Question

所以我对Factory Girl有一个问题，我一直在使用它，这是我第一次遇到这个问题的Rails应用程序。基本上发生的事情是当我在控制台中使用它时，它崩溃了消息/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)和一个完全由gem库组成的回溯。当我去测试时，它也失败了。在spec/support/factory_girl.rb中的测试初始化程序支持目录中，我包含了适当的代码，用于对我一直使用DatabaseCleaner进行的工厂进行lint：

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

这会在运行测试时导致错误：/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)

当我第一次使用Factory Girl方法时删除该文件时会抛出一个新错误：

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

-

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

我以前从未见过'引发：错误重新输入的消息'，但它看起来很神秘。 Factory Girl的版本是4.5，Rails版本4.2.5，RSpec版本3.4。我刚开始使用这个应用程序，所以应用程序没有很多其他代码，但这里是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

我发现了这个问题。在我的工厂里，我引用了一个有很多符号的关联，它只能在属于一边。虽然不是一个很好的错误信息。

团队不应该有关联线。
