What\'s the best way to create a download link? Is there a better way than the following?

I was thinking of using link_to \"Download\", :controller => ..., :act

    You could just have your download logic in your show action and give it:

    <%= link_to "Download", document_path(document) %>
    

    I'm pretty sure that the :controller / :action / :id method of linking is frowned upon.

    I add the download action as a restful route in a resources block. Here's typical code for me:

    routes.rb

      resources :things do
        member do
          get :download
        end
      end    
    

    model:

      has_attached_file :document,
        :path => ':rails_root/assets/documents/:id/:basename.:extension'
      attr_protected :document_file_name, :document_content_type, :document_file_size
    

    controller:

      def download
        send_file @thing.document.path, :type => 'application/pdf', :filename => @thing.permalink
      end
    

    view:

      <%= link_to 'Download', download_thing_path(@thing) %>
    

    This keeps the user on the same page, and just initiates the download with my suggested name (I use permalink).

    What do you mean by dynamically generated? Are they uploaded by you or created by your application on the fly?

    I've just created a Download .mp3 link and used in my .htaccess file.

    <Files *.mp3>
      ForceType application/octet-stream
      Header set Content-Disposition attachment
    </Files>
    

    I found this to be easier than any other solution.
