angularfire2

The part it doesn't like is the get() method in ngOnInit(). Is says, "[ts] Property 'get' does not exist on type 'AngularFirestoreDocument<{}>'." I looked here: https://firebase.google.com/docs/firestore/query-data/get-data and it shows to use get() method for a single doc, but it just doesn't like that method for me? import { Component, OnInit, Pipe } from '@angular/core'; import { FormBuilder, FormGroup, Validators } from '@angular/forms'; import { Router, ActivatedRoute } from '@angular/router'; import { AngularFirestore, AngularFirestoreCollection, AngularFirestoreDocument } from

I am using AngularFire2 in an Angular2 project to do a very basic task, login and then show the logged in users information on the page. The seemingly simple snag I've hit is that I need to know the users UID to request that data from Firebase (my permissions state can only access key inside "/users" with own UID - pretty standard). I discovered in order to get the UID I need to subscribe to the af.auth observable and then inside there request the user data using af.auth.uid - which I've done successfully. I've also noted that af.database.object creates another observable, which I can in

I read this question Many to Many relationship in Firebase , and here describes how to create or structure many to many relationship within firebase(nosql database), and it is pretty easy, companyContractors companyKey1 contractorKey1: true contractorKey3: true companyKey2 contractorKey2: true contractorCompanies contractorKey1 companyKey1: true, companyKey2: true contractorKey2 companyKey2: true contractorKey3 companyKey1: true but when i want to get all contractors specific company, can i do it using only one request? because in this case i get only list of id, and after there, using js loop

I searched in many forums, questions, in doc but can't find the correct solution. Problem What is the best way to increment a value using angularfire2 ? I saw we could use [transaction()][] but it's not for angularfire2 actually. Or with snapshot ? user.service.ts incrementLike(userToIncrementLike){ this.af.database.object('users/' + userToIncrementLike.uid).subscribe((userObject) => { var newUser = { likes: userObject.likes + 1 }; }); this.af.database.object('users/' + userToIncrementLike.uid).update(newUser); } I tried also in this way : incrementLike(userToIncrementLike){ let obs = this.af

I have parent with many children like this: Parent:{ "childe1":"data", "childe2":"data", "childe3":"data", "childe4":"data", "childe5":"data" } How can I update the children [ childe1 , childe2 , childe3 ] at same time, preventing any other user from updating them at same time? Frank van Puffelen To update multiple properties at the same time, you can run an update() call: ref.child("Parent").update({ childe1: "newdata", childe2: "newdata", childe3: "newdata" }); You can even specify paths as the keys, in case the properties are at different levels in the tree. Even though that doesn't seem to

I have an Ionic page which is querying FirebaseListObservable to make dynamic searching on ion-searchbar. It works well with Angularfire2@4.0.0-rc.0 and firebase@4.5.0. After upgrading new release AngularFire 5.0 I get an issue about FirabaseListObservable has no exported from new Api. import { Component } from '@angular/core'; import { IonicPage, NavParams, ViewController } from 'ionic-angular'; import {AngularFireDatabase, FirebaseListObservable} from 'angularfire2/database'; import { Observable} from 'rxjs'; import { Response } from '@angular/http'; @IonicPage() @Component({ selector: 'page

Argument of type '{ query: { limitTolast: number; orderByKey: boolean; }; }' is not assignable to parameter of type 'QueryFn'.Object literal may only specify known properties, and 'query' does not exist in type 'QueryFn'. package.json "angularfire2": "^5.0.0-rc.3", "firebase": "^4.5.1", chat.service.ts getMessages(): FirebaseListObservable<ChatMessage[]> { return this.db.list('messages', { query: { limitTolast : 25, orderByKey: true} }); } Orlandster It's not working, because AngularFire expects a function to be passed as a second argument. I think your example was the right way to go during
