Ruby on rails Rails-Gem-Flash消息

我有一个活动模型，我正在使用邪恶宝石一步一步创建活动

我在向导中总共有3个步骤

steps :details, :audiance, :creatives

这是我的向导控制器

class Brands::CampaignWizardsController < Brands::ApplicationController
  include Wicked::Wizard
  steps :details, :audiance, :creatives

  def show
    @campaign = current_company.campaigns.friendly.find(params[:campaign_id])
    render_wizard
  end

  def update
    case step
      when :details
        @campaign.attributes = campaign_details_params

        @campaign[:dos].delete_if(&:blank?)
        @campaign[:donts].delete_if(&:blank?)

        @campaign_ideas = CampaignIdea.where(objective_id: @campaign.objective_id)

      when :audiance
        @campaign.attributes = campaign_audiance_params

        @campaign[:influencer_interests].delete_if(&:blank?)

      when :creatives
        @campaign.attributes = campaign_creatives_params

    end
    render_wizard @campaign
  end
end

类别品牌：：活动向导控制器

我想在向导的每个步骤中添加flash消息（成功/错误）

---

是否有任何方法可以将我的消息作为选项{}传递到渲染向导？

您应该能够通过以下方式实现这一点：

flash[：notice]=“活动已成功更新
