Question

我有以下验证：

validates :password, :presence => true, :confirmation => true, :length => { :within => 6..40 }, :format => { :with => pass_regex }, :unless => :nopass?

然后，当我尝试更新时没有密码（nopass？为真）时会出现以下错误：

There were problems with the following fields:

Password is too short (minimum is 6 characters)
Password is invalid

请注意：除非适用于：在线和：确认但不在：lenght或：format。

我该如何解决这个问题？

Answer 1

我也遇到了一些奇怪的问题：确认标志，我从未想过，但这就是我在Rails 3.0.x应用程序中解决问题的方法：

attr_accessor :password_confirmation

validates :password, :presence => true, :length => {:within => PASSWORD_MIN_LENGTH..PASSWORD_MAX_LENGTH}

validate :password_is_confirmed

  def password_is_confirmed
 if password_changed? # don't trigger that validation every time we save/update attributes
  errors.add(:password_confirmation, "can't be blank") if password_confirmation.blank?
  errors.add(:password_confirmation, "doesn't match first password") if password != password_confirmation
 end
end

我意识到这并不能解释为什么你的代码无效，但是如果你正在寻找一个快速的临时修复 - 我希望这会有所帮助。

您可以使用conditional validations

class Person < ActiveRecord::Base
  validates :surname, :presence => true, :if => "name.nil?"
end
