如何正确设置和使用factory_girl_rails？

Question

我想我在使用rails配置FactoryGirl时遇到问题。我最初遵循ASCIIcasts #275: how i test，但耙给我NameError: uninitialized constant ...

我错过了什么吗？有可能某些配置文件是错误的吗？我对RSpec和Rails很新。

我使用的Rails 3.2.2 + Mongoid + RSpec的 + factory_girl_rails。

错误：

Failures: 

    1) User should save user with valid required fields 
    Failure/Error: let(:user) { FactoryGirl.build(:valid_user) } 
    NameError: 
     uninitialized constant ValidUser 
    # ./spec/models/user_spec.rb:4:in `block (2 levels) in <top (required)>' 
    # ./spec/models/user_spec.rb:7:in `block (2 levels) in <top (required)>' 

规格/ factories.rb

FactoryGirl.define do 
    factory :valid_user do 
    name  'somename' 
    email 'a@b.com' 
    password 'somepassword' 
    end 
end 

规格/型号/ user_spec.rb

require 'spec_helper' 

describe User do 
    let(:user) { FactoryGirl.build(:valid_user) } 

    it "should save user with valid required fields" do 
    user.should be_valid 
    end 
end 

规格/ spec_helper.rb

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

Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f} 

RSpec.configure do |config| 
    config.infer_base_class_for_anonymous_controllers = false 

    config.include FactoryGirl::Syntax::Methods 
end

它通常是很有帮助的输出整错误，或至少整个第一句话 - 你还没有告诉我们缺少的常量是什么！

更新：谢谢你的整个错误。当您定义工厂：valid_user时，Factory Girl将自动假定它是针对名为ValidUser的型号。为了解决这个问题，你可以命名你的工厂:user（假设你有一个User模型），或者你可以尝试：

FactoryGirl.define do 
    factory :valid_user, :class => User do 
    name  'somename' 
    email 'a@b.com' 
    password 'somepassword' 
    end 
end 

另外，如果你想有几个不同类型的用户工厂，你可以使用方法：

FactoryGirl.define do 
    factory :user do 
    # set some attrs 
    end 

    factory :valid_user, :parent => :user do 
    name  'somename' 
    email 'a@b.com' 
    password 'somepassword' 
    end 

    factory :invalid_user, :parent => :user do 
    # some other attrs 
    end 
end

你可以声明厂这样........

Factory.define :organization do |g| 
    g.name 'Test Organization' 
    g.phone_number '5345234561' 
    g.website_url 'www.testorg.com' 
    g.city 'chichago ' 
    g.association :state 

end 

而在这样的organization_spec使用它.....

require 'spec_helper' 

describe Organization do 
    before :each do 
    @state = Factory :state 
    @organization = Factory :organization ,:state => @state 
    end 

    it "should be invalid without a name" do 
    @organization.name = nil 
    @organization.should_not be_valid 
end 

end
