models / branch.js

var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var branchSchema = new Schema({
  merchant_id: { type: [String], index: true },
  contact_name: String,
  branch: String,
  phone: String,
  email: String,
  address: String,
  status: String,
  created_date: { type: Date, default: Date.now },
  merchants: [{ type: Schema.Types.ObjectId, ref: 'merchant' }]

});
var branch = mongoose.model('branch', branchSchema);
exports = branch;

models / merchants.js

var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var merchantSchema = new Schema({
  merchant_name: String,
  merchant_type: String,
  contact_name: String,
  phone: String,
  email: String,
  Address: String,
  created_date: { type: Date, default: Date.now },
  branches: [{ type: Schema.Types.ObjectId, ref: 'branch' }]
});
var merchant = mongoose.model('merchant', merchantSchema);
exports = merchant;

index.js

var express = require('express');
var router = express.Router();
var bodyParser = require('body-parser');
var mongoose = require('mongoose');
var merchant = mongoose.model('merchant');
var branch = mongoose.model('branch');

router.post('/merchants/:merid/branch', function(req, res, next) {
  var branchs = new branch(req.body);
  branch.post = req.post;
  branchs.save(function(err, post) {
    if (err) {
      return next(err);
    }
    req.post.branch.push(merchant);
    req.post.save(function(err, post) {
      if (err) {
        return next(err);
      }
      res.json(branch);
    });
  });
});

我收到以下错误：

    在 index.js 中，您不在任何地方包含您的模型 . 除非你在某个地方包含模型文件以填充mongoose对象中的模型，否则mongoose无法知道这些模型的存在 .

    index.js

    var express = require('express');
var router = express.Router();
var bodyParser = require('body-parser');
var mongoose = require('mongoose');

var models = require('./models.js'); //This calls the js file models which then run their code, adding the models to mongoose.

//Now accessible.
var merchant = mongoose.model('merchant');
var branch = mongoose.model('branch');
...

    models.js

    var merchants = require('./models/merchant.js');
var branch = require('./models/branch.js');
