Question

我在我的应用中创建了这些控制器： rails generate controller pages index about

后来我决定创建一个新的（不确定它是否正确）但我收到警告因为pages已经存在：

$ rails generate controller pages contact

      invoke    scss                                                                                                                                                                             
   identical      app/assets/stylesheets/pages.css.scss

点击后输入一切正常，但在pages_controller.rb新网页contact未添加：

class PagesController < ApplicationController
  def index
    @notice = "Lorem ipsum dolor sit amet, consectetur adipiscing elit."
  end

  def about
  end
end

我是rails的新手，这是我的问题：这是向控制器添加新页面的正确方法吗？

我可以输入def contact来添加它，但可能还有另一种方法。手动添加一个页面是可以的，但如果我必须添加几个，那将是一场噩梦。如果不清楚我会尝试重新说出来。感谢。

如果你想完全更换控制器，首先要清除它是更清洁的：

 ~$ rails destroy controller pages
  remove  app/controllers/pages_controller.rb
  invoke  erb
  remove    app/views/pages
  invoke  test_unit
  remove    test/controllers/pages_controller_test.rb
  invoke  helper
  remove    app/helpers/pages_helper.rb
  invoke    test_unit
  remove      test/helpers/pages_helper_test.rb
  invoke  assets
  invoke    coffee
  remove      app/assets/javascripts/pages.js.coffee
  invoke    scss
  remove      app/assets/stylesheets/pages.css.scss

 ~$ rails generate controller pages contact
  create  app/controllers/pages_controller.rb
   route  get 'pages/contact'
  invoke  erb
  create    app/views/pages
  create    app/views/pages/contact.html.erb
  invoke  test_unit
  create    test/controllers/pages_controller_test.rb
  invoke  helper
  create    app/helpers/pages_helper.rb
  invoke    test_unit
  create      test/helpers/pages_helper_test.rb
  invoke  assets
  invoke    coffee
  create      app/assets/javascripts/pages.js.coffee
  invoke    scss
  create      app/assets/stylesheets/pages.css.scss

稍后在Rails中创建一个控制器
