问题 I'm very new in Angularfire. I created a Firebase parent node, with several other parents. Now I need to know how to rename the main parent node. 回答1: You cannot rename it easily within the console, but you can add a new node with the same content "Meeting with..." and delete the existing node. 回答2: Thanks Björn, Finally I found it. $scope.addMeeting = function(){ if($scope.meetingEditCheck){ var key = $scope.editKey; var newPostKey = firebase.database().ref().child('users/' + firebaseUser

问题 I'm trying to let user set the priority of an item with "ref.setPriority(priority);" but I also want to make sure they can't set it to less than "current_priority -10". But this expression: ".write": "data.getPriority() - newData.getPriority() > 10" is giving me an error "expression: left operand is not a number".

问题 If I create a new user with createUserWithEmailAndPassword , even though I didn't verify the mail yet, that user is already logged in. And his .emailVerified === false , and until here all good. Now, I go to the mail, verify it using the link, go back to the web app, it is still .emailVerified === false so I refresh the page, now .emailVerified === true . So I try to reach this doc: public async getPublicUserDetails() { const currentUserId = this._angularFireAuth.auth.currentUser.uid; try {

问题 According to the Angularfire docs, when working with an object returned through $asObject() , you can set priority for said object by defining a $priority property on the object and then using $save() . My code works great, but $priority isn't doing anything.

问题 Does the AngularFire service use REST under the hood? If so is there no limits in the hacker plan, because the Firebase page on pricing says: REST API requests don't count towards your connection limits ? 回答1: The AngularFire library uses Firebase's regular JavaScript/Web SDK under the hood. Each client keeps a connection open to Firebase servers, so will count towards the connection limits. You can easily verify this yourself by creating a minimal AngularFire client and opening it in a few

问题 Beginning to dive into AngularJS so I went to their website, but got stuck on the wire up a backend portion where Angular uses Firebase. The first issue came from the ordering of dependencies: angular.module('project', ['ngRoute', 'firebase']) changed to angular.module('project', ['firebase', 'ngRoute']) But now it's telling my that $add , in my $scope.save call, is undefined. Similar $add undefined questions are here and here, but neither seem to apply. Note: I'm running node's http-server ,
