Mongoose create multiple documents

Question

Mongoose create multiple documents

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 = [{ type: 'jelly bean' }, { type: 'snickers' }];
Candy.create(array, function (err, jellybean, snickers) {
    if (err) // ...
});

My problem is that the size of the array is dynamic so in the callback it would be helpful to have an array of the created objects.

var array = [{ type: 'jelly bean' }, { type: 'snickers' }, ..... {type: 'N candie'}];
Candy.create(array, function (err, candies) {
    if (err) // ...

    candies.forEach(function(candy) {
       // do some stuff with candies
    });
});

Not in the documentation, but is something like this possible?

node.js
mongoose

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
    }
});

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().
