2 hi, my name is amy hoy

3 but... let s talk about you

4 you... have a problem

6 script/console generate scaffold foo

7 POW!

8 exists app/controllers/ exists app/helpers/ create app/views/foos create test/functional/ dependency model create app/models/ create test/unit/ create test/fixtures/ create app/models/foo.rb create test/unit/foo_test.rb create test/fixtures/foos.yml create app/views/foos/_form.rhtml create app/views/foos/list.rhtml create app/views/foos/show.rhtml create app/views/foos/new.rhtml create app/views/foos/edit.rhtml create app/controllers/foos_controller.rb create test/functional/ foos_controller_test.rb create app/helpers/foos_helper.rb create app/views/layouts/foos.rhtml create public/stylesheets/scaffold.css

9 it s like... magic

10 magic that sucks!

14 the beginnings of withdrawal

15 how do I make scaffolding...

16 create prettier forms? link models? create multiple objects?

17 ?????????????

19 scaffolding is not the answer

22 ugly

23 associationignorant

24 2 Jar 1 Kitten yeah right

25 class Kitten < ActiveRecord::Base belongs_to :jar end class Jar < ActiveRecord::Base has_many :kittens end

26 code excess

28 too damn many files

30 brainnumbing

31 fresh start, cold turkey

32 pssst, this is turkey brrrrrr

33 what do you need?

34 kittens create view edit feed put to sleep jars create edit delete?

36 script/generate controller kittens create view edit feed put_to_sleep

37 script/generate controller kittens create view edit feed put_to_sleep

38 script/generate controller kittens create view edit feed put_to_sleep

39 app/controllers/kittens_controller.rb

40 script/generate model kitten --skip-migration script/generate model jar --skip-migration

41 script/generate model kitten --skip-migration script/generate model jar --skip-migration

42 script/generate model kitten --skip-migration script/generate model jar --skip-migration

43 app/models/jar.rb and kitten.rb

45 app/models/jar.rb and kitten.rb

46 new and create, together at last

49 app/views/kittens/create.rhtml

50 app/views/kittens/create.rhtml

52 but...

53 app/views/kittens/create.rhtml

55 /kittens/create Kittens Controller kittens_controller.rb if(params[:kitten])... yep! nope! nope! yep! as yet unspecified show form create.rhtml

56 incomiiiing!

57 app/views/kittens/create.rhtml this outputs a YAML dump of any object

59 any view! any controller!

60 linky linky

61 app/controllers/kittens_controller.rb

62 saving might be nice

63 app/controllers/kittens_controller.rb

64 app/controllers/kittens_controller.rb

66 app/controllers/kittens_controller.rb

67 app/views/kittens/view.rhtml

68 app/views/kittens/view.rhtml

70 isn t that refreshing?

71 please! no more code! Photo Malingering,

72 other fun things to do with forms

73 partials use other field types create multiple associations create a bunch of records

74 i m partial

75 app/views/kittens/create.rhtml create this file app/views/kittens/_kitten_form.rhtml the preceeding underscore means "it's a partial"

76 select menus kinda hurt. ow.

77 step 1: preload data in controller step 2: create select tag in view step 3: there is no step 3!

78 dealing with multiple associations

79 2 Jar 1 Kittens OMG

80 step 1: helper method for checks step 2: call helper in view

81 step 3: deal with array in controller

82 creating multiple records

83 step 1: in your view step 2: in your controller

84 aggregate controllers

85 in any controller, use any model

86 app/controllers/home_page_controller.rb

87 not every model requires a controller

88 not every action requires a view

89 app/controllers/home_page_controller.rb

90 filters are fun

91 app/controllers/home_page_controller.rb

92 layouts, partials, views

93 layouts wrap actions unless you turn 'em off layout action view partial partial partial partial partial partial partial partials can go anywhere... including inside other partials action views: where the action is & they're mapped to controller methods Ruby on Rails Right-Brained Guide

94 deep breath relax
