问题描述
我在我的 testapp 项目中使用了多个脚手架.
I'm using multiple scaffolding in my testapp project.
我已经创建了这样的第一个脚手架:
i have created 1st scaffold like this:
rails g 帖子标题 desc:text
它成功并创建了所有相关文件和控制器.
it was successful and created all relevant files and controller as well.
但是当我制作另一个脚手架时:
but when i made another scaffold :
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
它是空的,为什么会这样??
but when i open the controller app/controllers/products_controller.rb
it is empty, why so ??
还有一件事我也在使用 activeadmin,我知道它与它无关.
1 more thing i'm also using activeadmin, i know it has nothing to do with it.
推荐答案
我无法在基本的 Rails 安装中重现此问题:
I can't reproduce this on a basic Rails installation:
$ 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
拥有我期望的所有行:
After this, app/controllers/products_controller.rb
has all the lines I'd expect it to have:
$ wc -l app/controllers/products_controller.rb
74 app/controllers/products_controller.rb
也就是说,如果我将 ActiveAdmin 添加到 Gemfile:
That said, if I add ActiveAdmin to the 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,但几乎是:
my app/controllers/products_controller.rb
contains a lot less code. It's not empty, but almost:
class ProductsController < InheritedResources::Base
end
如果这也是您所看到的,那么您的问题是因为 ActiveAdmin 使用了继承的资源来完成一些繁重的工作.你最终得到了一个 InheritedResource 控制器.
If this is also what you're seeing, your problem comes from the fact that ActiveAdmin uses inherited_resources to do some of the heavy lifting. And you've ended up with am InheritedResource controller.
不过,控制器应该可以正常工作.
The controller should work perfectly fine, though.
