Question

Utilizing the .add() method in Firebase Cloud Firestore for working with nested

In the documentation for Firebase, it mentions updating nested objects. You can find out more about this here: https://firebase.google.com/docs/firestore/manage-data/add-data#update_fields_in_nested_objects

Here is my data structure:

let ref = db.collections('projects').doc('blabla')
ref.set({
    objOfObjects: {}
})

I am looking to add an object (value) with a randomly generated key to the objOfObjects field, similar to how the regular add function works. The key cannot be tied to any of the values in the object. Is there a way to achieve this within objOfObjects or should I consider restructuring my data?

Answer №1

If you want to add a field with a randomly generated name to a document in Firebase Firestore, you won't find a built-in function for that specific task. However, there is a workaround. You can create the random name yourself and then include it in the document. One approach is to utilize collection.add() to obtain the random name. According to a tip from Doug on Stack Overflow, this method does not immediately generate a new document.

var newId = store.collection('projects').doc().id;

let ref = db.collections('projects').doc('blabla');
var updates = {};
updates[id] = { ... }
ref.update(updates)

The process involves obtaining a unique id and storing it as mentioned earlier. Then, use the [] notation to assign the value of the id as the property name within the document. Finally, make use of the update() method to modify the existing document rather than overwriting it entirely.
