Ruby on rails file download link

I created file upload using paperclip! File uploads as it is supposed to. Than I added file download method like this:

def download
    sample = Sample.find(params[:id])


    send_file  upload.sample.path,
    :filename => upload.sample_file_name,
                :type => upload.sample_content_type,
    :disposition => 'attachment'
    flash[:notice] = "Your file has been downloaded"
  end

But I cant figure out, what should I put in my show action so that I would be able to download the file?

I got as far as this:

<td><%= @sample.upload_file_name =%></td>
    <%= link_to 'Download', :action => :download, :path =>@sample.upload.url, :type => @sample.upload_content_type %>

But it shows error : Couldn't find Sample with id=download

Can anyone help me?

It looks like you have mismatch in your routes.

That is why, you have to:

  1. Add additional route to your routes.rb for download action.
  2. As it was said previously, you have to add link to your view (link_to).

Assuming you set download named route properly, you can just say

<%= link_to 'Download', download_sample_path(@sample) %>

Think you need to change your link_to to send the :id (that's what the controller action is looking for with params[:id])

<%= link_to 'Download', :action => :download, :id => @sample.id %>

Soz Karlis was writing as you posted :D
