How do i use a link_to inorder to go to a specific (html) ID on a page normally if i wanted to go to the "whatever_id" on a page i could use 

<a href="http://www.example.com/index/mypage#whatever_id>Click Here</a>

but i would like to use my link_to

<%= link_to "click here" , {:action => "mypage", :controller => "index" }, :id => "#whatever_id"%>

helper methods. Does anyone know how to do this? Is it possible?

Rails 2.3.4

link_to can add anchors to a URL.

From the documentation,

link_to "Comment wall", profile_path(@profile, :anchor => "wall")
# => <a href="/profiles/1#wall">Comment wall</a>

In your case you probably want,

 <%= link_to "click here" , {:action => "index", :controller => "mypage", :anchor => "whatever" } %>
