create a link_to in controller

link-to, ruby-on-rails

Solution

if you are using rails 3, you can use `view_context.link_to(...)` in your controller.

UPDATE: with the format.html code

format.html do
  redirect_to purchase_order_headers_path, notice: "PO already has RR with RR ID: #{view_context.link_to(rr.rr_id, receiving_record_header_path(rr.id))} void RR first.".html_safe
end

Problem

I need to pass a notice to a view from controller, and I want if can to create some link also to the notice. My controller: ``` format.html { redirect_to purchase_order_headers_path, notice: 'PO already has RR with RR ID: ' + rr.rr_id + ', void RR first.' } ``` Is there any way so I can do it so the `[rr.rr_id]` will become a link so when the user click on it will go to it's page? Since `link_to` will return error `"undefined method"` if put on controller. Thanks.
