如何使用猫鼬创建收藏集

Question

我正在尝试使用Mongoose创建数据库，但是我不知道如何运行它/将其从代码推送到rot 3t。我使用的是上一课中的代码，当我删除具有相同名称的数据库时，无法再创建它。

var mongoose = require("mongoose");

// Save a reference to the Schema constructor
var Schema = mongoose.Schema;

// Using the Schema constructor, create a new UserSchema object
// This is similar to a Sequelize model
var ArticleSchema = new Schema({
  // `title` is required and of type String
  title: {
    type: String,
    required: true
  },
  // `link` is required and of type String
  link: {
    type: String,
    required: true
  },
  // `note` is an object that stores a Note id
  // The ref property links the ObjectId to the Note model
  // This allows us to populate the Article with an associated Note
  note: {
    type: Schema.Types.ObjectId,
    ref: "Note"
  }
});

// This creates our model from the above schema, using mongoose's model method
var Article = mongoose.model("Article", ArticleSchema);

// Export the Article model
module.exports = Article;

我想解释如何使用此代码创建新集合
