Takes a string, such as a post title ("Rat Brains Fly Planes") and convets it into a ruby style variable name that can be used as an id or permalink url ("rat_brains_fly_planes") Posted by Duane Johnson on rails list: Here's the modified String class. This one squeezes non-alphanumeric character sequences down to one underscore and also makes sure it doesn't start or end with an underscore:
class String def rubify downcase.gsub(/\W/, ' ').squeeze.strip.gsub(' ', '_') end def rubify! replace rubify end end"!Hell93 o3#$@ the___re , dude".rubify => "hel93_o3_the_re_dude" Luke Redpath suggested the following naming convention: ID is short for identification the related verb of which is identify. The appropriate verify_ macro would be verify_identity_of A more conventional Ruby idiom would be to_id() (like to_s, to_i etc.).
"My, what a beautiful day!".to_id => "my_what_a_beautiful_day"If thats not clear enough or possibly confusing with the normal use of id in a Rails app, perhaps to_identifier() instead.
