ruby-on-rails - rails : prepend_before_action in superclass

Question

我的 ApplicationController 中有一个身份验证方法，我总是想先运行它。我在子 Controller 中还有一个方法，我想在身份验证方法之后运行，但在其他 ApplicationController before_actions 之前运行。换句话说，我想要这个:

ApplicationController
before_action first
before_action third

OtherController < ApplicationController
before_action second

以上导致方法按以下顺序调用: first -> third -> second .
但我想要订单: first -> second -> third .

我试过使用 prepend_before_action，如下所示:

ApplicationController
prepend_before_action first
before_action third

OtherController < ApplicationController
prepend_before_action second

但这导致它去 second -> first -> third .

我如何获得订单 first -> second -> third ?

Answer 1

您可以使用 prepend_before_action像这样:

class ApplicationController < ActionController::Base
  before_action :first
  before_action :third
end

class OtherController < ApplicationController
  prepend_before_action :third, :second
end
