ruby-on-rails-3 - 导轨 3 + Rspec 2 : Validation failed: Email has already been taken

Question

我有 2 个模型，User和 Bucket . User has_many Buckets和 Bucket belongs_to一个 User .

在 factories.rb ， 我有:

Factory.define :user do |user|
  user.email  "teste@test.com"
  user.password               "foobar"
  user.password_confirmation  "foobar"
end


Factory.sequence :email do |n| 
  "person-#{n}@example.com"
end

Factory.define :bucket do |bucket|
  bucket.email        "user@example.com"
  bucket.confirmation false
  bucket.association :user
end

我有一个 login_user 模块，如下所示:

def login_user
    before(:each) do
      @request.env["devise.mapping"] = Devise.mappings[:user]
      @user = Factory.create(:user)
      #@user.confirm!
      sign_in @user
    end
  end

我正在使用 Spork 和 Watch 以及我的 Buckets_controller_spec.rb很简单:

describe "User authenticated: " do

   login_user  

   @bucket = Factory(:bucket)

   it "should get index" do
     get 'index'
     response.should be_success
   end
...
end

错误总是一样的:

Failures:

  1) BucketsController User authenticated: should get index
     Failure/Error: Unable to find matching line from backtrace
     ActiveRecord::RecordInvalid:
       Validation failed: Email has already been taken
     # ./lib/controller_macros.rb:12:in `block in login_user'

只有当我拥有 Factory(:bucket) 时才会发生这种情况.当我不添加 Factory(:bucket) 时，登录工作正常.

它总是同样的错误。我已尝试添加 :email => Factory.next(:email)给用户，但没有成功。

编辑:

在 rails c test :

ruby-1.9.2-p180 :019 > bucket = Factory(:bucket, :email => "hello@hello.com")
    ActiveRecord::RecordInvalid: Validation failed: Email has already been taken

    ruby-1.9.2-p180 :018 >   Bucket.create(:email => "hello@hello.com")
     => #<Bucket id: 2, email: "hello@hello.com", confirmation: nil, created_at: "2011-04-08 21:59:12", updated_at: "2011-04-08 21:59:12", user_id: nil> 

编辑2:

我发现错误在关联中，但是，我不知道如何解决它。

  bucket.association :user

Answer 1

当您使用关联定义工厂时，您需要为工厂提供一个对象，以便在您使用工厂时与之关联。

这应该有效:

describe "User authenticated: " do
  login_user
  @bucket = Factory(:bucket, :user => @user)

  it "should get index" do
    get 'index'
    response.should be_success
  end
end

这样，factorygirl 就知道要制作一个与@user 关联的存储桶。
