Question

我正在试图弄清楚为什么这个唯一性选项会失败并且已经用尽所有选项。任何人都知道为什么这可能会在rspec中出错？

非常感谢，

这是user.rb代码，看起来这个问题源自..

 class User < ActiveRecord::Base
  attr_accessible :name, :email

  email_regex = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i

  validates :name,  :presence => true,
                    :length   => { :maximum => 50 }
  validates :email, :presence => true,
                    :format   => { :with => email_regex }
                    :uniqueness => { :case_sensitive => false }
end

Answer 1

您确定您的语法如下validates :name, :uniqueness => { :case_sensitive => false }吗？你有没有忘记'，'？或者使用符号以外的东西？

（编辑对应代码发布）

验证器之间需要逗号，如此

validates :email, :presence => true,
                :format   => { :with => email_regex }, # notice the comma after the hash
                :uniqueness => { :case_sensitive => false }
