Currently, I am in the process of learning Angular by developing a web application for my parish. I have implemented a method for deleting items in the products-list.component.ts file which appears to be technically correct. However, when I attempt to run npm start, an error occurs with the following code:
TS2339: Property 'subscribe' does not exist on type 'Promise'.
I apologize if my description of the issue does not adhere to the formal guidelines, as I am relatively new to this field and might not be articulating the problem accurately. Thank you for your understanding.
The specific error is arising within the onDelete method.
In other classes where similar code is used, I have not encountered this particular error before. Could there be any missing imports in the list.component-products?
import { Component, OnInit, SystemJsNgModuleLoader } from '@angular/core';
import { NgForm } from '@angular/forms';
import { Prodotti } from 'src/app/model/prodotti.model';
import { Router, ActivatedRoute } from '@angular/router';
import { JsonPipe } from '@angular/common';
import { ProdottiListService} from 'src/app/features/prodotti/components/prodotti-list/prodotti-list.service';
import { ToastrService } from 'ngx-toastr';
let Header_Msg = "Gestione Prodotti";
@Component({
selector: 'app-prodotti-list',
templateUrl: './prodotti-list.component.html',
styleUrls: ['./prodotti-list.component.css']
})
export class ProdottiListComponent implements OnInit {
constructor(private service: ProdottiListService, private toastr: ToastrService) {
}
ngOnInit() {
this.service.refreshList();
}
populateForm(emp: Prodotti) {
this.service.formData = Object.assign({}, emp);
}
onDelete(id: number) {
if (confirm('Confermi la cancellazione del Record ?')) {
this.service.deleteProdotti(id).subscribe(res => {
this.service.refreshList();
this.toastr.warning('Cancellazione eseguita con successo', Header_Msg);
})
}
}
}
