Custom rootRef

[Samir-R]

Hello,

I want to make a backoffice for a marketplace to allow sellers to manage their products, orders, customers...
For exemple, sellers will login to www.mywebsite.com/admin (the backoffice that I develop with the react-admin library)
Each seller will have his firestore collections, for example :

• root-collection
  ---- seller1 (document, "seller1" is equivalent to the "seller 1" uid )
  ---------- products (collection)
  ---------- categories (collection)
  ---------- orders (collection)
  ---- seller2 (document)
  ---------- products (collection)
  ---------- categories (collection)
  ---------- orders (collection)
  ....

For example, when "seller 1" log in and go to www.mywebsite.com/admin/products, he will see the list of his products, I want react-admin-firebase to retrieve the documents(products) of "root-collection/seller1/products" collection, when he create product, I want this new product to be stored in "root-collection/seller1/products". If "seller 2" create new category, I want the category to be stored in "root-collection/seller2/categories" ...

I try this, in options of FirebaseDataProvider, but not working :

...
const options = {
  logging: true,
  rootRef: () => {
      const auth = getAuth();
      const user = auth.currentUser;    
      if (user) {
        // User is signed in
        return 'root-collection/' + user.uid;
      } else {
        // No user is signed in.
        return 'root-collection/foo';
      }
  },
  app: firebaseApp,
...

it return always 'root-collection/foo' even if I signed in.

Do you have a solution for my use case ?

Thank you.
Sorry for my english.
