我已经在几个地方看到过这个问题，但似乎没有一个解决方案有效。

我有一个 Rails 3.1 应用程序，其中包含最新版本的 guard、spork、factory girl、rspec 和 devise。

每当我尝试创建用户工厂（用户模型是设计模型）时，我都会收到此错误：

Could not find a valid mapping for #<User...model attributes...>

我不确定问题是什么。

我跑了rake db:test:prepare。我遵循了这个stackoverflow问题中的说明：“找不到#<User ...>的有效映射”仅在第二次和后续测试中

另外，我在 google groups 的这个答案中尝试了解决方案：

https://groups.google.com/forum/?fromgroups#!topic/plataformatec-devise/StpbEsDCec0[1-25]

而且，这是所有相关代码：

保护文件 

    # A sample Guardfile
# More info at https://github.com/guard/guard#readme
require 'capybara/rspec'
guard 'spork', :cucumber_env => { 'RAILS_ENV' => 'test' }, :rspec_env => { 'RAILS_ENV' => 'test' } do
  watch('config/application.rb')
  watch('config/environment.rb')
  watch('config/environments/test.rb')
  watch(%r{^config/initializers/.+\.rb$})
  watch('Gemfile')
  watch('Gemfile.lock')
  watch('spec/spec_helper.rb') { :rspec }
  watch('test/test_helper.rb') { :test_unit }
  watch(%r{features/support/}) { :cucumber }
end

guard 'rspec', :version => 2, :cli => '--drb' do
  watch(%r{^spec/.+_spec\.rb$})
  watch(%r{^lib/(.+)\.rb$})     { |m| "spec/lib/#{m[1]}_spec.rb" }
  watch('spec/spec_helper.rb')  { "spec" }

  # Rails example
  watch(%r{^app/(.+)\.rb$})                           { |m| "spec/#{m[1]}_spec.rb" }
  watch(%r{^app/(.*)(\.erb|\.haml)$})                 { |m| "spec/#{m[1]}#{m[2]}_spec.rb" }
  watch(%r{^app/controllers/(.+)_(controller)\.rb$})  { |m| ["spec/routing/#{m[1]}_routing_spec.rb", "spec/#{m[2]}s/#{m[1]}_#{m[2]}_spec.rb", "spec/acceptance/#{m[1]}_spec.rb"] }
  watch(%r{^spec/support/(.+)\.rb$})                  { "spec" }
  watch('config/routes.rb')                           { "spec/routing" }
  watch('app/controllers/application_controller.rb')  { "spec/controllers" }

  # Capybara request specs
  watch(%r{^app/views/(.+)/.*\.(erb|haml)$})          { |m| "spec/requests/#{m[1]}_spec.rb" }

  # Turnip features and steps
  watch(%r{^spec/acceptance/(.+)\.feature$})
  watch(%r{^spec/acceptance/steps/(.+)_steps\.rb$})   { |m| Dir[File.join("**/#{m[1]}.feature")][0] || 'spec/acceptance' }
end
</code>

This is in my spec/factories.rb

FactoryGirl.define do   
 load "#{Rails.root}/app/models/user.rb"  
 factory :user, class: User do |user|
    email 'owner@example.com'
     password '12345678'
    password_confirmation '12345678'
     companyid 'example_company'   
  end 
end

This is my spec/controllers/api_controller_spec.rb

require 'spec_helper'

describe ApiController do
  it 'verifies company_id through POST to api/company_id' do
    load "#{Rails.root}/app/models/user.rb"
    debugger
    user = FactoryGirl.create(:user)
    post(:get_company_id, {:company_id => 'example_company'})
    response.body.should include('true')
  end
end

And I have this at the end of my config/application.rb

    ActionDispatch::Callbacks.after do
  # Reload the factories
  return unless (Rails.env.development? || Rails.env.test?)

  unless FactoryGirl.factories.blank? # first init will load factories, this should only run on subsequent reloads
    FactoryGirl.factories.clear
    FactoryGirl.find_definitions
  end
end

I'm really desperate for an answer here because otherwise I won't be able to test my User model (which is the most important model I have).

Feel free to comment and ask any questions.

EDIT: code looked funny in places, so I edited it for clarity

UPDATE:

So I tried simplifying everything to get to the core of the problem, and I'm pretty sure that devise and factory girl don't "like" each other. I'm still getting the exact same error whenever I try and create a user factory.

This is my new setup (I reverted to a previous git commit and I no longer have guard or spork).

My factories.rb is exactly the same as Michael Durant's except I have an extra line:

companyid 'example'

That's just a requirement for my app.

My spec_helper.rb requires rubygems and capybara/rspec and that's it.

And this is my spec/models/user_spec.rb

require 'spec_helper'
  describe 'User associations' do

    it 'tests creation of user' do
      debugger
      user = FactoryGirl.create(:user)
      User.count.should be(1)

    end
  end

Also, this is interesting: When I hit that debugger statement and type in 

 eval User

It shows the mapping of a valid User.

UPDATE:

So, it's not factory girl that's the problem. It's devise.

This is the new api_controller_spec.rb file and it comes up with the same error of not having a valid mapping of the user.

require 'spec_helper'

describe ApiController do
  it 'verifies company_id through POST to api/company_id' do
    load "#{Rails.root}/app/models/user.rb"
    debugger
    user = User.new
    user.email = 'owner@example.com'
    user.password = '12345678'
    user.password_confirmation = '12345678'
    user.company_id = 'company'
    user.save
    post(:get_company_id, {:company_id => 'example_company'})
    response.body.should include('true')
  end
end

任何其他环境都没有问题，因为我可以通过控制台创建用户，而本地服务器正在运行，或者代码被推送到 Heroku。它可能是 rspec 或其他东西，但我现在不确定。

我建议您简化事情以找到问题。目前我觉得你有太多的事情/太多的可变因素。

我会推荐以下内容：

1 新建一个分支。我假设您正在使用 git，如果不使用它（git init）并创建一个 fork。

2 拆下所有的叉子和护板。它们有助于加快您的测试并在 CI（持续集成）中运行测试，但它们肯定不是“需要的”，删除它们将有助于发现真正的问题。

3 正确设置您的用户工厂。我们使用这个：

FactoryGirl.define do
  sequence :email do |n| 
    "email#{n}@factory.com"
  end 

  factory :user do
    email 
    first_name            { 'First' }
    last_name             { 'Last' }
    password              { "password" }
    password_confirmation { "password" }
    association           :area
    role                  { 'super_user' }
  end 

end

4 正确设置您的 spec_help。我们在 spec_helper.rb 中使用这些需求：

require 'rubygems'
require 'capybara/rspec'

5 尝试使用 spec/models/user_spec.rb 让一个用户测试通过，例如：

require 'spec_helper'
describe 'User associations' do
subject { User.new }
it { should validate_presence_of :area }

因此，答案与guard、spork、rspec 或 factory_girl 无关。

问题是我的devise_for :users路线被注释掉了，因为我一直在对我的 rails 应用程序进行大修。

总是很简单的事情>.<
