Ruby-on-rails 工厂已注册：用户（FactoryGirl::DuplicateDefinitionError）

Factory already registered: user (FactoryGirl::DuplicateDefinitionError)

提问by user1212241

Description of problem:- I've setup factory_girl_rails however whenever I try and load a factory it's trying to load it multiple times.

问题描述：- 我已经设置了 factory_girl_rails 但是每当我尝试加载工厂时，它都会尝试多次加载。

Environment:
- rails (3.2.1)
- factory_girl (2.5.2)
- factory_girl_rails (1.6.0)
- ruby-1.9.3-p0 [ x86_64 ]

> rake spec --trace
** Execute environment
-- Creating User Factory
-- Creating User Factory
rake aborted!
Factory already registered: user

The only other thing I've changed is: /config/initializers/generator.rb

我唯一改变的另一件事是：/config/initializers/generator.rb

Rails.application.config.generators do |g|
  g.test_framework = :rspec
  g.fixture_replacement :factory_girl
end

GEMFILE

gem 'rails', '3.2.1'

# Bundle edge Rails instead:

end

gem 'refinerycms-inventories', :path => 'vendor/engines'

FactoryGirl.define do
  factory :role do
    title "MyString"
  end
end

This seems to be a compatibility/environment issue that I can't seem to figure out. Any suggestions?

这似乎是我似乎无法弄清楚的兼容性/环境问题。有什么建议？

EDIT: here's my spec/spec_helper.rb:

编辑：这是我的规范/spec_helper.rb：

ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'
#require 'factory_girl_rails'

# Requires supporting ruby files with custom matchers and macros, etc,
# in spec/support/ and its subdirectories.
Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

RSpec.configure do |config|
### Mock Framework
  #
  # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
  #
  # config.mock_with :mocha
  # config.mock_with :flexmock
  # config.mock_with :rr

  # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
  #config.fixture_path = "#{::Rails.root}/spec/fixtures"

  # If you're not using ActiveRecord, or you'd prefer not to run each of your
  # examples within a transaction, remove the following line or assign false
  # instead of true.
  config.use_transactional_fixtures = true

  # If true, the base class of anonymous controllers will be inferred
  # automatically. This will be the default behavior in future versions of
  # rspec-rails.
  config.infer_base_class_for_anonymous_controllers = false
end

The gem factory_girl_railsshould be required in the spec_helper.rbrather than the gemfile - it is possible that you are requiring FactoryGirl twice which is why you are getting the duplicate.

factory_girl_rails应该在gem 文件中spec_helper.rb而不是在 gemfile 中需要 gem - 您可能需要两次 FactoryGirl，这就是为什么您会得到重复的原因。

Try this in your gem file:

在你的 gem 文件中试试这个：

group :test do
  gem "rspec"
  gem 'factory_girl_rails', :require => false
end

Then make sure that factory girl is required in the spec_helper with:

然后确保在 spec_helper 中需要工厂女孩：

require 'factory_girl_rails'

By the way - you don't need both rspecand rpsec-railsin your gemfile. You can replace both with the following:

顺便说一句 - 您不需要在您的 gemfile 中同时使用rspec和rpsec-rails。您可以将两者替换为以下内容：

group :development, :test do
  gem 'rspec-rails'
end

You need rspec in both groups so that the rake tasks will work in development and the core testing will work in test.

您在两个组中都需要 rspec，以便 rake 任务将在开发中工作，核心测试将在测试中工作。

I had the same problem recently. In my case one of the files in /factories had a _spec.rb ending (result of creative cp use). It was loading twice, first by rspec and then as a factory.

我最近遇到了同样的问题。在我的例子中， /factories 中的一个文件有一个 _spec.rb 结尾（创造性 cp 使用的结果）。它加载了两次，首先是通过 rspec 加载，然后是作为工厂加载。

I had this problem too. In my case there were two files with the same code, like this:

我也有这个问题。就我而言，有两个文件具有相同的代码，如下所示：

FactoryGirl.define do
  factory :user do
  end
end

One file was named "Useres.rb" and the other "User.rb" so I just deleted "Useres.rb" and fixed the error.

一个文件名为“Useres.rb”，另一个名为“User.rb”，所以我删除了“Useres.rb”并修复了错误。

Is there any chance you pasted this wholesnippet for the support file from the config docs?

您是否有机会从配置文档中粘贴整个支持文件的片段？

# RSpec
# spec/support/factory_girl.rb
RSpec.configure do |config|
  config.include FactoryGirl::Syntax::Methods
end

# RSpec without Rails
RSpec.configure do |config|
  config.include FactoryGirl::Syntax::Methods

  config.before(:suite) do
    FactoryGirl.find_definitions
  end
end

If you read the comments you'll see you only want one block or the other. I made this mistake and got the error stated in the question.

如果您阅读评论，您会发现您只想要一个或另一个。我犯了这个错误并得到了问题中所述的错误。

回答by Moriarty

Call FactoryGirl.define(:user)or FactoryGirl.find_definitionstwice you also have this problem.

打电话FactoryGirl.define(:user)或FactoryGirl.find_definitions两次你也有这个问题。

Try removing the second callor:

尝试删除第二个电话或：

FactoryGirl.factories.clear
FactoryGirl.find_definitions  

回答by Denis Kreshikhin

Another possible reason is spare call of FactoryGirl.find_definitions. Try to remove find_definitions if found.

另一个可能的原因是FactoryGirl.find_definitions. 如果找到，请尝试删除 find_definitions。

回答by scarver2

Make sure your individual factory files are not ending with _spec.

确保您的个人工厂文件不以_spec.

Loading factory girl into a development console will do this too:

将 factory girl 加载到开发控制台也将执行此操作：

require 'factory_girl_rails'; reload!; FactoryGirl.factories.clear; FactoryGirl.find_definitions

will raise a FactoryGirl::DuplicateDefinitionErroron a sequence under Factory Girl v4.4.0.

将FactoryGirl::DuplicateDefinitionError在 Factory Girl v4.4.0 下的序列上引发。

It seems the sequences get handled differently within FG and simply wrapping all sequences in a rescue block will solve the issue.

似乎序列在 FG 中的处理方式不同，只需将所有序列包装在救援块中即可解决问题。

For example:

例如：

  begin
    sequence :a_sequence do |n|
      n
    end
    sequence :another_sequence do |n|
      n*2
    end
  rescue FactoryGirl::DuplicateDefinitionError => e
    warn "#{e.message}"
  end

I had exactly the same problem. It occurs when you use the scaffold generator. It automatically creates a factory in test/factories/ So generally just deleting this file solve your issue

我遇到了完全相同的问题。当您使用脚手架生成器时会发生这种情况。它会自动在 test/factories/ 中创建一个工厂，因此通常只需删除此文件即可解决您的问题

I had the same problem, it turned out there was a default users.rbcreated inside the test/factorieswhich was created by the rails gcommand. This file was causing the conflict. The error went away when I deleted the file.

我遇到了同样的问题，原来users.rb在里面test/factories创建了一个默认值，它是由rails g命令创建的。该文件导致了冲突。当我删除文件时，错误消失了。
