How to cleanly initialize attributes in Ruby with new?

Question

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

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


        

Answer 1

Foo = Struct.new(:name, :age, :email, :gender, :height)

This is enough for a fully functioning class. Demo:

p Foo.class # Class

employee = Foo.new("smith", 29, "smith@foo.com", "m", 1.75) #create an instance
p employee.class # Foo
p employee.methods.sort # huge list which includes name, name=, age, age= etc
