[英]Firebase/Firestore - How do I create a new document for a new user
[英]How do I make it so when I create a user it gets added to a 'user' Firestore?
目前很難弄清楚如何添加這樣的功能,即在創建帳戶時,該帳戶會在名為“用戶”的集合下添加到 Firestore。 根據我從其他人那里看到的,他們添加了這樣的內容
.then then(userCredential => {
firestore.collection('users').doc(userCredential.user.uid).set({name})
}
這是我嘗試后的代碼。 我不確定我應該在我的代碼中添加的位置。 目前我在this.fireauth.auth.createUserWithEmailAndPassword(this.email, this.password)
下擁有它,我所做的嘗試是該程序可以正常工作,我可以注冊一個帳戶並在身份驗證中查看該帳戶firebase 身份驗證用戶選項卡,但在 Firestore 中未創建“用戶”集合。 我目前很難從這里開始 go 。 我真正需要的是存儲在 Firestore 中的用戶 ID/名稱。
import { Component, OnInit } from '@angular/core';
import { Platform, AlertController } from '@ionic/angular';
import { LoadingController, ToastController } from '@ionic/angular';
import { Router } from '@angular/router';
import { AngularFireAuth } from '@angular/fire/auth';
import { AngularFirestore } from '@angular/fire/firestore';
@Component({
selector: 'app-register',
templateUrl: './register.page.html',
styleUrls: ['./register.page.scss'],
})
export class RegisterPage {
email: string = '';
password: string = '';
error: string = '';
username: string = '';
image: number;
constructor(private fireauth: AngularFireAuth, private router: Router, private toastController: ToastController, private platform: Platform, public loadingController: LoadingController,
public alertController: AlertController, private firestore: AngularFirestore) {
}
async openLoader() {
const loading = await this.loadingController.create({
message: 'Please Wait ...',
duration: 2000
});
await loading.present();
}
async closeLoading() {
return await this.loadingController.dismiss();
}
signup() {
this.fireauth.auth.createUserWithEmailAndPassword(this.email, this.password)
.then(res => {
if (res.user) {
console.log(res.user);
this.updateProfile();
userCredential => this.firestore.collection('users').doc(userCredential.user.uid).set({
name
})
}
})
.catch(err => {
console.log(`login failed ${err}`);
this.error = err.message;
});
}
updateProfile() {
this.fireauth.auth.onAuthStateChanged((user) => {
if (user) {
console.log(user);
user.updateProfile({
displayName: this.username,
photoURL: `https://picsum.photos/id/${this.image}/200/200`
})
.then(() => {
this.router.navigateByUrl('/home');
})
}
})
}
async presentToast(message, show_button, position, duration) {
const toast = await this.toastController.create({
message: message,
showCloseButton: show_button,
position: position,
duration: duration
});
toast.present();
}
}
這是我為我的數據庫設置的當前規則。
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /users/{userId} {
allow read: if request.auth != null;
allow write: if request.auth.uid == userId;
}
}
}
看起來箭頭function有問題:
userCredential => this.firestore.collection('users').doc(userCredential.user.uid).set({name})
看來您只初始化 function 但從不調用它。 嘗試將此行更改為:
this.firestore.collection('users').doc(user.uid).set({name})
或致電匿名 function 如果您更喜歡您的解決方案,例如:
//... some logic
const initialize = user => this.firestore.collection('users').doc(user.uid).set({name})
initialize(user)
