Utilizing Angular2/TypeScript to Retrieve Class Elements within an Array Object

One interesting feature I have implemented is a class that handles single properties and arrays of other classes:

Offert Class

import {OffertRegion} from './offert-region';
import { OffertProduct } from './offert-product';

export class Offert {
    public idOffert: number;
    public OffertCode: string;

    public Regions: OffertRegion[];

    public Products: OffertProduct[];

constructor(values: Object = {}) {
        Object.assign(this, values);
    }

}

OffertRegion Class

export class OffertRegion {

    public idOffert: number;
    public idOffertRegion: number;
    public Region: string;
    public intOrder: number;

    constructor(values: Object = {}) {
        Object.assign(this, values);
    }
}

OffertProduct Class

export class OffertProduct {

    public idOffert: number;
    public OffertCode: string;
    public idOffertRegion: number;
    public Region: string;
    public intRegionOrder: number;
    public idOffertRow: number;
    public idProduct: number;
    public ProductCode: string;
    public Product: string;
    public Seats: number;
    public ImagePath: string;
    public Qty: number;

    constructor(values: Object = {}) {
        Object.assign(this, values);
    }
}

Encountering an issue during page loading where a compilation error in the console pops up:

offert-detail.component.ts (55,21): Property 'Products' does not exist on type 'Offert'.

The source of this error lies in the following code snippet:

s.subscribe(
      res => {
        console.log('header')
        console.log(res.header);
        console.log('regions')
        console.log(res.regions);
        console.log('products')
        console.log(res.products);

        this.offert = res.header;              
        this.offert.Regions = res.regions; //this is line 53

        this.offert.Products = res.products; // this is line 55!!!
      },
      error => this.errorMessage = <any>error
    );

Lines 53 and 55 appear quite similar... why would one work while the other fails?

Even when attempting to execute just these two simple lines, the error persists:

var rrr: OffertRegion[];  //OK
this.offert.Regions = rrr; //OK

var ooo: OffertProduct[];  //OK
this.offert.Products = ooo; //ERROR !!!

Any insights on how to resolve this issue would be greatly appreciated. Thanks!

Answer №1

Success! I managed to fix the issue...

All it took was stopping the server and restarting ng serve...

And just like that, everything is back up and running smoothly!

I must've gotten a bit sloppy with all the copy/paste/rename actions... Farewell for now!
