Ошибка циклической зависимости в Rails 4 во время запросов Rspec

У меня есть приложение, работающее на Rails 4/Ruby 2. Интерфейс разрабатывается с помощью Ember.

При запуске rake spec я получаю следующее исключение. Похоже, что это происходит только в спецификациях функций Rspec (не в режиме dev). Кроме того, это обычно происходит только в том случае, если я запускаю только одну спецификацию функции; если я запускаю весь набор тестов, я обычно не получаю ошибку.

Ошибка возникает из-за этой фиксации для Rails: https://github.com/rails/rails/commit/b33700f5580b4cd85379a1dc60fa341ac4d8deb2

Но, конечно, я не знаю, является ли эта реальная проблема или если она что-то глубже в стеке вызовов. Я действительно знаю, если я сделаю минимальное изменение в коде Rails, чтобы не выбросить эту ошибку, все работает нормально, и мои тесты проходят. Но что-то, где-то, похоже, пытается загрузить LocationsController, даже если он уже загружен.

Любая помощь очень приветствуется, так как эта у меня действительно туманная.

routes.rb:

get '/locations', to: 'main#index', :as => :em_locations

scope 'api' do
  resources :locations, only: [:index]
end

Соответствующие драгоценные камни:

  * capybara (2.1.0)
  * rspec (2.13.0)
  * rspec-core (2.13.1)
  * rspec-expectations (2.13.0)
  * rspec-mocks (2.13.1)
  * rspec-rails (2.13.2)
  * ember-data-source (0.0.5)
  * ember-rails (0.12.0)
  * ember-source (1.0.0.rc3.3)
  * active_model_serializers (0.8.1)

Что я пробовал:

  • Изменение имен и путей моих маршрутов, считая, что ember/location могут быть конфликтующими.
  • Изменено несколько различных параметров Rails, которые, как я думал, могут быть релевантными. На самом деле, если я установил config.cache_classes в false в файле test.rb env, он решает проблему, хотя за счет того, что спецификации работают примерно на 5X медленнее.

Здесь spec, который я запускаю:

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

Ответ 1

Я придумал одно возможное решение этой проблемы. Вероятно, это не самый лучший способ, и я не думаю, что это необходимо, но тем не менее оно работает и работает последовательно.

В моей спецификации спецификации мне нужен связанный контроллер:

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

В контроллере также необходимо было указать active_model_serializer:

require_relative '../serializers/location_serializer'

Я, безусловно, приветствую лучшие решения. Тем временем мои спецификации проходят.
