I am trying to create a link to download a file from the file system. For this, I define the following in the "license_helper.rb" file:

def license_download_link(license, link_text = nil)
if link_text.blank?
  link_text = image_tag("download_icon.png", :border => 0, :width => 32, :height =>32,  :alt => 'Download License', :title => 'Download License')
end

tempLicenseFile = "tempLicense.xml"
File.open("#{tempLicenseFile}", 'w') do |tf|
  tf.puts license.data
end

command = "./runLicenseEncoder.bat #{tempLicenseFile}"
generateEncryptedLicenseFile = `#{command}`

theLicenseFile = "license.xml"
link_to link_text, "license/download"

end

My "view" just calls this helper class:

<td><%= license_download_link(license, ' ') %></td>

In the 'routes.rb' file, I have defined the following:

map.licensedownload "license.xml", :controller => 'licenses', :action => 'download' map.download "/licenses/download", :controller => 'licenses', :action => 'download'

In the 'controller', I have 'licenses_controller.rb' which includes the following:

def download theLicense = @license licenseFileName = "license.xml"

send_file "#{licenseFileName}" , :type => "application/xml", :filename => "#{licenseFileName}"

end

However, I am unable to obtain the '@license' attribute from the database in the controller. Could someone please let me know what I am doing wrong here and why I am unable to get the value for "@license".

Thanks for your time, Regards, --- AJ
