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,我的Buckets_controller_spec.rb非常简单：

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'

它只发生在我有工厂(：桶)时.当我不添加Factory(：bucket)时,登录正常.

它总是一样的错误.我尝试过添加：email => Factory.next(：email)给用户,但没有成功.

编辑：

在rails c测试中：

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
