Rails:功能和ActiveAdmin无法按预期工作

我正在使用ActiveAdmin和Cancancan开发Ruby on Rails项目。我为角色用户定义了一些功能,例如super_administratoradministratorsubscribers

在写了一些单元测试之后,我发现了能力不能正常工作,我无法弄清楚出了什么问题。

具体而言,我有一个简报模块,我只想administratorsuper_administrator来管理它。

这是我的能力摘录

class Ability
  include CanCan::Ability

  def initialize(user)
    user ||= User.new # visitor user (not logged in)

    alias_action :create, :read, :update, :destroy, to: :crud

    if user.super_administrator?
      # super_administrator privileges
    elsif user.administrator?
      # administrator privileges
    elsif user.subscriber?
      cannot :manage, Newsletter
    else
      cannot :destroy, :all
      cannot :update, :all
      cannot :create, :all
      cannot :manage, Newsletter
    end
  end
end

我的测试

# this test breaks for no reason
test 'should not destroy newsletter if logged in as subscriber' do
  sign_in @subscriber
  assert_no_difference 'Newsletter.count' do
    delete :destroy, id: @newsletter
  end
  assert_redirected_to admin_dashboard_path
end

private

def initialize_test
  @newsletter = newsletters(:one)
  @subscriber = users(:alice)
end

此测试中断,因为即使我写了订阅者不管理时事通讯的能力,时事通讯也会被销毁。

奇怪的是,如果我测试订阅者的能力,一切正常:

# this test pass as expected by ability
test 'should test abilities for subscriber' do
  sign_in @subscriber
  ability = Ability.new(@subscriber)
  assert ability.cannot?(:create, Newsletter.new), 'should not be able to create'
  assert ability.cannot?(:read, Newsletter.new), 'should not be able to read'
  assert ability.cannot?(:update, Newsletter.new), 'should not be able to update'
  assert ability.cannot?(:destroy, Newsletter.new), 'should not be able to destroy'
end 

我尝试直接在浏览器中手动测试,而且功能也不起作用。

我不明白我错过了什么。有人对我的代码有什么问题有任何疑问吗?

我的项目

  • Ruby 2.2.2
  • Rails 4.2.3
  • ActiveAdmin 1.0.0 pre1
  • Cancancan 1.12.0

1 个答案:

答案 0 :(得分:0)

经过数小时和数小时的调查,我发现问题来自与ActiveAdmin同名的变量(具有正确的能力)并且覆盖了它们(具有不良能力)。
在我的ApplicationController中更改变量名称修复了所有带有Abilities的错误。
