Attempt at utilizing decodable - json

Question

I am trying to create decodable structs for the JSON that I am receiving, but I keep getting:
keyNotFound(CodingKeys(stringValue: "inquiry_quantity", intValue: nil), Swift.DecodingError.Context(codingPath: [CodingKeys(stringValue: "orders", intValue: nil), _JSONKey(stringValue: "Index 0", intValue: 0)], debugDescription: "No value associated with key CodingKeys...
This is the JSON that I am running through my decoder:
{
"orders_important": 2,
"orders_inquiry": 2,
"orders": [
{
"information": {
"total_price": 12.0,
"order_stage": "CONFIRMED",
"total_cases": 333,
"scanned": false,
"inquiry": false,
"foodhub": "shdw.fh1#agg.com",
"identifier": "GPO00024",
"delivery_date": "2019-11-04"
},
"details": {
"pack_size": "40#",
"cases": 333,
"plu_code": 12434,
"crop_plan": 1633,
"commodity": "Conventional Bananas, , 40#"
}
},
{
"information": {
"inquiree": "FARMER",
"total_price": 23.5,
"order_stage": "INQUIRY",
"inquiry_quantity": 0,
"total_cases": 56,
"scanned": false,
"inquiry": true,
"foodhub": "shdw.fh1#agg.com",
"inquiry_type": "PRICE",
"identifier": "GPO00027",
"inquiry_price": 26.5,
"delivery_date": "2019-11-05",
"inquiry_details": "You have requested $26.5 per case, instead of $23.5."
},
"details": {
"pack_size": "40#",
"cases": 12,
"plu_code": 12434,
"crop_plan": 1589,
"commodity": "Conventional Bananas, , 40#"
}
},
],
"orders_count": 4
}
My decodable structs: (EDIT: Removed Init)
struct OrderBundle: Decodable{
let orders_important : Int
let orders_inquiry:Int
let orders_count: Int
let orders: [Order]
}
struct Order: Decodable {
let inquiry_quantity : Int
let inquiry_price : Int
let inquiry_info : String
let price : Int
let cropPlan : Int
let identifier: String
let deliveryDate : String
let quantity : Int
let unit : String
let status : String
let destination : String
let commodity: String
}
And lastly calling my decoder:
let orderData = try
JSONDecoder().decode(OrderBundle.self, from: data!)
print(orderData)
I have tried it with and without the Init in my Orders and both ways I am still getting the same error.

Answer 1

The main issue is that any dictionary must be decoded to an extra struct if init(from decoder is not provided. So basically the structure of the model must be
struct OrderBundle: Decodable {
struct Information : Decodable {
struct Details : Decodable {
The complete structs are as follows, many struct members must be declared as optional and inquiryPrice is Double, not Int. convertFromSnakeCase converts the snaked_cased keys to camelCased struct members.
struct OrderBundle : Decodable{
let ordersImportant : Int
let ordersInquiry : Int
let ordersCount : Int
let orders : [Order]
}
struct Order : Decodable {
let information : Information
let details : Details
struct Information : Decodable {
let inquiryQuantity : Int?
let inquiryPrice : Double?
let inquiryInfo : String?
let price : Int?
let cropPlan : Int?
let identifier : String
let deliveryDate : String
let quantity : Int?
let unit : String?
let status : String?
let destination : String?
let commodity: String?
}
struct Details : Decodable {
let packSize : String
let cases : Int
let pluCode : Int
let cropPlan : Int
let commodity : String
}
}
And the code to decode it
let decoder = JSONDecoder()
decoder.keyDecodingStrategy = .convertFromSnakeCase
let orderData = try decoder.decode(OrderBundle.self, from: data!)
print(orderData)
