数据准备

为了对Phone进行存储以及后续的查询，需要提前准备一些手机型号的数据以供练习使用。
为此准备了如下5个手机型号的数据：

123456789101112131415161718192021222324252627

var Phone = mongoose.model('Phone', phoneSchema);var arrPhone = [];var raw;raw = require('./raw.iPhoneSE.json');var iPhoneSE = new Phone(raw);iPhoneSE.printBrief();arrPhone.push(iPhoneSE); raw = require('./raw.huawei.Mate8.json');var huaweiMate8 = new Phone(raw);huaweiMate8.printBrief();arrPhone.push(huaweiMate8); raw = require('./raw.mi.max.json');var miMax = new Phone(raw);miMax.printBrief();arrPhone.push(miMax); raw = require('./raw.samsung.S6Edge.json');var s6Edge = new Phone(raw);s6Edge.printBrief();arrPhone.push(s6Edge); raw = require('./raw.nokia1000.json');var nokia1000 = new Phone(raw);nokia1000.printBrief();arrPhone.push(nokia1000);

由此，控制台打印如下：

1234567

D:\desk\JavaScript\MongoDemo>node app.js---printBrief()---------------------------------------iPhone SE ￥4999Huawei Mate8 ￥4988Mi Max ￥1650Samsung S6 Edge ￥3850Nokia 1000 ￥200

其中，各个

.json

的文件内容如下：

单条数据存储

可以通过

Model.save()

很方便对单条数据进行存储。
在这里

save()

是个

instance method

。

1234567

iPhoneSE.save((err, phone)=>{ if (err) { console.log(err); } else { console.log('Phone[' + phone.device + '] saved.'); }});

多条数据批量存储

也可以通过

Model.insertMany()

一次性批量存储多个。
在这里

save()

是个

static method

。

12345678910

Phone.insertMany(arrPhone, (err, arrPhone)=>{ if (err) { console.log('insertMany() failed.'); } else { console.log('---insertMany()---------------------------------------'); console.log('All phone devices saved.insertMany() saved.'); } // 批量存储后，打印当前存储个数 Phone.printCount();})
