如何正确设置和使用factory_girl_rails？

Question

我认为我在使用rails配置FactoryGirl时遇到问题.我最初遵循的是ASCIIcast#275:我如何测试,但是rake正在给我NameError: uninitialized constant ...

我错过了什么吗？是否有可能某些配置文件错误？我是RSpec和Rails的新手.

我使用的Rails 3.2.2 + Mongoid + 的RSpec + 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)>'

投机/ 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

投机/ 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

输出整个错误或至少整个第一句通常是有帮助的 - 你甚至没有告诉我们缺少的常数是什么!

更新:感谢整个错误.当您定义工厂:valid_user时,Factory Girl将自动假定它适用于名为的模型ValidUser.要解决这个问题,您可以为工厂命名:user(假设您有User模型),或者您可以尝试:

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

或者,如果您想拥有几种不同类型的用户工厂,则可以使用:

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
