Rails 3.1,工厂女孩bug

Question

固定.Rails中有一个错误.请参阅https://github.com/rails/rails/issues/2333

我有Factory Girl Rails和Rails 3.1.0.rc5的问题

当我做不止一次时,user = FactoryGirl.create(:user)我有一个错误.

 Failure/Error: user = FactoryGirl.create(:user)
 NameError:
   uninitialized constant User::User
 # ./app/models/user.rb:17:in `generate_token'
 # ./app/models/user.rb:4:in `block in <class:User>'
 # ./spec/requests/users_spec.rb:20:in `block (3 levels) in <top (required)>'

我可以使用Factory创建尽可能多的用户,但仅限于rails控制台.

测试:

require 'spec_helper'

describe "Users" do

  describe "signin" do

    it "should sign in a user" do
      visit root_path
      user = FactoryGirl.create(:user)
      within("div#sign_in_form") do
        fill_in "Name", with: user.name
        fill_in "Password", with: user.password
      end
      click_button "Sign in"
      current_path.should eq(user_path(user))
      page.should have_content("signed in")
    end

    it "should not show new user form on /" do
      user = FactoryGirl.create(:user)
          visit root_path
      page.should_not have_css("div#new_user_form")
    end
  end
end

factories.rb

FactoryGirl.define do
  factory :user do |f|
    f.sequence(:name) { |n| "john#{n}" }
    f.fullname  'Doe'
    f.sequence(:email) { |n| "test#{n}@example.com" }
    f.password 'foobar'
  end
end

模型/ user.rb

class User < ActiveRecord::Base
  has_secure_password
  attr_accessible :name, :fullname, :email, :password
  before_create { generate_token(:auth_token) }

  email_regex = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
  validates :name, presence: true, length: { maximum: 20 },
            uniqueness: { case_sensitive: false }
  validates :fullname, presence: true, length: { maximum: 30 }
  validates :email, format: { with: email_regex },
            uniqueness: { case_sensitive: false }, length: { maximum: 30 }
  validates :password, length: { in: 5..25 }

  def generate_token(column)
    begin
      self[column] = SecureRandom.urlsafe_base64
    end while User.exists?(column => self[column])
  end
end

User.exists?(column => self[column]) 导致问题.

你的 Factory.rb 中有一行额外的内容，它应该是这样的：

FactoryGirl.define :user do |f|
  f.sequence(:name) { |n| "john#{n}" }
  f.fullname  'Doe'
  f.sequence(:email) { |n| "test#{n}@example.com" }
  f.password 'foobar'
end
