RSPEC錯誤：驗證失敗：電子郵件已經採取了Rails的教程

Question

運行測試，當我遇到這些錯誤：

1) UsersController PUT 'update' authentication of edit/update pages for non-signed-in  users should deny access to 'edit' 
    Failure/Error: @user = Factory(:user) 
    ActiveRecord::RecordInvalid: 
     Validation failed: Email has already been taken 
    # ./spec/controllers/users_controller_spec.rb:130 

    2) UsersController PUT 'update' authentication of edit/update pages for non-signed-in users should deny access to 'update' 
    Failure/Error: @user = Factory(:user) 
    ActiveRecord::RecordInvalid: 
     Validation failed: Email has already been taken 
    # ./spec/controllers/users_controller_spec.rb:130 

    3) UsersController PUT 'update' authentication of edit/update pages for signed-in users should require matching users for 'edit' 
    Failure/Error: @user = Factory(:user) 
    ActiveRecord::RecordInvalid: 
     Validation failed: Email has already been taken 
    # ./spec/controllers/users_controller_spec.rb:130 

    4) UsersController PUT 'update' authentication of edit/update pages for signed-in users should require matching users for 'update' 
    Failure/Error: @user = Factory(:user) 
    ActiveRecord::RecordInvalid: 
     Validation failed: Email has already been taken 
    # ./spec/controllers/users_controller_spec.rb:130 

    5) UsersController PUT 'update' GET 'edit' should be successful 
    Failure/Error: @user = Factory(:user) 
    ActiveRecord::RecordInvalid: 
     Validation failed: Email has already been taken 
    # ./spec/controllers/users_controller_spec.rb:168 

    6) UsersController PUT 'update' GET 'edit' should have a link to change the Gravatar 
    Failure/Error: @user = Factory(:user) 
    ActiveRecord::RecordInvalid: 
     Validation failed: Email has already been taken 
    # ./spec/controllers/users_controller_spec.rb:168 

似乎它並不喜歡這一行：

before(:each) do 
     @user = Factory(:user) 
     test_sign_in(@user) 
end 

工廠代碼

# By using the symbol ':user', we get Factory Girl to simulate the User model. 
Factory.define :user do |user| 
    user.name     "Insert Name" 
    user.email     "email@example.com" 
    user.password    "password" 
    user.password_confirmation "password" 
end 

我想這就是你想要的。

用戶控制器規格

顯示我們用戶的工廠代碼。我想你會爲每個用戶使用非唯一的電子郵件。嘗試在Factory序列的幫助下爲用戶創建電子郵件。另外，檢查你的_test db重複記錄。
