I'm running into an issue while attempting to retrieve a specific user from Firebase's Firestore.
export class TaskService {
tasksCollection: AngularFirestoreCollection<Task>;
taskDoc: AngularFirestoreDocument<Task>;
tasks: Observable<Task[]>;
task: Observable<Task>;
constructor(private afs: AngularFirestore) {
this.tasksCollection = this.afs.collection('tasks', ref => ref.orderBy('title', 'asc'));
}
getTask(id: string): Observable<Task> {
this.taskDoc = this.afs.doc<Task>(`clients/${id}`);
this.task = this.taskDoc.snapshotChanges().pipe(map(action => {
if (action.payload.exists === false) {
return null;
} else {
const data = action.payload.data() as Task;
data.id = action.payload.id;
return data;
}
}));
return this.task;
}
}
Here's my Component.ts file:
export class TaskDetailsComponent implements OnInit {
id: string;
task: Task;
hasHours = false;
showHoursOnUpdate: false;
constructor(
private taskService: TaskService,
private router: Router,
private route: ActivatedRoute
) { }
ngOnInit() {
// Get ID from the URL
this.id = this.route.snapshot.params.id;
// Retrieve client
this.taskService.getTask(this.id).subscribe(task => {
if (task != null) {
if (task.hours > 0) {
this.hasHours = true;
}
}
this.task = task;
});
console.log(this.id);
console.log(this.task);
}
}
The ID result is accurate, but the object (task) result comes up as undefined.
P.S. I also have functions for retrieving all users and adding a new user. Let me know in the comments if that information is relevant.
