Rails,属性确认

我不喜欢Rails确认验证如何将“与确认不匹配”的消息附加到父属性...

validates(:password, {confirmation: true})

从UX的角度来看,当两者不匹配时,错误应传递给确认,“密码不匹配”,这更有意义。

将任何验证添加到确认属性似乎都会被忽略......

validates(:password_confirmation, {my_validation: true, length: {maximum: 3}})

** length验证仅用于测试目的。请注意,此屏幕截图中的密码确认字段没有错误:

我创建了自定义验证better_validation

class BetterConfirmationValidator < ActiveModel::EachValidator
  def validate_each(record, attr_name, value)
    parent_attr = attr_name.to_s
    parent_attr['_confirmation'] = ''
    unless value == record.send(parent_attr)
      record.errors.add(attr_name, :better_confirmation, options.merge(:value => value))
    end
  end
end

但是除非我将确认字段命名为不同(即在最后加上's'...... :password_confirmations),否则它不起作用。

有没有办法告诉Rails不要接管并让我对foo_confirmation属性进行验证?

谢谢!

修改

型号代码......

class User < ActiveRecord::Base
  attr_accessible :name, :email, :password, :password_confirmation
  attr_accessor :password, :password_confirmation

  validates :name,
    presence: true,
    length: { maximum: 50 }
  validates :email,
    presence: true,
    format: { with: /\A.+@[a-z\d\-.]+\z/i },
    uniqueness: true
  validates :password,
    length: { minimum: 6, maximum: 255 },
    presence: { on: :create }
  validates :password_confirmation,
    presence: true,
    better_confirmation: true
.
.
.
end

答案 0 :(得分:0)

尝试:

validates :password,
  presence: true,
  length: { minimum: 6, maximum: 255 },
  confirmation: true

或与此:

validate :password_confirmation_match


def password_confirmation_match
  self.errors[:password_confirmation] << "does not match password" if self.password_confirmation.to_s != self.password
end
