %td= s.position
  %td= s.name
  %td= s.visible ? "Yes" : "No"
  %td= s.pages.size
  %td= link_to("Show", {:action => "show", :id => s.id}, :class => "action show") 
    = link_to("Edit", {:action => "edit", :id => s.id}, :class => "action edit")
    = link_to("Delete", {:action => "delete", :id => s.id}, :class => "action delete")

error_msg:

非法嵌套:内容不能与%td同时出现在同一行并嵌套在其中。

我希望这三个链接——显示、编辑和删除——在同一个目录中;我该怎么做呢?

Answer 1

你只需要改变这个:

%td= link_to("Show", {:action => "show", :id => s.id}, :class => "action show") 
  = link_to("Edit", {:action => "edit", :id => s.id}, :class => "action edit")
  = link_to("Delete", {:action => "delete", :id => s.id}, :class => "action delete")

:

%td
  = link_to("Show", {:action => "show", :id => s.id}, :class => "action show") 
  = link_to("Edit", {:action => "edit", :id => s.id}, :class => "action edit")
  = link_to("Delete", {:action => "delete", :id => s.id}, :class => "action delete")

您还应该从tr缩进td s。

供参考-我也遇到了这个问题，但罪魁祸首是我的<td>之后的尾随空间，这是HAML的内容。
