I’m trying to update a list of objects similar to this: 

var lista = [ { _id: 57ea29361b297553c99d702f,
    nome: 'Meu nome',
    __v: 0 },
  { _id: 57ea29371b297553c99d7031,
    nome: 'Meu outro nome',
    __v: 0 } ]

model.update({}, lista)
        .then(function (result) {
            console.log(result);
        }, function (error) {
            console.log(error);
        });

but give me that back:

{ Okay: 0, n: 0, nModified: 0 }

if you pass only one of the list it works

model.update({}, result[0])...

{ Okay: 1, nModified: 1, n: 1 }

node.js mongodb mongoose

  • I’m not sure but it won’t be necessary {multi: true} in the arguments ? https://docs.mongodb.com/manual/reference/method/db.collection.update/#multi-parameter

  • already tried model.update({}, list, { multi: true }), does not work.

  • I think it’s only good for equal changes for all documents

  • You want to update what? The model? If this list of your example is the new names for each document, you will need an update for each doc. Type: lista.forEach(function(item){ model.update({_id: item._id}, {nome: item.nome}).then(...); });

  • @sergiopereira works :), but it would be nice to have something from mongodb that already does this, can put as an answer.
