问题 I'm building a basic CRUD app with vue.js and firebase. I'm trying to build out a favorites functionality and have ran into a persistent problem storing the data. When a using clicks the add to favorites button I'm attempting to add the document id to an array in a "user profile" document. Here's the code: export function addNewUserAction (type, key, userID){ console.log(userID); console.log(key); firebase.firestore().collection('userActions').add({ type: type, listing: key, user: userID,

问题 I am developing an app that will offer the possibility to filter the users you search (gender, age, location, ...). I want to make this fast and as cheaper as possible, so I have decided to store my data as a n-ary tree, just something like this: ----- Users ----- Root Node: Gender (male or female) -male --country (nodes: USA, UK, Spain, Germany, France, Italy, ...) ---age (nodes: 18, 19, 20, 21, 22, ..., 60) ->user (leaf nodes) -female --country (nodes: USA, UK, Spain, Germany, France, Italy

问题 I see in the Writing conditions for Cloud Firestore Security Rules documentation that a (server side) custom function can be run against new writes. My question is: do I even need to worry about sanitizing textarea user input before writing/saving that to FireStore, or does Firestore automatically do this? If I need to sanitize user input, what would a javascript function look like to do that? What characters should I disallow or remove from the string? Thanks in advance. 回答1: Firestore does

问题 I have a field which indicates the number of transactions. I would like to increment it by 1 as soon as a transaction occurs. I could'nt find any method to directly execute this. One method is to get the user first and then update the field with the received value + 1 , but this is too lengthy and slow. Can anyone tell me any other feasible method? 回答1: Firestore now has a specific operator for this called FieldValue.increment() . By applying this operator to a field, the value of that field

问题 I'm trying to figure out the correct way to use firestore.onSnapshot with react-redux.

问题 I'm trying to paginate data (infinitely scroll my tableview) using firestore. I've integrated the code google gives for pagination as best I can, but I'm still having problems getting the data to load in correctly. The initial set of data loads into the tableview as wanted. Then, when the user hits the bottom of the screen, the next "x" amount of items are load in. But when the user hits the bottom of the screen the second time, the same "x" items are simply appended to the table view. The

问题 I want to use await inside streambuilder. However, if you use async inside, you get an error. On the code below !!!!!!!! That's the part I want to solve. Thank you very much if I can tell you how. class _MemoStreamState extends State<MemoStream> { final _fireStore = Firestore.instance; @override Widget build(BuildContext context) { return StreamBuilder<QuerySnapshot>( stream: _fireStore .collection(widget.logInUsrEmail) .orderBy('id', descending: false) .snapshots(), builder: (context,

问题 I'm trying to connect to google firestore and for some reason my process.env.FIREBASE_PROJECT_ID keeps spitting out the error: @firebase/firestore: Firestore (7.17.1): Connection GRPC stream error.
