Question

I followed this guide learning how to do file uploads to a secure directory on my server, rather than public (default). When I try to go to the show to view the links, I get:

undefined method `redocument' for #<ActionView::Helpers::FormBuilder:0xa2ae338>
near: <%= link_to File.basename(f.redocument.url), "/uploads/#{f.id}/#{File.basename(f.redocument.url)}" %> 

It is having trouble rendering the link. Am I missing something here? Am I not supposed to copy this code line by line? They don’t specify whether or not I should be replacing ‘redocument’, but my model name is Entry, and the string the file’s link is stored is mv_link. Anyone have any idea what the fix is?

Update: Hopefully in the right direction

I changed all the cases of ‘f.redocument’ to ‘@entry.mv_link’. Now on the show page, the link is there. However when I click it and try to download, the path specified by the controller is broken. This is what the controller was

def download
  path = "/#{redocument.redocument}"
  send_file path, :x_sendfile=>true
end

What should I change this path to?

OK, going on a limb here… But I think you have something like this setup:

class Entry < ActiveRecord::Base
  mounts_uploader :mv_link, YourUploaderClass
end

In your controller, you need to find the Entry and then get the path form the mv_link

def download
  @entry = Entry.find(params[:id])
  send_file @entry.mv_link.path, disposition: 'attachment', x_sendfile: true
end
