How to remove an array element in mongodb

Question

productos: [
  {
    name: element 1
    number: 3167518236
    email: "[email protected]"
  }
  {
    name: element 2
    number: 3167518236
    email: "[email protected]"
  }
{
    name: element 3
    number: 3167518236
    email: "[email protected]"
  }
]

How can I for example remove the array two where name: element2 number: 3167518239 and email: [email protected]

I'm using this but it doesn't work!

db.list.update({},{"$unset":{productos:{name:"element 2"}}})

Removing an element from an array in mongodb is done using the $pull operator.

For your particular case, you can use {name:"element 2"} as the query inside the pull specification.

db.usuarios.update({},{"$pull":{productos:{nombre:"element 2"}}}) still not working!
