Model.init()

Parameters

• [callback] «Function»

This function is responsible for building indexes, unless autoIndex is turned off.

Mongoose calls this function automatically when a model is created using mongoose.model() or connection.model(), so you don’t need to call it. This function is also idempotent, so you may call it to get back a promise that will resolve when your indexes are finished building as an alternative to MyModel.on('index')

Example:

const eventSchema = new Schema({ thing: { type: 'string', unique: true }})
// This calls `Event.init()` implicitly, so you don't need to call
// `Event.init()` on your own.
const Event = mongoose.model('Event', eventSchema);
Event.init().then(function(Event) {
  // You can also use `Event.on('index')` if you prefer event emitters
  // over promises.
  console.log('Indexes are done building!');
});
