ruby-on-rails – Wicked Wizard控制器中的非静止动作

控制器：

class Books::BookUpdateController < ApplicationController

  include Wicked::Wizard
  steps :title_step,:ai_archive_step,:ai_override_step #etc

   def show
      ...
   end

   def update
      ...
   end

   def waterfall
      ...# loads of code to set up instance variables in the view,which I don't want to have to include in the normal show action for all the wizard steps. 
   end
end

路线：

resources :book_update do     
  member do
    get 'waterfall'
    ... and others 
  end
end

版本1和更低版本的gem允许非静态操作,但this commit解决this PR强制执行步骤名称.我去这条路线的错误http：// localhost：3000 / book_update / 3949 / waterfall是

Wicked::Wizard::InvalidStepError in Books::BookUpdateController#waterfall

The requested step did not match any steps defined for this controller.

我想我应该激发一个新的控制器并将非静止的动作塞进那里,但替代方案会很棒.
