mongodb createIndex vs ensureIndexes vs ensureIndex

[Alexander Mills]

 I have this code and it works:

var JobModel = null;

var get = function (cb) {

    if(JobModel === null){
        JobModel = mongoDB.model('jobs', jobSchema);

        //TODO: db.collection.createIndex(keys, options)

        JobModel.ensureIndexes(function(err){
            if(err){
                console.log(colors.bgRed(err));
            }
            cb(err,JobModel);
        });
    }
    else{
        cb(null,JobModel);
    }
};

but I can't find any reference to ensureIndexes in the MongoDB documentation.

what is the difference between ensureIndex and ensureIndexes and createIndex?

ensureIndex, now depreciated, is an alias for createIndex http://docs.mongodb.org/manual/reference/method/db.collection.ensureIndex/

As for ensureIndexes... never heard of it either, you're using some type of framework? Perhaps it's some type of wrapper?
