Question

我为我的文件创建了模式，并按照下面的方式调用它，但它表示模式没有注册注释的错误........这是由于路径吗？

我的架构，

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
  }
});

mongoose.model('comments', Commentsscheme);

我的js，

   var path = require('path'),
  mongoose = require('mongoose'),
  passport = require('passport'),
  Comments = mongoose.model('comments');

/* ------ 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);
  });
};

我为我的文件创建了架构，并按下面的方式调用它，但是它表示架构没有注册注释的错误........任何人都可以建议帮助，.......... ..............

假设上面两个代码在两个不同的文件中并且在同一个文件夹中。和架构文件名是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);

在其他js文件中，您将使用此模式，如下所示

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);
  });
};

像下面那样导出模型，然后在路径文件或调用文件

中输入

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

现在需要它并用于保存评论。
