Rails 3 + Rspec 2:验证失败:已经收到电子邮件

Question

我有2个型号,User和Bucket.User has_many Buckets和Bucket belongs_toa 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,我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'

它只会发生在我拥有的时候Factory(:bucket).当我不添加时,登录工作正常Factory(:bucket).

它总是一样的错误.我试过添加:email => Factory.next(:email)到用户,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

使用关联定义工厂时,无论何时使用工厂,都需要为工厂提供关联的对象.

这应该工作:

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知道要制作一个与@user相关联的存储桶.

Answer 2

在您的用户工厂中尝试:

Factory.define :user do |f|
  f.sequence(:email) { |n| "test#{n}@example.com" }
  ...
end

我想这可能是你的问题.当你使用f.email = "anyvalue"它时,每次都会使用该值.我看到你试图在下一个块中创建一个序列,但我不确定序列是否被使用.

另外 - 请注意,如果您因崩溃或某些事情而中断测试,有时虚假测试数据可能会留在测试数据库中而不是回滚.

如果某些东西工作一次然后退出工作,我首先尝试重置测试数据库.

rake db:test:prepare

这将清除一切.

如果这不起作用,请告诉我,我会再看看!
