CoffeeScript将对象映射到类实例

Question

Is there any way to map object received from server as a JSON to class instance in CoffeeScript?

I have a lot of cases where my JSON is:

{
  id:   '123'
  name: 'wojtek'
  age:  24
}

and my coffee class is:

class Person
    constructor: (id, name, age) ->

How to directly map JSON to class instance without assigning each property separately?

Answer 1

I would suggest rewriting your constructor to accept a single object, eg:

class Person
  constructor: (@props) ->

or

class Person
  constructor: ({@id, @name, @age}) ->

After that you'll be able to map your JSON to class instance simply by passing it to the constructor:

person = new Person data
