How to add parameter to delete link?

Question

I have a standard delete link, and want to add a parameter to it:

<%= link_to "Delete", item, :confirm => 'Are you sure?', :method => :delete, :foo => 1 %>

The parameter shows up in the html a tag, but does not make to the server. I get "undefined local variable or method `foo'".

Here is how I am accessing it in the controller:

def destroy
    puts "params[:foo]:" + params[:foo].to_s 
    .
    .
    .
    redirect_to edit_bar_path(params[:foo])

The output is params[:foo]:

Answer 1

<%= link_to "Delete", item_path(:id => item.id, :foo => 1), :confirm => 'Are you sure?', :method => :delete %>

Answer 2

I think you are looking for:

item_path(item, :foo => 1)

It should appear in your params
