第一次使用 firestore 时出现此错误。根据我的研究，这似乎是 Ivy 的问题。我没有很多修改 tsconfig.app.json 的经验，这是我被指出的方向，遵循其他答案。

我能够从原始项目中修改的唯一一件事是使用 Angular Fire 6 而不是 5，这是我最初按照教程所做的。

这是 package.json：

{
  "name": "language",
  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e"
  },

我正在使用firebase + angularjs应用程序,我正在使用简单的电子邮件和密码验证,它正常工作.

我只是想知道我是否可以在firebase email + password auth正在使用的用户表上添加额外的用户数据,就像我想添加有关用户的计费信息和其他详细信息而无需在firebase上创建额外的节点/表来存储这些额外的数据.

我有这个数据结构,其中todos被组织为遵循path/todos/uid /

{
  "metausers" : {
    "simplelogin:1" : {
      "displayName" : "John Doe",
      "provider" : "password",
      "provider_id" : "1"
    },
    "simplelogin:2" : {
      "displayName" : "GI Jane",
      "provider" : "password",
      "provider_id" : "2"
    }
  },
  "todos" : {
    "simplelogin:1" : {
      "-JUAfv4_-ZUlH7JqM4WZ" : {
        "completed" : false,
        "done" : false,
        "group" : false,
        "private" : false,
        "subject" : "First"
      },
      "-JUAfveXP_sqqX32jCJS" : {
        "completed" : false,
        "done" : false,
        "group" : false,
        "private" : true,
        "subject" : "Second"
      },
      "-JUAfwXnMo6P53Qz6Fd2" …

Terminal -

    "WARNING in Invalid constructor parameter decorator in D:/New folder/SilverLife/node_modules/@angular/fire/fesm2015/angular-fire.js:

        { type: Object, decorators: [{ type: Inject, args: [PLATFORM_ID,] }] }

在我的 Angular 9 项目中集成 Angular firebase 时，我遇到了这个问题。

我FirebaseSimpleLogin用来创建用户并处理身份验证.

当我尝试通过该$createUser()方法创建一个简单登录的新用户时,如果已经使用了电子邮件地址,firebase将不会创建用户.但是,$set()在创建它们之后,我还使用将创建的用户保存到我的firebase中,并将其user.uid用作密钥.当尝试写入数据库时​​,即使用户名不是唯一的,firebase也会保存记录,因为简单登录只需要电子邮件和密码.那么,当用户名不被用作用户对象的密钥时,如何验证用户名是否唯一？

我正在创建这样的新用户:

$scope.createUser = function() {
  $scope.auth.$createUser('trinker@gmail.com', 'password').then(function(user, err) {
    if (!err) {
      ref.child('users/' + user.uid).set({
        email: user.email,
        username: user.username
      });
      console.log("success!");
    }else{
      console.log(err.message);
    }
  });
}

我的用户对象如下所示:

{
  "users" : {
    "simplelogin:28" : {
      "email" : "trinker@gmail.com",
      "username" : "jtrinker"
    },
    "simplelogin:30" : {
      "email" : "test@gmail.com",
      "username" : "jtrinker"
    }
  }
}

}

我需要使用uid作为每个用户的密钥,但我仍然需要用户名是唯一的.

如果一个对象中的属性对于另一个对象内的属性不是唯一的,我怎么能阻止firebase保存记录？

我正在研究一个Angular App与Firebase实时数据库相关的问题.我目前正在使用AngularFire访问Firebase数据库.

在阅读Vanilla Firebase和AngularFire记录之后,在实现我的应用程序的某些部分之后,我看到Firebase数据库所需的所有内容都可以在Vanilla Firebase的帮助下实现,而无需任何帮助AngularFire.

此外,AngularFire与之相比,仅提供有限数量的资源Vanilla Firebase.那么,为什么我要使用它AngularFire,而不是Vanilla Firebase当它有许多资源可用时呢？我无法理解这种情况.

使用AngularFire结束有Vanilla Firebase什么好处？

当我运行 npm run start 时，出现以下有关 firebase 的错误。

技术：Angular 版本 9、Firebase、Firestore、Geofirestore Angular CLI。

错误：

在 Angular 10 更新后，我收到了有关 Firebase 和 CommonJS 或 AMD 依赖项的这些警告！

我有一个调用addCheckin()方法的页面,它位于控制器内部.在控制器中,我试图创建一个如下引用:

var ref = firebase.database().ref("users/" + $scope.whichuser + "/meetings/" +$scope.whichmeeting + "/checkins");

$scope.whichuser并且$scope.whichmeeting是$routeParams,我从其他途径传递.这是我的签到控制器 -

myApp.controller("CheckinsController",
    ['$scope','$rootScope','$firebaseArray','$routeParams','$firebaseObject',
    function($scope,$rootScope,$firebaseArray,$routeParams,$firebaseObject){

        $scope.whichuser = $routeParams.uid;
        $scope.whichmeeting = $routeParams.mid;

        var ref = firebase.database().ref("users/" + $scope.whichuser + "/meetings/" +$scope.whichmeeting + "/checkins");

        $scope.addCheckin = function(){
            var checkinInfo = $firebaseArray(ref);
            var data={
                firstname:$scope.firstname,
                lastname:$scope.lastname,
                email:$scope.email,
                date:firebase.database.ServerValue.TIMESTAMP
            }

            checkinInfo.$add(data);
        }

}]);/*controller*/

我在这里遇到两个错误 -

错误1:

Error: permission_denied at /users/Vp2P1MqKm7ckXqV2Uy3OzTnn6bB3/meetings: Client doesn't have permission to access the desired data.

错误2:

使用 angularfire 时出现此错误。检查了我的进口，他们似乎是正确的。我曾尝试重新安装 angularfire，但它仍然抛出此错误。angularfire 有问题吗？
