In the MongoDB console how can I remove a record by id? Here\'s my collection :

[

     \"_id\" : { \"$oid\" : \"4d512b45cc9374271b02ec4f\" },
     \"nam         


        

Answer 1

Do you have multiple mongodb nodes in a replica set?

I found (I am using via Robomongo gui mongo shell, I guess same applies in other cases) that the correct remove syntax, i.e.

db.test_users.remove({"_id": ObjectId("4d512b45cc9374271b02ec4f")})

...does not work unless you are connected to the primary node of the replica set.
