Question

I am using Rails 3 and found that if I add
:remote => :true, there will be added to the tag the data-remote = true attribute. But I can’t find a way to add custom data- attributes to the urlhelper. The followings won’t work:

<%= link_to projects_path, :history => "new"%>
<%= link_to projects_path, :data-history => "new"%> #this throws an error
<%= link_to projects_path, :data_history => "new"%>

What I want to generate is:
New Project

anyone?

Answer 1

What about:

<%= link_to 'New Project', new_project_path, 'data-history' => 'new' %>
