访问模型中的rails flash[:notice]

我需要设置 flash[:notice] 在模型中重写泛型“@model was successfully updated”。

我就是这么做的

1. 在相应的模型中创建了一个名为 flash_notice
2. 然后根据需要在相应的模型中设置虚拟属性
3. 当此虚拟属性不为空时使用after_筛选器覆盖默认闪存

你可以在下面看到我的控制器和模型,我是如何做到这一点的:

class Reservation < ActiveRecord::Base

  belongs_to :retailer
  belongs_to :sharedorder
  accepts_nested_attributes_for :sharedorder
  accepts_nested_attributes_for :retailer

  attr_accessor :validation_code, :flash_notice

  validate :first_reservation, :if => :new_record_and_unvalidated

  def new_record_and_unvalidated
    if !self.new_record? && !self.retailer.validated?
      true
    else
      false
    end
  end

  def first_reservation
    if self.validation_code != "test" || self.validation_code.blank?
      errors.add_to_base("Validation code was incorrect") 
    else
      self.retailer.update_attribute(:validated, true)
      self.flash_notice = "Your validation as successful and you will not need to do that again"
    end
  end
end

class ReservationsController < ApplicationController

  before_filter :authenticate_retailer!
  after_filter :flash_notice, :except => :index

  def flash_notice
    if !@reservation.flash_notice.blank?
      flash[:notice] = @reservation.flash_notice
    end
  end
end

不,您在进行保存的控制器中设置它。 flash 是在 ActionController::Base .
