多个角度请求会在测试中导致错误

我有一个带有Rails 4.0后端的Angular 1.5应用程序,我遇到了这个问题,在我的测试中,一名工作人员登录3个查询后,会同时发送到后端。在测试中(使用水豚+硒+铬无头),这会导致这些请求在后端出错。在开发中效果很好。

错误示例;

NoMethodError at /entities/get_current_entity
=============================================

> undefined method `fields' for nil:NilClass

app/controllers/application_controller.rb, line 79
--------------------------------------------------

``` ruby
   74   
   75     private
   76   
   77     def set_locale
   78       #I18n.locale = params[:locale] if params[:locale].present?
>  79       if current_staff.nil? or current_staff.locale.nil?
   80         I18n.locale = "en"
   81       else
   82         I18n.locale = current_staff.locale
   83       end
   84     end
```

失败的测试

require "rails_helper"

RSpec.describe "Login", :type => :feature do
  describe "login with existing staff member" do
    before do 
      create_admin
    end

    it "logs in as admin" do
      visit "#/login"
      fill_in "Email", with: "admin@test.com.au"
      fill_in "Password", with: "password"
      click_button "Login"

      within "#staff-status" do
        expect(page).to have_text('LOGOUT')    
      end

      within("#flash-messages") do 
        expect(page).to have_text('Successful login')
      end

      # Check session variables
      within("#selected-entity") do 
        expect(page).to have_text("LOGIN DEFAULT COMPANY")
      end

      within("#selected-ledger") do 
        expect(page).to have_text("My Ledger")
      end

      within("#selected-division") do 
        expect(page).to have_text("1-General")
      end
    end
  end
end

  $scope.$on('devise:new-session', (event, currentStaff) ->
    # staff logged in by Auth.login({...})
    Auth.currentUser().then((staff) ->
      FirmService.current_entity($rootScope)
      DivisionService.current_division($rootScope)
      LedgerService.current_ledger($rootScope)

      $rootScope.current_staff = staff
    , (error) ->
      console.log("fail")
    )

    $location.path "/dashboard"
  )

这在整个应用程序中都会发生,但在Rails 3.2上没有发生。自从我升级到Rails 4之后,这种情况才开始发生。

以下是登录的解决方法;

Auth.currentUser().then((staff) ->
  FirmService.current_entity($rootScope).then ->
    DivisionService.current_division($rootScope).then ->
      LedgerService.current_ledger($rootScope)

如何让Rails 4在测试模式下处理这样的多个请求?

我在测试环境中运行了我的服务器,试图手动复制问题,但这样做时它起了作用。所以这一定与测试的速度或水豚本身有关?

更新:更新的Gems

更新:错误

更新:调试

插入“需要撬”;结合撬开Rails控制器,AngularJS调用最终无法按预期工作。我在AngularJS代码中有三个调用,我预计Rails将三次进入调试行。第一次我用调试行运行它时,它只命中其中一行,第二次它没有命中任何调试行。相反,我在/entities/get\u current\u entity中得到了NoMethodError,在division和ledger中也是这样。

更新:查看撬吊

悬挂

在重新标记set_语言环境内容后,它继续进行,但仍然失败,并处于测试中。日志文件我得到了这些错误;

我认为截断表的最后一点是试图清理混乱的数据库清理器。所以我遇到的这三个服务器错误似乎超时了。为什么数据库/Rails会停止侦听查询?

当我键入一个简单查询时,pry也将挂起在set\u locale方法中

Staff.all

我获取了pry挂起时的strace输出; https://gist.github.com/map7/f25f75457f1a6ae6995934e2c2744660
