How to upload a file using send_file?

Can someone enlighten me how to upload a file using send_file?

I have a file image.jpginside app/assets/images. I tried this in my controller:

def download
    send_file ("#{Rails.root}/public/images/image.jpg")
end

def download
    send_file ("#{Rails.root}/assets/images/image.jpg")
end

def download
    send_file ("#{Rails.root}/images/image.jpg")
end

def download
    send_file ("/public/images/image.jpg")
end

def download
    send_file ("/assets/public/images/image.jpg")
end

def download
    send_file ("/assets/images/image.jpg")
end

For each path, he says:

ActionController::MissingFile in HomeController#download
Cannot read file 'some_path'

What could be the problem here? Thank!

Try:

IMAGES_PATH = File.join(Rails.root, "public", "images")

def download
  send_file(File.join(IMAGES_PATH, "image.jpg"))
end

In your view =>
<%= link_to "click here to download", signed_feeds_pdf_path(:feed_image_path => feed_image.feedimage.path), target: '_self' %>

In your controller =>
   def pdf
     file_name = params[:feed_image_path].split('/').last
     @filename ="#{Rails.root}/public/uploads/feed_image/feedimage/#{file_name}"
     send_file(@filename ,
      :type => 'application/pdf/docx/html/htm/doc',
      :disposition => 'attachment')           
  end
soo simple......

, . ,

send_file(Rails.root.join('app' , 'assets', 'images', 'image.jpg'))

, .

send_file ("#{Rails.root}/public"+image.image_path), :type => "image/jpeg", :disposition => 'inline'
+2

For those who are still looking for an answer, send_data and send_file will not work when answering ajax calls. Instead, try submitting the form, or using <a href=..>the controller method call and upload the file.
