Rake task to remove the image and audio files created by captcha
October 16, 2006
To add a rake task to the rails application which removes all the image and audio files created by captcha, create a file named remove_captcha_files.rake in the lib/tasks directory.
Add the following code to the lib/tasks/remove_captcha_files.rake file…
desc "Remove captcha images and audio files"
task :remove_captcha_files do
image_path = "#{RAILS_ROOT}/public/images/captcha/"
audio_path = "#{RAILS_ROOT}/public/captcha_audio/"
Dir.foreach(image_path){|file| File.delete(image_path+file) if (/^.*.jpg$/).match(file)} if File.exist?(image_path)
Dir.foreach(audio_path){|file| File.delete(audio_path+file) if (/^.*.wav$/).match(file)} if File.exist?(audio_path)
puts "Captcha files removed."
end
You can confirm that task is added to your app by running
rake –task
To remove all the files created by captcha, simply run the command
rake remove_captcha_files
from the command line from your application root.
