attr_accessor导致Rspec测试失败 [英] attr_accessor causes Rspec tests to fail
本文介绍了attr_accessor导致Rspec测试失败的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我已经在用户模型中添加了:username_or_email属性，如下所示:
I've added a :username_or_email property to my User model as such:
class User < ActiveRecord::Base
#authlogic
acts_as_authentic do |c|
c.login_field = :username_or_email
end
#virtual field for allowing a user to login with their username or email
attr_accessor :username_or_email
attr_accessible :username, :email, :password, :password_confirmation, :username_or_email
validates :username, :presence => true,
:length => { :within => 3..20 },
:uniqueness => true,
:format => { :with => /\A[a-z0-9][a-z0-9\-]+[a-z0-9]\z/ }
validates :email, :presence => true,
:format => { :with => /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i },
:uniqueness => { :case_sensative => false }
validates :password, :presence => true,
:confirmation => true,
:length => { :within => 6..40 }
def self.find_by_username_or_email(username_or_email)
User.find_by_username(username_or_email) || User.find_by_email(username_or_email)
end
end
此操作的目的是创建一个虚拟字段，该字段允许用户使用Authlogic以其用户名或电子邮件登录.当我运行服务器时，它完全可以完成我想要的工作，因此效果很好.但是，这会导致以下所有规格失败:
The purpose of this is to create a virtual field which allows the user to log in with either their username or email using Authlogic. This works perfectly when I run the server, doing exactly what I want it to. However, it causes all of the following specs to fail:

似乎问题出在valid?方法上，但是我不明白为什么考虑:username_or_email时没有任何验证.为什么会出现这些错误，我该如何解决?
It seems like the problem is occurring with the valid? method, but I don't understand why considering :username_or_email doesn't have any validations in place. Why are these errors occurring and how can I fix them?
谢谢.
推荐答案
该解决方案实际上非常简单.在user.rb中:
The solution was actually pretty simple. In user.rb:
class User < ActiveRecord::Base
#authlogic
acts_as_authentic do |c|
c.login_field = :username_or_email
c.validates_login_field = false
end
...
end
可以找到该方法的文档这里.
The documentation for this method can be found here.
