Help with PDF Writer and link_to

I have this code in the controller:

   def search2
     @repair_tickets =
RepairTicket.search(params[:search][:client_id],params[:search][:product_id],params[:search][:status_id],params[:search][:pos_breakdown_id],params[:search][:breakdown_id],params[:search][:query])
     respond_to do |format|
       format.html
       format.pdf do
         send_data SearchRepairTicketDrawer.draw(@repair_tickets),
:filename => 'repair_tickets/search2/@repair_tickets.pdf', :type =>
'application/pdf', :disposition => 'inline'
       end
      end
  end

And I have this code in search2.html.erb:

  ...

<p> <%= link_to 'PDF Format',
formatted_repair_ticket_path(@repair_tickets, :pdf) %> </p>

I want this last link to link to the pdf wich I create in search2
method. If I quit the format.html line, it generates the pdf I want, but
i want a link to do it. Help!

I have tried this link_to:

<p> <%= link_to 'PDF Format', :controller => "repair_tickets", :action
=> "search2", :format => "pdf" %> </p>

Then I get that search2.pdf doesn't exist, but it i quit the line
format.html, I get the pdf (but in the line of the explorer I don't get
.pdf)
