showing /users/overallduka/youimports_app/app/views/tasks/index.html.erb line #6 raised:

undefined method `link_to_remote' #<#:0x10216ff00> extracted source (around line #6):

<% @tasks.each |task| %> &nbsp;<%= task.title %><br /> <p class="about_task"><%= link_to_remote (status(task.status)),"alert('aaa')" %> <%= task.about %></p> <% end %>

link_to_remote , other remote ajax helpers have been removed in rails 3 , moved gem https://github.com/rails/prototype_legacy_helper. if trying run simple js after clicking link, utilize link_to_function instead

link_to_function 'test_alert', 'alert("test")'
