How to get doc Id from firestore?

manpreet Best Answer 2 years ago

I am trying to write code for an admin to update users field values stored in cloud FireStore, I'm unable to get doc Id and update the field values in cloud Firestore.

I'm building a cross-platform mobile App using the ionic framework in the front-end and firebase in the back-end, this app has a single admin. Admin will control users from accessing a few parts of the app, so, to do that, I will have to update field values in the user document in Firestore.

import { Component, OnInit } from '@angular/core';
import { User } from 'src/app/services/user/grade.service';
import { AdminService } from 'src/app/services/admin/admin.service';
import { Observable } from 'rxjs';
import { AngularFirestoreCollection, AngularFirestore } from 'angularfire2/firestore';
import {map} from 'rxjs/operators';
import * as firebase from 'firebase/app';
import 'firebase/auth';
import 'firebase/firestore';
export interface usrId extends User {
  id: string;

}
@Component({
  selector: 'app-student-details',
  templateUrl: './student-details.page.html',
  styleUrls: ['./student-details.page.scss'],
})
export class StudentDetailsPage implements OnInit {
public docId;
public userEmail;
public userName;
public data:any;
public user: User;
public userData:any;
public userStatus;
public visible: boolean;
public isDisabled: boolean; 
public isStatus: boolean;
public newStatus;
public users: Observable<User[]>;
private userProfileCollection: AngularFirestoreCollection<User>;
public uData: firebase.firestore.DocumentReference;
public currentUser: firebase.User;

    constructor(private adminService: AdminService, public db: AngularFirestore){
    this.userProfileCollection = this.db.collection<User>('userProfile');
    this.users = this.userProfileCollection.snapshotChanges().pipe(
      map(actions => {
        return actions.map(a => {
          const udata = a.payload.doc.data() as User;
          const
                                                

                                                                                                        
                                                    
                                                
                                                

                                                    

                                                        
                                                            0
                                                            views 

                                                            0
                                                                likes 
                                                            
                                                            

                                                            0
                                                            shares
