How to assign a css class or id to link_to method in Ruby on Rails

Posted on 06 May 2006

To assign a css class or id to a link_to method you do the following:

<%= link_to "Link name", { :controller => 'controller_name', :action => 'action_name' }, :class => 'someclass' -%>

The key part is seperating the :controller => and :action from the html using the curly brackets.

• I would like to add a class to a single link. My problem is that I am getting those links from a loop:

  < @links.each do |link| > < link_to link.name, {}, :class=>‘red’ > < end >

  I would appreciate any help to do that? Thank you.

• I tried a few times to tack in the class where I also have an image_tag inside the link_to … without luck so far..I’ll come back with an answer if I get there !

• This should work:

  link_to(image_tag("image.gif"), { :controller => 'controller_name', :action => 'action_name' }, :class => 'someclass')

• Thanks, but how to pass html code to link_to with block?

  < link_to root_path, ?html_code? > ... < end >

• found it… if someone needs it, in order ti pass html attributes to link_to with block you have to call it with parenthesis:

  < link_to({:controller => “general”, :action => “act”}, :accesskey => “A”) >

  hope this helps
