Question

我在我的testapp项目中使用了多个脚手架。

我已经创建了第一个脚手架：

rails g Post title desc:text

它成功并创建了所有相关文件和控制器。

但是当我做了另一个脚手架时：

testapp$ rails g scaffold product name:string information:text 'price:decimal{7,2}' stock:integer available:boolean
      invoke  active_record
      create    db/migrate/20140513062549_create_products.rb
      create    app/models/product.rb
      invoke    test_unit
      create      test/models/product_test.rb
      create      test/fixtures/products.yml
      invoke  resource_route
       route    resources :products
      invoke  inherited_resources_controller
      create    app/controllers/products_controller.rb
      invoke    erb
      create      app/views/products
      create      app/views/products/index.html.erb
      create      app/views/products/edit.html.erb
      create      app/views/products/show.html.erb
      create      app/views/products/new.html.erb
      create      app/views/products/_form.html.erb
      invoke    test_unit
      create      test/controllers/products_controller_test.rb
      invoke    helper
      create      app/helpers/products_helper.rb
      invoke      test_unit
      create        test/helpers/products_helper_test.rb
      invoke    jbuilder
      create      app/views/products/index.json.jbuilder
      create      app/views/products/show.json.jbuilder
      invoke  assets
      invoke    coffee
      create      app/assets/javascripts/products.js.coffee
      invoke    scss
      create      app/assets/stylesheets/products.css.scss
      invoke  scss
   identical    app/assets/stylesheets/scaffolds.css.scss

但是当我打开控制器app/controllers/products_controller.rb时它是空的，为什么呢？

我还使用activeadmin，我知道它与它无关。

我无法在基本的Rails安装上重现这一点：

$ rails new empty && cd empty
$ rails g scaffold Post title desc:text
$ rails g scaffold product name:string information:text 'price:decimal{7,2}' stock:integer available:boolean

在此之后，app/controllers/products_controller.rb拥有我期望它拥有的所有行：

$ wc -l app/controllers/products_controller.rb
      74 app/controllers/products_controller.rb

那就是说，如果我将ActiveAdmin添加到Gemfile：

$ echo 'gem "activeadmin", github: "gregbell/active_admin"' >> Gemfile && bundle

并生成脚手架：

$ rails g scaffold product name:string information:text 'price:decimal{7,2}' stock:integer available:boolean

我的app/controllers/products_controller.rb包含的代码少得多。它不是空的，而是几乎：

class ProductsController < InheritedResources::Base
end

如果这也是您所看到的，那么您的问题来自于ActiveAdmin使用inherited_resources来完成一些繁重的工作。而且你最终得到的是InheritedResource控制器。

但是控制器应该可以正常工作。

脚手架轨道空控制器
