Alamofire, Objectmapper, Realm: Nested Objects

Question

I\'m using Alamofire, Objectmapper, Realm and everything is working beside one thing: I can\'t map nested objects.

class Voting: Object, Mappable {

    dyna         


        

Answer 1

class ListTransform : TransformType where T:Mappable {
    typealias Object = List
    typealias JSON = [AnyObject]

    let mapper = Mapper()

    func transformFromJSON(_ value: Any?) -> Object? {
        let results = List()
        if let objects = mapper.mapArray(JSONObject: value) {
            for object in objects {
                results.append(object)
            }
        }
        return results
    }

    func transformToJSON(_ value: Object?) -> JSON? {
        var results = [AnyObject]()
        if let value = value {
            for obj in value {
                let json = mapper.toJSON(obj)
                results.append(json as AnyObject)
            }
        }
        return results
    }
}

Then in your model something like this.

class Parent: Object, Mappable {
    dynamic var id: Int = 0
    var children = List()

    required convenience init?(_ map: Map) {
        self.init()
    }

    func mapping(map: Map) {
        id <- map["id"]
        child <- (map["children"], ListTransform())
    }
}
