Rails 4：从模型类获取控制器类

Question

是否有任何简单的方法从Model类获取控制器类名？ 例子：

Invoice => InvoicesController 

尝试tabalize但它返回 “发票”

Invoice.to_s.tabalize => "invoices" 

Answer 1

s = Invoice 
s.name.pluralize + 'Controller' 
=> "InvoicesController" 

为了让控制器类本身...

"InvoicesController".constantize 
=> InvoicesController
