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：

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：

1
D:\desk\JavaScript\MongoDemo>node app.js
---printBrief()---------------------------------------
iPhone SE ￥4999
Huawei Mate8 ￥4988
Mi Max ￥1650
Samsung S6 Edge ￥3850
Nokia 1000 ￥200

其中，各个.json的文件内容如下：

    "name"  : "Apple",
    "country" : "The United States"
  }
}

{

}

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。

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。

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();
})
