Question

在修订版12之前，我只需执行以下操作即可创建一个对象，并且它与“hasMany”关系相关联

  test("findMany generates http ...", function() {
    store.load(Person, {id: 9, name: "Toran Billups", tasks: [1, 2]});
    person = store.find(Person, 9);
    expectLoaded(person);

    equal(ajaxUrl, undefined, "no Ajax calls have been made yet");

    var tasks = get(person, 'tasks');

    equal(get(tasks, 'length'), 2, ""); //this now fails showing 0 tasks ...
  });

但升级后，“任务”似乎是0而不是2，正如我所期望的那样。

以下是模型，如果这有任何帮助

  var attr = DS.attr, hasMany = DS.hasMany, belongsTo = DS.belongsTo;

  Person = DS.Model.extend({
    name: attr('string')
  });

  Task = DS.Model.extend({
    name: attr('string'),
    isFinished: attr('boolean'),
    owner: belongsTo(Person)
  });

  Person.reopen({
    tasks: hasMany(Task)
  });

我知道在加载几个任务后我可以做一个简单的“pushObject”，但我上面测试的目的是验证$ .ajax行为，当我只关联任务ID时，ember-data会获取其余的模型（延迟加载）。是否有可能像我在第12版中所说的那样保留它？

看起来你需要按照预期在版本12 -works中使用“loadHasMany”选项！

  test("findMany generates http ...", function() {
    store.load(Person, {id: 9, name: "Toran Billups"});
    person = store.find(Person, 9);
    store.loadHasMany(person, 'tasks', [ 1, 2 ]);
    expectLoaded(person);

    equal(ajaxUrl, undefined, "no Ajax calls have been made yet");

    var tasks = get(person, 'tasks');

    equal(get(tasks, 'length'), 2, ""); //this actually returns 2 :)
  });
