如何在mongoDb中初始化mongoose模式？

Question

I would like to to create database and collections for all schema/model files on node.js application startup/mongoose connection to db. (not to seed the database but initialise/set the structure schema on db)

My model:

var mongoose = require("mongoose");
var Schema = mongoose.Schema;

// define the schema
var modelSchema = new Schema({
    appId: {
        type: String,
        indexed: true
    }
});

// export the Model
module.exports = mongoose.model('Model', modelSchema)

And i am using this method to connect to DB:

mongoose.connect(mongodbUri, mongooseOptions);

At the moment mongoose creates the schema in db only when I insert something to the database.

如果您修复indexed是index架构中的，这最终将建立你的收藏，这样当你创建模型的指数也可以被创建。
