邪恶精灵动态步序 [英] Wicked Wizard dynamic step order

问题描述

我正在尝试根据先前选择的选择更改 wicked Wizard 中的步骤顺序.

I'm trying to alter the order of the steps in wicked wizard based on the selections form a previous selection.

所以目前我已经完成了所有步骤:

So currently I have all the steps:

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

如果他们选择 :choice_a 等于 2，我只想包括步骤 :optional_page.我尝试了各种配置，但我遇到的真正问题是如果他们回到 :firstpage 并更改步骤并不总是正确的.我相信有人对此有很好的方法，任何帮助将不胜感激！！！

I want to only include the step :optional_page if they have selection :choice_a to equal 2. I've tried various configs but the real issue I run into is if they go back to the :firstpage and change the steps aren't always correct. I'm sure someone has a good approach to this, any help would be greatly appreciated!!!

推荐答案

  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
