定制装置在黄瓜中失败

Question

我已将字段添加到我的设计用户模型（全名和用户名）。这是我的用户模型：

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :token_authenticatable, :lockable, :timeoutable, :confirmable and :activatable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable  

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :username, :fullname
  # attr_accessor :username, :fullname
end

devise 工作正常，我可以在我的视图中访问全名。但黄瓜在以下情况下失败：

Scenario Outline: Creating a new account
    Given I am not authenticated
    When I go to register # define this path mapping in features/support/paths.rb, usually as '/users/sign_up'
    And I fill in "user_email" with "<email>"
    And I fill in "user_password" with "<password>"
    And I fill in "user_password_confirmation" with "<password>"
    And I fill in "user_fullname" with "<fullname>"
    And I fill in "user_username" with "<username>"
    And I press "Sign up"
    Then I should see "Signed in as <fullname>" 

    Examples:
      | email           | password   | fullname | username |
      | [email protected] | secretpass | man net | net |
      | [email protected]     | fr33z3     | foo bar | foo |

出现此错误：

...
Then I should see "Signed in as <fullname>"                                                                # features/step_definitions/web_steps.rb:108

    Examples: 
      | email           | password   | fullname | username |
      | [email protected] | secretpass | man net  | net      |
      undefined method `fullname' for #<User:0x1057a62e0> (ActionView::Template::Error)
      /Library/Ruby/Gems/1.8/gems/activemodel-3.0.3/lib/active_model/attribute_methods.rb:364:in `method_missing'
...

在模型中取消注释

attr_accessor :username, :fullname

使黄瓜可以工作，但在我看来，我无法再访问属性全名 - 我做错了什么？

更新：黄瓜不会产生错误，但测试失败，因为全名未插入数据库：

我使用rails 3.0.3和最新的黄瓜/水豚宝石，

谢谢您的帮助！

Answer 1

您正在 attr_accessible 列表中定义 fullname 字段，但从表面上看，您的 users 表中没有 fullname 字段，它也没有列在任何 attr_accessor 调用中，就像您注释掉的调用一样。

因此，未定义的方法。

Answer 2

好的，谢谢。我想我发现了问题：我使用了黄瓜功能/...，它不适用于我的迁移。

使用耙黄瓜效果很好。现在黄瓜功能/...也起作用了！？
