angularfire

I'm having trouble decorate the objects in my list returned by $asArray in angularfire with a new method (not decorating the array itself). The angularfire documentation seems to suggest that the right way to do this is to override the $$added method in the factory for $FirebaseArray, returning a new object that either encapsulates or extends the snapshot that gets passed in to that method. From the documentation : // an object to return in our JokeFactory app.factory("Joke", function($firebaseUtils) { function Joke(snapshot) { this.$id = snapshot.name(); this.update(snapshot); } Joke

This is the code I have right now: var url = 'https://*****.firebaseio.com/photos'; var promise = angularFire(url, $scope, 'photos', {}); promise.then(function() { //limit here. }); What code can I insert to limit what is returned from the firebase to only those have a specified priority (let's say the priority is "new)? Thanks for the help. Just pass in an already limited query to angularFire, like so: var ref = new Firebase("https://*****.firebaseio.com/photos"); var promise = angularFire(ref.startAt("new"), $scope, "photos", {}); 来源： https://stackoverflow.com/questions/17179532/using-limits

I tried an example app to connect to Firebase In my Main.ts I wrote this: import { bootstrap } from '@angular/platform-browser-dynamic'; import { enableProdMode } from '@angular/core'; import { AppComponent, environment } from './app/'; import { FIREBASE_PROVIDERS, defaultFirebase, firebaseAuthConfig, AuthProviders, AuthMethods } from 'angularfire2'; if (environment.production) { enableProdMode(); } bootstrap(AppComponent,[ FIREBASE_PROVIDERS, defaultFirebase({ apiKey: "MYKEY", authDomain: "MYDOMAIN.firebaseapp.com", databaseURL: "https://MYDOMAN.firebaseio.com", storageBucket: "MYDOMAIN

I have trouble fetching one unique item from my firebase using angularfire 1.0.0. To clarify, I want my app to fetch a post given a unique firebase id e.g. "-JkZwz-tyYoRLoRqlI_I". It works when navigating in the app e.g. clicking on a link to a specific post, but not on a refresh. My guess is that it has something to do with synchronization. Right now it works when fetching all posts and use it in a ng-repeat. This is a clue to why it works for one item when navigating to the page. This should probably not be hard since this should be a pretty standard operation, but i can't get it to work. I

So I have this for example in firebase clients { //clients with unique keys { invoices: { // Invoices with unique Keys } } } I'm returning all this with one ref like so: .controller('singleClientController', function($scope, $firebaseObject, fbUrl, $routeParams) { var id = $routeParams.id; var singleRef = new Firebase(fbUrl+'/clients/'+id); var client = this; client.details = $firebaseObject(singleRef); }) so in my html, I'm trying to return the $id for both the client and the invoice. I am able to get the client no problem with {{client.details.$id}} but when I try to do the same thing with

I am using Ionic 2 and Firebase to build a chat app. I add the following which is supposed to be used to add a filter: import 'rxjs/add/operator/filter'; ... public af: AngularFire ... this.firelist = this.af.database.list('/chat/', { query: { orderByChild: 'negativtimestamp' } }).filter(item => item.memberIds === 'xxx'); However, I get the following: [ts] Property 'filter' does not exist on type 'FirebaseListObservable'. ps. this.af.database.list(...) returns a FirebaseListObservable<any[]> . filter can be done on Observable but not on FirebaseListObservable . Question So how do I implement
