ruby-on-rails – Rspec请求规格中的Rails 4中的循环依赖错误

Ruby 前端之家
前端之家收集整理的这篇文章主要介绍了ruby-on-rails – Rspec请求规格中的Rails 4中的循环依赖错误，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
我有一个运行在Rails 4 / Ruby 2上的应用程序.前端正在使用Ember开发.

当运行rake规范时,我得到以下异常.它似乎只发生在Rspec功能规格(不是在开发模式).此外,通常只有在我运行一个功能规格时才会发生;如果我运行整个测试套件,我通常不会得到错误.

由于此提交到Rails,发生错误：
https://github.com/rails/rails/commit/b33700f5580b4cd85379a1dc60fa341ac4d8deb2

但是,当然,我不知道这是真正的问题,还是在调用堆栈中更深入.我知道,如果我在Rails代码中进行最小的更改,以免抛出该错误,一切似乎都可以正常工作,我的测试通过.但是,某处,似乎正在尝试加载LocationsController,即使它已经加载.

任何帮助都非常感激,因为这个我真的很难受.

我试过的

>更改我的路线的名称和路径,认为垃圾/位置可能是冲突的.
>更改了一些我认为可能相关的不同的Rails选项.实际上,如果我在test.rb env文件中设置config.cache_classes为false,它解决了这个问题,尽管这个规范的运行速度要慢5倍.

这是我正在运行的规范：

require 'spec_helper'

feature 'Locations',js: true,strategy: :truncation,slow: true do

  before do
    login_for_request
    Factory.create(:warehouse,code: "TW",name: 'TEST WAREHOUSE')
  end

  scenario "Creating locations" do
    visit em_locations_path
    click_link "create-locations"
    select 'TEST WAREHOUSE',from: "warehouse"
    select "GLD",from: "section"
    fill_in "row-start",with: "AA"
    fill_in "row-end",with: "AB"
    fill_in "bay-start",with: "1"
    fill_in "bay-end",with: "2"
    fill_in "tier-start",with: "1"
    fill_in "tier-end",with: "2"
    fill_in "subbay-start",with: "1"
    fill_in "subbay-end",with: "2"
    click_button "Create"
  end


end

解决方法

我想出了一个可能的解决方案来解决这个问题.这可能不是最好的方法,我不认为这是必要的,但是它的作品和作品一贯.

在我的功能规格中,我需要相关的控制器：

require_relative '../../app/controllers/locations_controller'

还需要在控制器中要求active_model_serializer：

require_relative '../serializers/location_serializer'

我当然欢迎更好的解决方案.在此期间,我的规格正在过去.
