Mongoose create multiple documents

Question

I know in the latest version of Mongoose you can pass multiple documents to the create method, or even better in my case an array of documents.

var array = [         


        

Answer 1

You can access the variable list of parameters to your callback via arguments. So you could do something like:

Candy.create(array, function (err) {
    if (err) // ...

    for (var i=1; i<arguments.length; ++i) {
        var candy = arguments[i];
        // do some stuff with candy
    }
});

Answer 2

by insert function of collection db, example:

Model.collection.insert(array, (err, list) => {
  if (err) throw err;

  console.log('list:', list);
});

Answer 3

With Mongoose v5.1.5, we can use insertMany() method with array passed.

const array = [
    {firstName: "Jelly", lastName: "Bean"},
    {firstName: "John", lastName: "Doe"}
];

Model.insertMany(array)
    .then(function (docs) {
        response.json(docs);
    })
    .catch(function (err) {
        response.status(500).send(err);
    });

Answer 4

According to this ticket on GitHub, Mongoose 3.9 and 4.0 will return an array if you supply an array and a spread of arguments if you supply a spread when using create().
