coba di view source
elemen HTML form-nya bener keluar ada ID nya nggak?
kalo nggak keluar berarti @album.id nya Nil
kalo begitu baris ini :
> <% form_tag :action => "update", :id => @album.id do %>
>
coba diganti jadi :
> <% form_tag :action => "update", :id =>params[:id] do %>
>
dengan pertimbangan restful routes
semoga bener :)
