Wie man ein Schema in Mongoose registriert und aufruft

Angenommen, die beiden obigen Codes befinden sich in zwei verschiedenen Dateien und im selben Ordner. Der Dateiname des Schemas lautet comment.js

var mongoose = require('mongoose'),
  path = require('path'),
  config = require(path.resolve('./config/config')),
  Schema = mongoose.Schema;

var Commentsscheme = new Schema({
  articleid: {
    type: Schema.ObjectId
  },
  fromuser: {
    type: String
  },
  touser: {
    type: String
  },
  comment: {
    type: String
  }
});

module.exports = mongoose.model('Comment', Commentsscheme);

und in anderen js-Dateien verwenden Sie dieses Schema wie folgt

var path = require('path'),
  mongoose = require('mongoose'),
  passport = require('passport'),
  // here you need to put the path/name of the file so that module will load.
  Comments = require('comment.js');


/* ------ Inserting a comment  ------ */
exports.insertcomment = function (req, res) {
  var comments = new Comments(req.body);
  console.log(comments)
  comments.status = 1;
  var data = {};
  comments.save(function (err,resl) {
    if (err) {
      console.log(err);
      return err;
    } 
     data = { status: false, error_code: 0, message: 'Unable to insert' };
    if (resl) {
      data = { status: true, error_code: 0,result: resl, message: 'Inserted successfully' };
    }
      res.json(data);
  });
};
