You never set user
:
export class UsersReportingComponent implements OnInit {
user: User = new User();
//...
}
Make sure to initialise your class fields before ngOnInit
by setting it in the constructor or directly on the field, or use the ?.
save navigation operator inside your template: [(ngModel)]="user?.id"
Also as stated in the comments, don't make your user field private
, because otherwise the AOT compilation will fail

It looks like you are retrieving user
data using this._userService.getter();
in ngOnInit()
. You could use *ngIf
to test whether the user
has been loaded prior to rendering the form to avoid this error:
<form (ngSubmit)="processForm()" *ngIf="user">
// ...
</form>
Another option would be to simply initialize some default values like ''
for string
for the user
object until the getter()
has resolved:
user: User = {
id: 42,
name: '',
email: '',
// ... remaining properties
}
Also, are you sure you are using getter()
correctly? Assuming your call is something along the lines of:
getter()
return this.http.get<User>('/some/api/url')
}
You'd consume that like:
ngOnInit() {
this._userService.getter().subcribe(user => this.user = user);
}
Hopefully that helps!
getter(){ return this.user; }

ngOnInit() { this.user = this._userService.getter(); }

It looks like you are retrieving user
data using this._userService.getter();
in ngOnInit()
. You could use *ngIf
to test whether the user
has been loaded prior to rendering the form to avoid this error:
<form (ngSubmit)="processForm()" *ngIf="user">
// ...
</form>
Another option would be to simply initialize some default values like ''
for string
for the user
object until the getter()
has resolved:
user: User = {
id: 42,
name: '',
email: '',
// ... remaining properties
}
Also, are you sure you are using getter()
correctly? Assuming your call is something along the lines of:
getter()
return this.http.get<User>('/some/api/url')
}
You'd consume that like:
ngOnInit() {
this._userService.getter().subcribe(user => this.user = user);
}
Hopefully that helps!
getter(){ return this.user; }
