问题 How to update data of isVerified (Boolean) field. Personal Info is Map contains address and then isVerified. 回答1: To update isVerified , you have to do the following: Firestore.instance.collection("collection Name").document("documentId").updateData({ "Personal Info.address.isVerified": true, }).then((_) { print("success!"); }); 回答2: Since you did not provide your collection or document name I would just form one So lets assume every time we click a button the value should be changed to true

问题 Cannot get Firebase Cloud Functions for Firestore to trigger on onWrite of my collection. Trying to setup device to device push notification for chat app. Function is deployed and on Pay as you go plan, however, changes in document, updates or create in "chats" collection is not triggering. Firebase cloud messaging is supposed to send a push and write to the log. Neither is happening. Push is working with other sources. Thanks for your help, wish device to device push notifications was easier

问题 I have a document with the following structure: { "email" : "a@gmail.com", "value" : 100, "children" : [ { "email" : "b@gmail.com", "value" : 100 }, { "email" : "b@gmail.com", "value" : 200 } ] } I want to remove all elements with the email b@gmail.com from the children array.

Is there anyway to achieve this

问题 I'm working on a React project with Cloud Firestore. I have successfully fetched data from Firestore. But I could not set state these data to state. How can I set state these data. class App extends Component { constructor(props) { super(props); this.state = { items: [] }; } async componentDidMount() { const items = []; firebase .firestore() .collection("items") .get() .then(function(querySnapshot) { querySnapshot.forEach(function(doc) { items.push(doc.data()); }); }); this.setState({ items:

问题 I am writing a small program in react that manages a league of sorts. The problem I have is how do I allow access (read, write) to the matchdays of a league for the correct user. The matchdays are named "matchday-1", "matchday-2", and so on, and are collections of documents (the matches), and are subcollections inside the league. My firebase structure looks like this basically: leagues(collection) -> league(document) -> matchday-n(collection) -> match-m(document) where n and m are numbers.

问题 I want to read a document, get a field from that document, and set a variable to that field's value I expected my variable declared outside the Firebase getDocument function to be written to. The actual results are that the variable is being written to within the Firebase getDocument function but outside the function it is empty. Here's what I have tried: [1]: Modifying variable within firebase function - this didn't work for me because I can't translate it well with my current Swift skills

问题 I am trying to store a CSV file in a text field inside Cloud Firestore. However Firestore is stripping out all line breaks and storing the entire CSV file as a single line. The Firestore Data Types documentation does not say anything about a restriction on the type of characters that can be stored other than they should be UTF-8: Up to 1,048,487 bytes (1 MiB - 89 bytes). Only the first 1,500 bytes of the UTF-8 representation are considered by queries. Is there a documented restriction? If
