ruby-on-rails-4 - 邪恶巫师动态步骤顺序

Question

我正在尝试根据先前选择的选择来更改邪恶向导中的步骤顺序。

所以目前我已经完成了所有步骤:

class WWTestController < ApplicationController
  include Wicked::Wizard
  steps :first_page,:optional_page,:second_page

   def show
     @event_object = EventObject.find(params[:event_object_id])

     render_wizard
   end

   def update
     @event_object = EventObject.find(params[:event_object_id])
     @event_object.update_attributes(event_object_params)

     render_wizard @event_object
   end

   private

   def event_entry_params
    params.fetch(:event_object, {}).permit(:choice_a)
   end

end

如果选择 :choice_a 等于 2，我只想包含步骤 :Optional_page。我尝试了各种配置，但我遇到的真正问题是，如果他们返回 :firstpage 并更改步骤并不总是正确的。我确信有人对此有一个很好的方法，任何帮助将不胜感激!!!

Answer 1

  def show
    @event_object = EventObject.find(params[:event_object_id])

    # Extra logic based on flow steps - when to skip sth.
    case step
    when :optional_page
      skip_step unless @event_object.choice_a == 2
    end

    render_wizard
  end
