如何使用new干净地初始化Ruby中的属性? [英] How to cleanly initialize attributes in Ruby with new?

问题描述

class Foo
  attr_accessor :name, :age, :email, :gender, :height

  def initalize params
    @name = params[:name]
    @age = params[:age]
    @email = params[:email]
    .
    .
    .
  end

这似乎是一种愚蠢的做法.在Ruby中初始化对象的更好/更惯用的方法是什么?
