如果你正在使用一个单一的资源,脚手架的常规方法不起作用,有没有办法通过脚手架获得默认的奇异控制器？假如一个用户只有一个帖子,那么就可以运行一个简单的命令：
rails g scaffold post -singular
解决方法
当您查看Rails 3.1.1中的脚手架选项时,您将看到以下内容：
Usage: rails generate scaffold NAME [field:type field:type] [options] Options: ... ActiveRecord options: ... Rspec options: [--singleton] # Supply to create a singleton controller
rails g scaffold的输出帖子名称：string body：text –singleton is
invoke active_record create db/migrate/20111103072825_create_posts.rb create app/models/post.rb invoke rspec create spec/models/post_spec.rb route resources :posts invoke scaffold_controller create app/controllers/posts_controller.rb invoke haml create app/views/posts create app/views/posts/index.html.haml create app/views/posts/edit.html.haml create app/views/posts/show.html.haml create app/views/posts/new.html.haml create app/views/posts/_form.html.haml invoke rspec create spec/controllers/posts_controller_spec.rb create spec/views/posts/edit.html.haml_spec.rb create spec/views/posts/new.html.haml_spec.rb create spec/views/posts/show.html.haml_spec.rb invoke helper create spec/helpers/posts_helper_spec.rb create spec/routing/posts_routing_spec.rb invoke rspec create spec/requests/posts_spec.rb invoke helper create app/helpers/posts_helper.rb invoke rspec invoke assets invoke coffee create app/assets/javascripts/posts.js.coffee invoke scss create app/assets/stylesheets/posts.css.scss invoke scss identical app/assets/stylesheets/scaffolds.css.scss
所以脚手架似乎生成了通常的视图模板.
在Rails 3.0中,这是整个发生器的选项,而不仅仅是Rspec的选项.请参阅Railscast 216 for Generators in Rails 3.也许您会在Rails 3.0.x中找到满足您需求的生成器.
