为什么`before_save`在Rails 4中不起作用？

When I try u = User.new followed by u.save, the before_save method is not being fired.

当我尝试u = User.new后跟u.save时，不会触发before_save方法。

Here's my User model:

这是我的用户模型：

class User < ActiveRecord::Base
  attr_accessor :password
  before_save :encrypt_password

  def encrypt_password
    puts "Its getting called"
  end
end

The callback methods need to be either protected or private.

回调方法需要是受保护的或私有的。
