产品seeder.js

var Product = require('../models/product');

var mongoose = require('mongoose');

mongoose.connect('localhost:27017/shopping');

var products = [
    new Product({
      imagePath: 'images/black_tee_flagship_p_symbol_right_340x380.png',
      title: 'Black Tee White P',
      description: 'P on chest [white], symbols on sleeve',
      price: 28
    }),
    new Product({
      imagePath: 'images/white_tee_purple_eye_pocket_340x380.png',
      title: 'White Tee Purple Eye',
      description: 'Embroidered Purple Eye',
      price: 28
    }),
    new Product({
      imagePath: 'images/black_tee_gold_dual_p_center_340x380.png',
      title: 'Black Tee Gold 2Ps',
      description: 'Black Tee 2Ps on Chest [gold]',
      price: 28

    new Product({

      title: 'White Tee Purple P',
      description: 'P Logo + POPULAR underneath',

    }),
    new Product({

      title: 'Black Tee Blue 2Ps',

      price: 28
    }),
    new Product({

      title: 'White Tee POPULAR',
      description: 'POPULAR on chest [white on black]',
      price: 28
    })
];

var done = 0;

for (var i = 0; i < products.length; i++) {
    products[i].save(function(err, result) {
        done++;
        if (done === products.length) {
            exit();
        }
    });
}

function exit() {
    mongoose.disconnect();
}

Answer 1

您的连接字符串需要更新：它缺少URL架构。

您的连接字符串必须是：

mongoose.connect('mongodb://localhost/shopping');

由于27017是MongoDB的默认端口，因此您可以将其保留。
