I am retrieving data from a service and passing it to a component using Angular and receiving '[object Object]'

Searching for assistance with the problem below regarding my model class. I've attempted various approaches using the .pipe.map() and importing {map} from rxjs/operators, but still encountering the error message [object Object]

export class AppProfilesDetailsDO {
  envName?: string;
  envDesc?: string;
  envIpAddress?: string;
  envProfileName?: string;
  envCrDeployed?: string;
  envUrl?: string;
  envAdminConsoleUrl?: string;
  envDbSchema?: string;
  envDbUserId?: string;
  envGisSchema?: string;
  envPortNo?: number;
}

My component class:

import { Component, OnInit } from '@angular/core';
import { ProfileserviceService } from './profileservice.service';
import { AppProfilesDetailsDO } from '../models/AppProfilesDetailsDO';

@Component({
selector: 'app-profiledetails',
templateUrl: './profiledetails.component.html',
styleUrls: ['./profiledetails.component.css']
})
export class ProfiledetailsComponent implements OnInit {

appProfileData: AppProfilesDetailsDO[];

constructor(private profileService: ProfileserviceService) { this.appProfileData = [] }

ngOnInit() {
   console.log("In profiledetails component");
   this.profileService.getProfileSetUpDetails().subscribe(
    appProfileData => {
       this.appProfileData = appProfileData;
    }
  );
  console.log("Compenent Profile Data: "+this.appProfileData); ==> **displaying as ==> [object Object] in my console**
 } 
}

My service component:

import { HttpClient } from "@angular/common/http";
import { Injectable } from "@angular/core";
import { Observable } from "rxjs";
import { AppProfilesDetailsDO } from "../models/AppProfilesDetailsDO";

@Injectable({
  providedIn: 'root'
})
export class ProfileserviceService {

 BASE_PATH:string = "http://localhost:8080/getProfileSetUpDetails";

 constructor(private httpClient: HttpClient) {}

 httpOptions = {
    headers: new Headers ({
        'Content-type': 'application/json'
    })
 }
 appProfileData?: AppProfilesDetailsDO[];

 getProfileSetUpDetails() : Observable<AppProfilesDetailsDO[]> {
    return this.httpClient.get<AppProfilesDetailsDO[]>(this.BASE_PATH);
  }
}

Uncertain where the issue lies. Any insights would be greatly appreciated.

Thank you.

Answer №1

The issue lies with this specific line of code:

console.log("Component Profile Data: "+this.appProfileData);
. Attempting to combine an object with a string is causing the problem.

To resolve this, simply update that line to read as follows:

console.log("Component Profile Data: ", this.appProfileData);

For further clarification, consider the following example:

var data = { a: "ali" };

console.log("Component Profile Data: " , data); console.log("Component Profile Data: " + data); 

Answer №2

To view the output, follow this format

   console.log("Component Profile Data:", this.appProfileData);

Otherwise, it will attempt to log the combined string value with the result object which cannot be achieved

Answer №3

It's important to remember that you can't concatenate a string and an array of objects like this:

console.log("Component Profile Data: "+this.appProfileData);

To avoid issues, simply use the array directly like this:

console.log(this.appProfileData);
