问题 I want to query a Firebase collection reference with a list of multiple document IDs within a Streambuilder, but it appears the only .where() query functions available are: Query where(String field, {dynamic isEqualTo, dynamic isLessThan, dynamic isLessThanOrEqualTo, dynamic isGreaterThan, dynamic isGreaterThanOrEqualTo, dynamic arrayContains, bool isNull}) I have tested isEqualTo and this works fine if I set a string to pass in, but I can't get this to work with a list. It appears there is

问题 I can't figure out how to fetch data from firestore when i have in data model reference (id) to another object, for example like this City {name: string; countryId: string; //primary key to another object in database } Country { name: string; } I m using AngularFire 5. After i fetch city i want fetch country and i want to asign country.name to city.countryId and i want return joined object city.

问题 All of the text in an application I'm working on is stored inside FireStore documents, so to retrieve it I use this bit of code db.collection("language").document("kCreateNewAccount").get() .addOnSuccessListener(new OnSuccessListener<DocumentSnapshot>() { @Override public void onSuccess(DocumentSnapshot documentSnapshot) { String viewText = lan.equals("en") ? documentSnapshot.getString("en") : documentSnapshot.getString("es"); createAccount.setText(viewText); } }); I've tried to put it into a

问题 I know how to READ and WRITE a document in Firestore, But how does one update() a Value of and object in an array of Maps without removing/deleteing? Just changing one value if needed. I have a Form that includes a FormArray, that are able to edit as an when there is an update on the price list. product = { id: "product id", brand: "Brand Name", model: "This is the model of the brand" lists: [ { location: "Location 1", price: "0.00" }, { location: "Location 2", price: "0.00" } ] } Component

问题 I have a users collection where each document contains a name field and and an access map. "users" :[ { "mHbVq5TUY7brlleejClKm71NBGI2": { "name": "Bob Johnson", "access": { "X0w1VaVIljR1Nc5u3Sbo" : true } } ] I would like the Firestore rules to allow creation of a new document only if it doesn't already exist and only if the person performing the action has had their email verified.

问题 I can request a specific document in a collection successfully. But I need to be able to query all documents, as Firestore (unlike the realtime database) doesn't support exporting. I know the following is not possible, but surely there is some way to export a whole collection? router.get('/firebase', function (req, res) { var admin = require('firebase-admin'); const firebaseConfig = require('../firebaseConfig.json'); admin.initializeApp({ credential: admin.credential.cert(firebaseConfig),

问题 Our database structure looks like that: trips 12345 toArea radius: 150 name: "citycenter" 54321 toArea radius: 250 name: "main street" We tried to create some rules for read from document: match /chats/{trip} { match /messages/{message} { allow read, write: if get(/databases/$(database)/documents/trips/$(trip)).data.toArea != null } } It's works fine but next rules doesn't works: allow read, write: if get(/databases/$(database)/documents/trips/$(trip)).data.toArea != null allow read, write:
