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

try load data:

def database_load(arg='event_attendees.csv')   @contents = csv.open(arg, headers: true, header_converters: :symbol)   @people = []   @contents.each |row|     person = {}     person["id"] = row[0]     person["regdate"] = row[:regdate]     person["first_name"] = row[:first_name].downcase.capitalize     person["last_name"] = row[:last_name].downcase.capitalize     person["email_address"] = row[:email_address]     person["homephone"] = phonenumber.new(row[:homephone].to_s)     person["street"] = row[:street]     person["city"] = city.new(row[:city]).clean     person["state"] = row[:state]     person["zipcode"] = zipcode.new(row[:zipcode]).clean     @people << person   end   puts "loaded #{@people.count} records file: '#{arg}'..." end

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
