Lets say i have a group_members document like
> "_id" : ObjectId("59969a5b421aa92f5a6cf5fa"),
> "inserted_at" : "2017-08-18T07:42:19.332000Z",
> "referrers" : [
> {
> "referrer_id" : ObjectId("59705daa421aa94043b32721"),
> "alias_name" : "john"
> },
> {
> "referrer_id" : ObjectId("5970698f421aa9404373c493")
> "alias_name" : "mery"
> }
> ],
> "user" : {
> "name" : "abcd",
> "phone" : "9876543210",
> "user_id" : ObjectId("59706850421aa94043a570c3")
> }
Now i need to unset only that match %{referrers: %{referrer_id: ObjectId("5970698f421aa9404373c493")}} .
I tried db.group_members.update({ "_id": ObjectId("59969a5b421aa92f5a6cf5fa") }, {$unset: {"referrers": {"referrer_id": ObjectId("59705daa421aa94043b32721")}}}, false, true) but this is deleting complete referrers. But i want to delete referrer_id that matches only. How can i do this??
