I am trying to map list of JSON to my model but one of my model property is enum but from the JSON I am getting that property as a sting so, how can map that string as a enum
My enum -
export enum Status {
HIGH = "High",
MEDIUM = "Medium",
LOW = "Low"
}
My model -
import { Status } from "../enums/status.enum";
export class OrderModel {
id: number;
notification: string;
action: string;
status: Status ;
}
My json -
[
{
"id": 1,
"notification": "Order has ben packed",
"action": "Assign to delivery",
"status": "High"
}
]
Here I am trying to map the JSON to my model but getting the error ( Type 'string' is not assignable to type 'Status' ) -
import { OrderModel } from '../../models/order.model';
import orderData from '../json/order.json';
@Injectable({
providedIn: 'root'
})
export class OrderService{
//Here mapping JSON data to my model
orderModel: OrderModel[] = orderData;
constructor() {}
getOrderStatus() {
console.log(orderModel)
}
}
You'll need to mutate your incoming model to get the enum key. Interesting thing about TypeScript enums is that they are reverse-mappable. Therefore if you map your incoming data to your actual class you can use the value to look up the enum key.
orderModel: OrderModel[] = orderData.map(e => ({
...e,
status: Status[e.status],
}));
