Mongodb find a document with all subdocuments satisfying a condition

Question

I have Game collection in my DB:

var game = {
  players: [{username:"user1", status:"played"},
            {username:"user2", status:"accepted"}]
}

As far as I understand query like this: db.games.find({"players.status":"played"}) will give me all games where at least one player has status "played". How can I find games with ALL players having status "played"?

Answer 1

If you only have one other status than "played" use the query:

db.games.find({ "players.status": { $ne:"accepted" } })

You can adjust the query to handle more status values, as long as they are all known at the time of the query.
