Firestore: how to perform a query with inequality / not equals

Question

I want select from Firestore collection just articles written NOT by me.
Is it really so hard?

Every article has field "owner_uid".

Answer 1

1. Track all user id in a single document (or two)

2. filter unwanted id out

3. Use "where in"

var mylistofidwherenotme =  // code to fetch the single document where you tracked all user id, then filter yourself out


database.collection("articles").where("blogId", "in", mylistofidwherenotme)
