Ruby On Rails：如何在rails中撤消nested_scaffold

Question

我使用nested_scaffold生成嵌套模型。我想删除模型Course。    我希望所有与课程相关的文件都应删除。但需要ClassRoom模型。关系也应该从ClassRoom删除，并且还应删除 route 文件。

  

我使用了以下命令来生成nested_scaffold：

rails generate nested_scaffold ClassRoom/Course name:string

Answer 1

撤消嵌套脚手架

rails destroy nested_scaffold ClassRoom/Course

Answer 2

您可以使用scaffold

销毁嵌套的脚手架

rails destroy scaffold class_room/course name:string

结果：

invoke  active_record
remove    db/migrate/20151006093322_create_class_room_courses.rb
remove    app/models/class_room/course.rb
invoke    test_unit
remove      test/models/class_room/course_test.rb
remove      test/fixtures/class_room/courses.yml
invoke  resource_route
route    namespace :class_room do
  resources :courses
end
invoke  scaffold_controller
remove    app/controllers/class_room/courses_controller.rb
invoke    erb
remove      app/views/class_room/courses
remove      app/views/class_room/courses/index.html.erb
remove      app/views/class_room/courses/edit.html.erb
remove      app/views/class_room/courses/show.html.erb
remove      app/views/class_room/courses/new.html.erb
remove      app/views/class_room/courses/_form.html.erb
invoke    test_unit
remove      test/controllers/class_room/courses_controller_test.rb
invoke    helper
remove      app/helpers/class_room/courses_helper.rb
invoke      test_unit
invoke    jbuilder
remove      app/views/class_room/courses
remove      app/views/class_room/courses/index.json.jbuilder
remove      app/views/class_room/courses/show.json.jbuilder
invoke  assets
invoke    coffee
remove      app/assets/javascripts/class_room/courses.coffee
invoke    scss
remove      app/assets/stylesheets/class_room/courses.scss
invoke  scss

然后你可以迁移它。

rake db:migrate

我希望这对你有所帮助。
