小编Sub*_*han的帖子

我正在使用Rails 4.0.0.rc2的ActiveAdmin(为Rails 4定制gemset).应用程序还具有基于railscast #385和#386的定制授权代码.

当我在ActiveAdmin资源文件中更改某些内容并尝试刷新浏览器页面时,我在该current_permission方法中收到此错误:

/ admin/courses中的ArgumentError

ApplicationController的副本已从模块树中删除但仍处于活动状态!

如果我再次尝试刷新,我得到:

自动加载常量权限时检测到循环依赖性

我认为这个问题与源文件发生变化后在开发模式下自动加载类有关.我见过类似的问题帖子,但它们适用于rails 2.3.x. 此外,解决方案似乎是unloadable在控制器中指定抛出此错误,但我不确定在ActiveAdmin中放入此代码段的位置.

这可能与ActiveAdmin无关.它可能与如何构建Permissions类及其在Application Controller中的使用有关.如果我skip_before_filter :authorize在ActiveAdmin资源类中添加一个,则此错误消失.

ApplicationController中:

class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception

  before_filter :authenticate_user!
  before_filter :authorize

  delegate :allow_action?, to: :current_permission
  helper_method :allow_action?

  delegate :allow_param?, to: :current_permission
  helper_method :allow_param?

  private
    def current_permission
      @current_permission ||= Permissions.permission_for(current_user)
    end

    def current_resource
      nil
    end

    def authorize …

我在我的应用程序中使用Devise,并尝试编写更新电子邮件ID的规范.用户界面工作,但规格失败.在测试更改的电子邮件ID之前,我也在重新加载用户对象.

我观察到的一件事是在数据库上运行UPDATE USERS语句.

编写规范的正确方法是什么？

RSpec规格:

it "should update email" do
  @user = subject.current_user
  patch :update, id: @user, user: {:email => "john.doe@example1.com"}
  @user.reload
  expect(@user.email).to eq("john.doe@example1.com")
end

RSpec错误日志:

1) Users::RegistrationsController logged in user should update email
   Failure/Error: expect(@user.email).to eq("john.doe@example1.com")

   expected: "john.doe@example1.com"
        got: "john.doe@example.com"

   (compared using ==)

test.log中:

   (0.2ms)  BEGIN
   (0.4ms)  SAVEPOINT active_record_1
