Hello, I'm trying to get some info from a parent reference in Firebase/Collection.
As you can see here. I have a parent collection named "Sasushi", which has all the users information. and I have two subcollections which are "Booking" and "Reviews".
all the three collections (the parent and the children) has a "uid" in common. My questions is, when I display information from the "booking collection", I want to display also the "display_name" and "photo_url" of that user from the parent collection (sasushi). How can I do that? please help me.
