How to add a new action to the existing controller?

Question

I\'m pretty new in Rails. Sorry for the noob question.

I\'ve create a new controller: rails new controller Say hello goodbye

How can i add a new

Answer 1

When you repeat the generate command with another method's name, you can skip overwriting the existing controller and it's test implementation. That will automatically add the route and create a view. After that you have to add the method manually to the controller because that action didn't touch the controller file.

Example:

one method called new was already created in the controller when it was initially created:

$ rails generate controller Person new
... successfully created the controller, it's route and view ...

when trying to add a new method:

$ rails generate controller Person all
Running via Spring preloader in process 28648
    conflict  app/controllers/person_controller.rb
Overwrite ../app/controllers/person_controller.rb? (enter "h" for help) [Ynaqdh] h
    Y - yes, overwrite
    n - no, do not overwrite
    a - all, overwrite this and all others
    q - quit, abort
    d - diff, show the differences between the old and the new
    h - help, show this help
Overwrite ../app/controllers/person_controller.rb? (enter "h" for help) [Ynaqdh] n
        skip  app/controllers/person_controller.rb
       route  get 'person/all'
      invoke  erb
       exist    app/views/person
      create    app/views/person/all.html.erb
      invoke  test_unit
    conflict    test/controllers/person_controller_test.rb
Overwrite ../test/controllers/person_controller_test.rb? (enter "h" for help) [Ynaqdh] n
        skip    test/controllers/person_controller_test.rb
      invoke  helper
   identical    app/helpers/person_helper.rb
      invoke    test_unit
