javascript - Managing models relations in AngularJS

Question

how you manage models relations with AngularJS? It is very easy in Ember, but how to deal with it in AngularJS and not produce bunch of messy code?

Answer 1

我使用https://github.com/klederson/ModelCore/它非常简单易用

var ExampleApp = angular.module('ExampleApp', ['ModelCore']); //injecting ModelCore

ExampleApp.factory("Users",function(ModelCore) {
  return ModelCore.instance({
    $type : "Users", //Define the Object type
    $pkField : "idUser", //Define the Object primary key
    $settings : {
      urls : {
        base : "http://myapi.com/users/:idUser",
      }
    },
    $myCustomMethod : function(info) { //yes you can create and apply your own custom methods
        console.log(info);
    }
  });
});

然后我只需要注入我的控制器并使用它

function MainCrtl($scope, Users) {
  //Setup a model to example a $find() call
  $scope.AllUsers = new Users();

  //Get All Users from the API
  $scope.AllUsers.$find().success(function() {
    var current;
    while(current = $scope.AllUsers.$fetch()) { //fetching on masters object
      console.log("Fetched Data into Master Object",$scope.AllUsers.$toObject()) //reading fetched from master
      //or just get the fetched object itself
      console.log("Real fetched Object",current.$toObject())
    }
  });

Angular 没有像 ember-data 这样的“数据存储”层，但如果您愿意，可以集成任何现有的 ORM -哪些选项可用于客户端 JavaScript ORM？
