Recently, I created a Firebase cloud function where my goal is to access every user's internal collection named 'numbers' and examine each document within that collection for some comparisons.
Do you have any insights on how I can achieve this?
Despite being new to Firebase, I am struggling with the database navigation commands as they are not sticking very well with me.
I have experimented with various commands but haven't had much success
const snapshot = functions.database.collection('users').collection('numbers').get()
let sfRef = db.collection('users');
sfRef.getCollections().then(collections => {
collections.forEach(collection => {
console.log('Found subcollection with id:', collection.id);
});
});
Below is a general outline of the cloud code structure
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
export const prize1 = functions.pubsub.schedule('every 5 minutes').onRun((context) => {
const users = functions.database.ref('/users/numbers')
console.log("")
return null;
});
While I believe I understand the concept, I am encountering difficulties with the syntax.
The process involves accessing the collection of users, iterating through each user document, going into the 'numbers' collection within each user, examining each document within the 'numbers' collection for logic/comparisons based on the numbers field.
Hopefully, these explanations shed light on my database organization.
