LinkedInEver want to get a random image from a folder in your rails app? Well, here you have it…place this in your application helper:
# Methods added to this helper will be available to all templates in the application.
module ApplicationHelper
def random_header_image
image_files = %w( .jpg .gif .png )
files = Dir.entries(
"#{RAILS_ROOT}/public/images/random_image_folder"
).delete_if { |x| !image_files.index(x[-4,4]) }
files[rand(files.length)]
end
end
module ApplicationHelper
def random_header_image
image_files = %w( .jpg .gif .png )
files = Dir.entries(
"#{RAILS_ROOT}/public/images/random_image_folder"
).delete_if { |x| !image_files.index(x[-4,4]) }
files[rand(files.length)]
end
end
