I'm currently trying to implement mapping to my models and the current way I'm doing it isn't yielding any result. I have a MediaLibrary class that holds 2 arrays, 'exerciseMedia' and 'stretchMedia' that both hold an array of 'Media' objects. I've opted for the ObjectMapper/AlamofireObjectMapper library to map data to my models.
import ObjectMapper
class MediaLibrary: Mappable {
var exerciseMedia: [Media]?
var stretchMedia: [Media]?
required init?(map: Map) {
mapping(map: map)
}
func mapping(map: Map) {
exerciseMedia <- map["ExerciseMedia"]
stretchMedia <- map["StretchMedia"]
}
}
Here is the Media object that will make up the objects populating both of my arrays in MediaLibrary class.
import ObjectMapper
struct Media: Mappable {
var _id: String?
var name: String?
var desc: String?
var imageURI: String?
var videoURI: String?
var trainerID: String?
var isShoulders : Bool?
var isNeck : Bool?
var isLegs : Bool?
var isHands : Bool?
var isChest : Bool?
var isCalves : Bool?
var isButt : Bool?
var isBack : Bool?
var isArms : Bool?
var isCore : Bool?
var isFullBody : Bool?
var isLowerBody : Bool?
var isUpperBody : Bool?
var isExercise : Bool?
var isStretch : Bool?
var equipmentNeeded : String?
init?(map: Map){ }
mutating func mapping(map: Map) {
_id <- map["_id"]
name <- map["name"]
desc <- map["desc"]
imageURI <- map["imageURI"]
videoURI <- map["videoURI"]
trainerID <- map["trainerID"]
isShoulders <- map["isShoulders"]
isNeck <- map["isNeck"]
isLegs <- map["isLegs"]
isHands <- map["isHands"]
isChest <- map["isChest"]
isCalves <- map["isCalves"]
isButt <- map["isButt"]
isBack <- map["isBack"]
isArms <- map["isArms"]
isCore <- map["isCore"]
isFullBody <- map["isFullBody"]
isLowerBody <- map["isLowerBody"]
isUpperBody <- map["isUpperBody"]
isExercise <- map["isExercise"]
isStretch <- map["isStretch"]
equipmentNeeded <- map["equipmentNeeded"]
}
}
Now here is a sample of the json I'm trying to map. Note my model has both 'imageURI' and 'videoURI' as there are 2 types of Media objects but since they're optionals it can account for this.
{
"StretchMedia": [
{

],
"ExerciseMedia": [

}
],
}
The problem I'm having is how to populate the 2 arrays on my MediaLibrary class with the contents of "ExerciseMedia" and "StretchMedia" to their respective arrays. I've created a function that makes a request (the body only needs the trainer id) to the route that contains the JSON you just saw. I'll post my code so far.
import AlamofireObjectMapper
var mediaLibrary: MediaLibrary?
func setTrainerMediaLibrary(trainerID: String) {
let body: [String: Any] = [
"trainerID": trainerID
]
Alamofire.request(TRAINER_MEDIA_ALL, method: .post, parameters: body, encoding: JSONEncoding.default, headers: HEADER).responseObject { (response: DataResponse<MediaLibrary>) in
if response.result.error == nil {
self.mediaLibrary = Mapper<MediaLibrary>().map(JSONObject: response.result.value)
} else {
print("Could not map JSON data to Media Library model")
debugPrint(response.result.error as Any)
}
}
}
The MediaLibrary object returns nil so something isn't right. My thoughts are that since the MediaLibrary has mapping for both "ExerciseMedia" and "StretchMedia" that all I need to do is use the MediaLibrary in the request and the mapping function will automatically handle the 2 media keys you see in the JSON. I could be going about this completely wrong but I know I'm close, any help would be appreciated.
