工廠女孩崩潰測試和控制檯

所以我有一個工廠女孩的問題，我一直在使用它很多，這是我有這個問題的第一個Rails應用程序。基本上，當我在控制檯中使用它時，會發生消息/home/vagrant/.rbenv/versions/2.2.0/lib/ruby/gems/2.2.0/gems/pry-0.10.3/lib/pry/last_exception.rb:54:in 'bt_source_location_for': undefined method '[]' for nil:NilClass (NoMethodError)和完全由gem庫組成的回溯。當我去測試時，它也失敗了。在spec/support/factory_girl.rb測試初始化支持目錄我包括相應的代碼以皮棉工廠，我總是做DatabaseCleaner：工廠女孩崩潰測試和控制檯

RSpec.configure do |config| 
    config.before(:suite) do 
    begin 
     DatabaseCleaner.start 
     FactoryGirl.lint 
    ensure 
     DatabaseCleaner.clean 
    end 
    end 
end

這將導致當測試運行錯誤：/home/vagrant/.rbenv/versions/2.2.0/lib/ruby/gems/2.2.0/gems/spring-1.6.3/lib/spring/application.rb:271:in 'ensure in block (2 levels) in shush_backtraces': undefined method 'reject!' for nil:NilClass (NoMethodError)

當我刪除提交新的錯誤被拋出，當我第一次去使用工廠女孩方法：

ActiveRecord::Base.transaction do 
    create(:team) 
end

NoMethodError: undefined method `reject!' for nil:NilClass 
--- Caused by: --- 
fatal: 
    exception reentered

我以前從來沒有見過'引起錯誤重新進入的消息'，但它看起來很神祕。 Factory Girl的版本是4.5，Rails版本是4.2.5，RSpec版本是3.4。我剛開始這個應用程序，所以應用程序沒有太多的其他代碼，但這裏是rails helper，spec helper和Gemfile。

rails_helper.rb

# This file is copied to spec/ when you run 'rails generate 
rspec:install' 
ENV['RAILS_ENV'] ||= 'test' 
require File.expand_path('../../config/environment', __FILE__) 
# Prevent database truncation if the environment is production 
abort("The Rails environment is running in production mode!") if Rails.env.production? 
require 'spec_helper' 
require 'rspec/rails' 
require 'shoulda/matchers' 
require 'simplecov' 
SimpleCov.start 'rails' 

include ActionDispatch::TestProcess 
Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f } 
ActiveRecord::Migration.maintain_test_schema! 

RSpec.configure do |config| 
    config.use_transactional_fixtures = true 
    config.infer_spec_type_from_file_location! 
end

spec_helper.rb

require 'paperclip/matchers' 
require 'devise' 

RSpec.configure do |config| 
    config.include Paperclip::Shoulda::Matchers 

    config.expect_with :rspec do |expectations| 
    expectations.include_chain_clauses_in_custom_matcher_descriptions = true 
    end 

    config.mock_with :rspec do |mocks| 
    mocks.verify_partial_doubles = true 
    end 
end

的Gemfile

source 'https://rubygems.org' 

gem 'coffee-rails', '~> 4.1.0' 
gem 'devise' 
gem 'jbuilder', '~> 2.0' 
gem 'jquery-rails' 
gem 'jwt' 
gem 'paperclip', '~> 4.3' 
gem 'pg', '~> 0.15' 
gem 'rails', '~> 4.2.5' 
gem 'sass-rails', '~> 5.0' 
gem 'turbolinks' 
gem 'uglifier', '>= 1.3.0' 
gem 'unicorn' 

group :test, :development do 
    gem 'dotenv-rails' 
    gem 'bullet' 
    gem 'did_you_mean', '~> 0.10.0' 
    gem 'factory_girl_rails' 
    gem 'pry-rails' 
    gem 'rspec-rails' 
end 

group :test do 
    gem 'database_cleaner' 
    gem 'shoulda-matchers', require: false 
    gem 'simplecov', :require => false 
end 

group :development do 
    gem 'active_record_query_trace' 
    gem 'better_errors' 
    gem 'binding_of_caller' 
    gem 'spring' 
    gem 'spring-commands-rspec' 
end

我發現這個問題。在我的工廠中，我引用了一個來自許多符號的關聯，它只應該屬於一方。雖然這不是一個很好的錯誤消息。

FactoryGirl.define do 
    factory :user do 
    association :team 
    end 

    factory :team do 
    association :user 
    end 
end 

class User < ActiveRecord::Base 
    belongs_to :team 
end 

class Team < ActiveRecord::Base 
    has_many :users 
end

該團隊不應該有關聯行。
