运行测试时遇到这个错误.我已经检查确保所有的email_confirmations拼写正确,(除非我疯了)他们是.我有点Rails noob,所以这可能是一件简单的事情.
用户模型
class User < ActiveRecord::Base
attr_accessible :email,:email_confirmation,:first_name,:last_name,:password,:password_confirmation
has_secure_password
before_save { |user| user.email = email.downcase }
validates :first_name,presence: true,length: { maximum: 25 }
validates :last_name,length: { maximum: 25 }
VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
validates :email,format: { with: VALID_EMAIL_REGEX },uniqueness: { case_sensitive: false }
validates :email_confirmation,presence: true
validates :password,length: { maximum: 6 }
validates :password_confirmation,presence: true
end
Rspec测试

解决方法
您收到UnknownAttributeError,因为您的用户表中没有一个名为email_confirmation的列.默认情况下,ActiveRecord将查找与您用于构建模型的属性相同的DB列,但此行正在尝试构造具有数据库不知道的属性的用户：
before { @user = User.new(email: "user@example.com",email_confirmation: "user@example.com") }
您真的打算将电子邮件确认保存在数据库中,还是只是想在保存之前检查它与电子邮件相匹配？我假设后者,而Rails实际上已经内置了支持：
class User < ActiveRecord::Base validates :email,:confirmation => true validates :email_confirmation,:presence => true end
查看有关Rails Guide to Validations或validates_confirmation_of API文档的更多详细信息. (你可能需要做同样的事情：password_confirmation.)
