Rails和haml,如何在link_to helper中添加id和类选择器？

Question

我一直在寻找如何使用辅助id器添加选择器,这可能吗？link_tohaml

  a .haml - %a#booked{:href => "index.haml"} Link 1    

  b .html.erb - booking.html.erb - <%= link_to "Link 1", booking_path, :id => "booked" %>

  c .haml.erb - booking.haml.erb - ...??

这相当于ha中的b？

Answer 1

link_to在haml中的工作方式与在erb中完全相同.所以这将做你想要的:

= link_to "Link 1", booking_path, :id => "booked"
#=> <a id="booked" href="/bookings">Link 1</a>

您还可以通过以下方式分配类属性:

= link_to "Link 1", booking_path, :id => "booked", :class => "some_class"
#=> <a id="booked" class="some_class" href="/bookings">Link 1</a>

并且,对于传递id和类没有任何疑问link_to,这是一个来自文档的示例:

link_to "Articles", articles_path, :id => "news", :class => "article"
#=> <a href="/articles" class="article" id="news">Articles</a>
