我可以将此回调结果与Backbone一起使用吗

Question

我希望有人能帮助我，因为我已经尝试了一个多星期，看看我是否可以使用这个回调结果来填充主干模型/集合。

具体来说，我想列出区域名称和区域GUID——我还想从PriceMatrix中获得总价。

抛开PriceMatrix不谈——我甚至会选择Area Name和AreaGUID，因为我希望学习如何遍历这个JSON，并从它的嵌套值中创建集合。

Answer 1

您可以有这样一个简单的分层设计。。。

var RootModel = Backbone.Model.extend({
default:
    {
        "CustomCallback": "",
        "ErrorDescription": "",
        "EvalMe": "",
        "HasError": false,
        "Result": null
    }
});
var ResultModel = Backbone.Model.extend({
default:
    {
        "__type": "",
        "Areas": []
    }
});
var AreaCollection = Backbone.Collection.extend({
    model: areaDetailsModel
});
var AreaDetailsModel = Backbone.Model.extend({
default:
    {
        "Area": null,
        "AreaMap": null,
        "Connector": null
    }
});
var AreaModel = Backbone.Model.extend({
default:
    {
        "AreaGuid": "",
        "AreaMapGuid": "",
        "DefaultSeatingType": 0,
        "GADefaultSettings": null,
        "Name": "",
        "NameForReports": "",
        "Ordinal": 0,
        "ParentHallGuid": "",
        "StandId": null,
        "StandName": null
    }
});
var AreaMapModel = Backbone.Model.extend({
default:
    {
        "AreaMapGuid": "",
        "DescriptionLevel": "",
        "GASettings": null,
        "GateCombinations": null,
        "IncludedInMultipleVersions": false,
        "Name": "",
        "NumberOfSeats": 0,
        "ParentAreaGuid": "",
        "SeatingType": 0,
        "Sectors": null,
        "Status": 0,
        "TurnstileCombinations": null,
        "PriceLevelIds": []
    }
});

然后，您可以将回调结果分配给rootModel。

var rootModel= new RootModel("your callback to JSON");
var resultModel = new ResultModel(rootModel.get("Result"));
var areas = new AreaCollection(resultModel.get("Areas"));
var areaDetail = areas.at(0);
var area = new AreaModel(areadetail.get("area");

Answer 2

我还没有尝试过，但这可能会奏效。

var area_detail_model = Backbone.Model.extend({
  defaults: {
    AreaGuid: null,
    AreaMapGuid: null
  }
});
var area_map_model = Backbone.Model.extend({
  defaults: {
    AreaMapGuid: null,
    DescriptionLevel: null
  }
});
var area_model = Backbone.Model.extend({
  defaults: {
    Area: new area_detail_model(),
    AreaMap: new area_map_model(),
    Connector: [] // can declare a model for connector also
    DependencyTags: [] // when using an array we can write bb_obj.get('Attr').ArrayItemName
  },
  parse : function(response){
    // at this point only area models exist, i.e from area collection each area model
    // is passed to this parse method
    response.Area =  new area_model(response.Area);
    response.AreaModel =  new area_map_model(response.AreaModel);
    return response;
  }
});
var area_collection = Backbone.Collection.extend({
  model: area_model,
  url: '/Areas',
  parse : function(response){
    return response; // place a break point and check out the contents of response
  }
});
var result_model = Backbone.Model.extend({
  defaults: {
     Areas: new area_collection(),
     Id: null,
     Pricing: null,
  },
  url: '/GetResults',
  parse : function(response){
    response.Result.Areas = new area_collection(response.Result.Areas);
    return response.Result; // this will return only the Result section from your JSON
  }
});
var result_obj = new result_model();
result_obj.fetch();

因此，当获取响应时，result_model解析函数将只从JSON中选择result，然后我们在这些区域中创建一个集合，并按顺序调用每个集合和方法的相应解析。如果有效，请告诉我。
