Backbone一对一关系，如何获取父模型数据？

Question

exampleData = {
    id: 1,
    name: 'A',
    house: {
        address1: 'California'
        address2: 'California'
    }
}

House = Backbone.RelationalModel.extend({
    urlRoot: function urlRoot() {
        var personId = this.get('person').id; // this.get('person') is null

    }
});


Person = Backbone.RelationalModel.extend({
    relations: [
        { // Create a (recursive) one-to-one relationship
            type: Backbone.HasOne,
            key: 'house',
            relatedModel: House,
            reverseRelation: {
                type: Backbone.HasOne,
                key: 'person'
            }
        }
    ],

    initialize: function() {
    }
});

我需要获取House模型中人物的模型数据，

但是this.get('person')returns null，即使我设置了reverseRelation。

我认为您的代码无法运行。模型的定义有点错误。当你定义关系时，它应该是对对象的引用，而不是字符串值：

relatedModel: House // instead of 'House' as a string

然后你可以通过 getters 来引用每个模型，例如：

houseModel.get("person");
personModel.get("house");
