Rails Pundit 访问参数或对象

Question

我有两个模型 - Physician 和 Patient。医师只能向其帐户中已完成 phone 编号的患者提供建议，否则应将医师重定向至编辑患者页面。下面是我的代码：

recommendation_controller.rb新方法

  def new
    authorize Recommendation
    @registrant = Registrant.find(params[:registrant_id])
    @recommendation = Recommendation.new(patient: @registrant)
  end

政策

class RecommendationPolicy < ApplicationPolicy
  def new?
    login.physician?
  end
end


class ApplicationPolicy
  attr_reader :login, :record

  def initialize(login, record)
    raise Pundit::NotAuthorizedError, "must be logged in" unless login
    @login = login
    @record = record
  end
end

所以问题是如何将@registrant 对象传递给 new? 策略以检查该注册人是否有 phone 号码？

Answer 1

我将在 RegistrantPolicy 下创建自定义权限以检查是否允许推荐。

政策：

class RegistrantPolicy < ApplicationPolicy
  def recommendation_allowed?
    record.phone_number.present?
  end
end

并在 recommendation_controller.rb 中应用它，例如

  def new
    authorize Recommendation
    @registrant = Registrant.find(params[:registrant_id])
    authorize @registrant, :recommendation_allowed?
    @recommendation = Recommendation.new(patient: @registrant)
  end
