Convert json response to Realm object - json

Question

hi I am trying to convert json response from a web service to realm object and insert it into realm database using object mapper but returns objects with null values
Alamofire.request(url).responseJSON { response in
let products = Mapper<ProRealm>().map(JSONObject:response.result.value)
print("products",products) // object with null values
}
My ProRealm class is
class ProRealm: Object, Mappable {
dynamic var additives_count: String?
var rating: String?
var updated: Bool = false;
var name: String?
var barcode: String?
var product_key: String?
var hazard_count: String?
var state: String?
var no_of_users_rated: String?
var thumbnail: String?
var overall_rating : String?
var is_food_or_beverage : Bool = false
//Impl. of Mappable protocol
required convenience init?(map: Map) {
self.init()
}
func mapping(map: Map) {
additives_count <- map["additives_count"]
rating <- map["rating"]
updated <- map["updated"]
name <- map["name"]
barcode <- map["barcode"]
product_key <- map["product_key"]
hazard_count <- map["hazard_count"]
state <- map["state"]
no_of_users_rated <- map["no_of_users_rated"]
thumbnail <- map["thumbnail"]
overall_rating <- map["overall_rating"]
is_food_or_beverage <- map["is_food_or_beverage"]
}
}
In Json response, the products are inside the products key. please advice how to convert it into realm object
["kind": aWareInternalAPI#productsItem, "products":(
{
"additives_count" = 3;
barcode = 12345;
"hazard_count" = 0;
"is_food_or_beverage" = 1;
name = "Water Bottle";
"no_of_users_rated" = 1;
"overall_rating" = "0.0";
"product_key" = "ahdzfmF3YXJlLWJhY2tlbmQtc3RhZ2luZ3IlCxIEVXNlchiAgICgvoOTCQwLEgdQcm9kdWN0GICAgIDE_JAKDA";
rating = 0;
state = "OCR_PROCESSING";
thumbnail = "http://lh3.googleusercontent.com/dMxwgSQB02osZJJex4S57iupaMT9tjDYZaD7mweJUjYmI1KNEcZZe1syBwrRs1GbYdZNrRUtQwRYUwXiAEscGNYH-J9f3gJOXYO1rQ=s150";
updated = 1;
},
{
"additives_count" = 0;
barcode = 53647825898248485;
"hazard_count" = 0;
"is_food_or_beverage" = 1;

"overall_rating" = "0.0";
"product_key" = ahdzfmF3YXJlLWJhY2tlbmQtc3RhZ2luZ3IlCxIEVXNlchiAgICgvoOTCQwLEgdQcm9kdWN0GICAgICumYAJDA;
rating = "";
state = "OCR_PROCESSING";
thumbnail = "http://lh3.googleusercontent.com/0D55ZXkG8Ua5ULDK69Po-IHeDPIfXZHOi7LlLURoc1qZzmNst57xUMQSPzWTW5miSDglc5wKDA4QlvLvnD6aMOqIHcwlj_HY-Hs=s150";
updated = 1;
})]
Please advice

Answer 1

All your properties except updated and is_food_or_beverage are nilable, so there is a possibility that they might be nil. If you know that they should have a value and you´re still getting nil make sure to check the keys in your mapping function.
Update:
I´m not 100% sure of how this works with the syntax with Mappable, but you need to do it something like this:
class Products: Object, Mappable {
let products: [Product]?
//Impl. of Mappable protocol
required convenience init?(map: Map) {
self.init()
}
func mapping(map: Map) {
products <- map["products"]
}
}
class Product: Object, Mappable {
dynamic var additives_count: String?
var rating: String?
var updated: Bool = false;
var name: String?
var barcode: String?
var product_key: String?
var hazard_count: String?
var state: String?
var no_of_users_rated: String?
var thumbnail: String?
var overall_rating : String?
var is_food_or_beverage : Bool = false
//Impl. of Mappable protocol
required convenience init?(map: Map) {
self.init()
}
func mapping(map: Map) {
additives_count <- map["additives_count"]
rating <- map["rating"]
updated <- map["updated"]
name <- map["name"]
barcode <- map["barcode"]
product_key <- map["product_key"]
hazard_count <- map["hazard_count"]
state <- map["state"]
no_of_users_rated <- map["no_of_users_rated"]
thumbnail <- map["thumbnail"]
overall_rating <- map["overall_rating"]
is_food_or_beverage <- map["is_food_or_beverage"]
}
}
So create two different classes one that holds an array of products and the other is a Product.
