I have been attempting to incorporate images (retrieved through an API) as the background-image of an element. However, I keep encountering the error message
Cannot read property 'url' of undefined <div class="col s12 m4" *ngFor="let partner of partners">
<div class="card" *ngIf='partner'>
<div class="card-image " [ngStyle]="{'background-image': 'url(' + partner?.photo['url'] + ')'}">
<a class=" btn-floating halfway-fab waves-effect waves-light blue left ">
<i class="material-icons ">shopping_cart</i>
</a>
<a class="btn-floating halfway-fab red " [routerLink]='"/dashboard/partners/edit/"+partner["id"]'>
<i class="large material-icons ">mode_edit</i>
</a>
</div>
<div class="card-content ">
<h5 class="center font-weight-400 ">{{partner.name}}</h5>
<p class="center ">{{partner.category.name}}</p>
</div>
</div>
</div>
and the corresponding controller:
export class PartnersListComponent implements OnInit {
partners: {}[] = [];
constructor(private _partnersService: PartnersService) {}
ngOnInit() {
this._partnersService.getPartners().subscribe(data => {
if (data.status == "200") {
this.partners = data.data;
}
});
}
}
Here is an example of the data:
category:'',
created_at:"2017-12-27 12:57:50",
deleted_at:null,
first_entry:1,
id:1,
name:"Zara",
photo:{id: 5, url: "example.jpeg"},
updated_at:"2017-12-27 12:57:50",
username:"zara-001"
