Generate random text with Ruby
Jun 07, 2007
UPDATE: Changed the generate_password method slightly based on commenter Dave Burt's suggestion.
I'm working on a project where the user can reset their password if they've forgotten it. So, I need to generate a random password and email it to them so they can login and change it. Fortunately, I found this neat little Ruby snippet that will generate random text of a given length:
def generate_password(length=6)
chars = 'abcdefghjkmnpqrstuvwxyzABCDEFGHJKLMNOPQRSTUVWXYZ23456789'
password = ''
length.times { |i| password << chars[rand(chars.length)] }
password
end
Some examples:
generate_password >> U48ydn generate_password(10) >> QzWXdAkDy5
