关于restful_authentication密码更新问题

使用restful_authentication插件时，进行更新密码操作时，如果传来密码为空时，会发现有关密码验证空值验证会失效

 

这是因为在

by_password.rb文件中，是这样记录的

 

 

    # Stuff directives into including module
    def self.included(recipient)
      recipient.extend(ModelClassMethods)
      recipient.class_eval do
        include ModelInstanceMethods
        
        # Virtual attribute for the unencrypted password
        attr_accessor :password
        validates_presence_of     :password,                   :if => :password_required?
        validates_presence_of     :password_confirmation,      :if => :password_required?
        validates_confirmation_of :password,                   :if => :password_required?
        validates_length_of       :password, :within => 6..40, :if => :password_required?
        before_save :encrypt_password
      end
    end # #included directives

 

 

 

      def password_required?
        crypted_password.blank? || !password.blank?
      end

 

此时crypted_password存在， crypted_password.blank?返回false, 而!password.blank?也返回false

所以password空值验证就失效了

validates_presence_of :password, :if => :password_required?

 

解决这个问题可以在更新之前，把crypted_password设置成nil

 

 

@user = User.find_by_id(params[:id])
@user.crypted_password = nil
if @user.update_attributes(:password => params[:password], :password_confirmation => params[:password_confirmation])
	flash.now[:notice] = "success"
else
	flash.now[:notice] = "error"
end
