Rails - Jan 2006 - Passing parameters with link_to

I have following code in my controller:

class AlbumsController < ApplicationController
  def list_by_year(year)
    @album_pages
    @albums = paginate :albums,
                       { :per_page => 10,
                         :conditions => ["year = ?", year] }
    render :action => ''list''
  end
end

Now I want to make a link to the list_by_year action in show.rhtml

<%= link_to @album.year,
            { :action => ''list_by_year'' },
            {},
            @album.year %>

Isn''t this what the *parameters_for_method_reference is for? Obviously 
not because I get:

wrong number of arguments (0 for 1)

What is the correct way to pass this parameter? Haven''t found anything 
by googling.

I don''t think you can pass parameters this way.

You can submit it through the params hash like this

class AlbumsController < ApplicationController
 def list_by_year
     year = params[:year]
     @album_pages,
     @albums = paginate :albums,
                        { :per_page => 10,
                          :conditions => ["year = ?", year] }
     render :action => ''list''
   end
 end

<%= link_to @album.year,
             { :action => ''list_by_year'' },{:year =>
@album.year} %>
