Ruby CSV enumeration confusion -

how come not work? csv there , has values, , have 'require "csv" , time @ top, there. problem seems csv.each doing anything.

it returns

=> [] common registration hour  => [] common registration day   (sunday being 0, mon => 1 ... sat => 7) 

if there more info can provide, please let me know.

@x = csv.open \ 'event_attendees.csv', headers: true, header_converters: :symbol   def time_target y = [] @x.each |line|     if line[:regdate].to_s.length > 0         y << datetime.strptime(line[:regdate], "%m/%d/%y %h:%m").hour         y = y.sort_by {|i| grep(i).length }.last     end end puts "#{y} common registration hour" y = [] @x.each |line|     if line[:regdate].to_s.length > 0         y << datetime.strptime(line[:regdate], "%m/%d/%y %h:%m").wday         y = y.sort_by {|i| grep(i).length }.last     end end puts "#{y} common registration day \ (sunday being 0, mon => 1 ... sat => 7)" end 

making 'y's '@y's has not fixed it.

here sample csv i'm using:

,regdate,first_name,last_name,email_address,homephone,street,city,state,zipcode
