问题 I've been trying to get Firebase to work real time and i have a couple of issues. What i want to achieve is to be able to tell when a new document is added to a collection, just that, nothing more. What seems to be happening is my code always returns all the documents in the collection. Below is my code: listenNewPost(int categoryId, Users user, Function(DocumentSnapshot) onData) async { var ref = this._firestore.collection('posts').reference(); var query = ref.orderBy('created_at',

问题 When signing up a user, I get no error what so ever, the signup works, but it doesn't create a new DB collection with the signup email. Furthermore, redirecting the user to /account/dashboard.html doesn't work. Any ideas? I am very new to all of this, only 4 days in so if you could please explain things a little simpler to me that would be very much appreciated. // sign up the user firebase.auth().createUserWithEmailAndPassword(email, password).then(cred => { return db.collection('users').doc

问题 I'm working on a side project and want to let my users check if their friends have accounts. Currently I've implemented it like this: Read phone contacts for emails Loop through the emails Make .get() query on the user database 1 for users with that email If data comes back, the friend is on the platform and an invite button is displayed Free quota 2 exceeded within an hour The thing is that any .get is considered a read operation, even if no data comes back. Their doc.exists can only be tun

问题 Trying to write integrations tests for HTTPS function (implemented as an express app) that use Firestore as DB Since its an integration test, I don't want to mock the Firestore DB in this case, however, since they perform network calls, they take time to execute Is there a Firestore local emulator to use in this scenario? There is an option to config Firestore in offline mode, maybe that's the way? Didn't find any documentation in Firebase on this use case AskFirebase 回答1: You have to setup a

问题 As I know Firebase on Flutter will automatically read from cache first but I noticed while development that an app just play around with almost 1 stream that has 10 or 15 document I have reach reads above 4000 reads! By this way if 10 users has used my app I will pay all I have, so I have recheck every query, snapshot and put this code to know print(itemDoc.metadata.isFromCache ? "itemDoc NOT FROM NETWORK" : "itemDoc FROM NETWORK"); Edit write the code and more explain I noticed this issue

问题 I'm setting up my Firestore security rules, but run against one issue wherein I want to limit updating only one specific field within a document by using the hasOnly function. The problem is that I keep getting 'denied' results using the simulator. I'm surely doing something simple wrong... I'm trying to prevent that somebody could update other fields in the document than update_requested_time , but allow them to update this particular field. When using the example from the Firestore
