我目前正在使用骨干网,我在新模型上运行获取,并从服务器获得响应,我正在获取的模型应该包含其他模型和集合,返回的JSON支持这个和它看起来像这样,
{

}
}
}
因此,在获取之后,我如何确保briefversion
成为模型并且在briefversionsections
内成为一个集合,同样如何确保组织对象的users属性也成为一个集合?
答案 0 :(得分:2)
您需要覆盖parse以便以正确的格式处理从服务器获取JSON。完成后,您可以为initialize方法中的某些属性实例化集合。
例如
initialize: function () {
this.briefversionsections = new Backbone.Collection(this.briefversionsections);
this.users = new Backbone.Collection(this.users);
},
parse: function (response, options) {
var myModel = response.briefversion;
myModel.users= response.organisations.users
return myModel;
}
