播种Node/MongoDB应用程序的最佳方法是什么？

Question

所以,我是MEAN堆栈的新手,而且我试图播种MongoDB.我正在使用Mongoose与数据库进行通信,并且有大量文档表明我应该能够使用填充的JSON文件进行播种.

我尝试过的:

node-mongo-seed ; 非常简单,但在数组末尾始终抛出错误.(也许缺少的bson模块有问题？)

{ [Error: Cannot find module '../build/Release/bson'] code: 'MODULE_NOT_FOUND' }
js-bson: Failed to load c++ bson extension, using pure JS version
Seeding files from directory /Users/Antwisted/code/wdi/MEAN/seeds
----------------------
Seeding collection locations
err =  [SyntaxError: /Users/Antwisted/code/wdi/MEAN/seeds/locations.json: Unexpected token {]

猫鼬种子 ; 同样非常简单,基本上在导出到数据库之前将JSON对象放入变量中.有希望,但......更多错误......

Successfully initialized mongoose-seed
[ 'app/models/locationsModel.js' ]
Locations collection cleared
Error creating document [0] of Location model
Error: Location validation failed
Error creating document [1] of Location model
Error: Location validation failed
Error creating document [2] of Location model
Error: Location validation failed...

所以,我的想法是它可能是JSON结构中的语法错误,但是玩弄它并没有产生任何真正的解决方案(或者我可能错过了它？).我的JSON示例:

{
    {
        "header": "Dan's Place",
        "rating": 3,
        "address": "125 High Street, New York, 10001",
        "cord1": -73.0812,
        "cord2": 40.8732,
        "attributes": ["Hot drinks", "Food", "Premium wifi"],
        "hours": [
            {
                "days": "Monday - Friday",
                "hours": "7:00am - 7:00pm",
                "closed": false
            },
            {
                "days": "Saturday",
                "hours": "8:00am - 5:00pm",
                "closed": false
            },
            {
                "days": "Sunday",
                "closed": true
            }
        ],
        "reviews": [
            {
                "rating": 4,
                "id": ObjectId(),
                "author": "Philly B.",
                "timestamp": "new Date('Feb 3, 2016')",
                "body": "It was fine, but coffee was a bit dull. Nice atmosphere."
            },
            {
                "rating": 3,
                "id": ObjectId(),
                "author": "Tom B.",
                "timestamp": "new Date('Feb 23, 2016')",
                "body": "I asked for her number. She said no."
            }
        ]
    },
    {
        "header": "Jared's Jive",
        "rating": 5,
        "address": "747 Fly Court, New York, 10001",
        "cord1": -73.0812,
        "cord2": 40.8732,
        "attributes": ["Live Music", "Rooftop Bar", "2 Floors"],
        "hours": [
            {
                "days": "Monday - Friday",
                "hours": "7:00am - 7:00pm",
                "closed": false
            },
            {
                "days": "Saturday",
                "hours": "8:00am - 5:00pm",
                "closed": false
            },
            {
                "days": "Sunday",
                "closed": true
            }
        ],
        "reviews": [
            {
                "rating": 5,
                "id": ObjectId(),
                "author": "Jacob G.",
                "timestamp": "new Date('Feb 3, 2016')",
                "body": "Whoa! The music here is wicked good. Definitely going again."
            },
            {
                "rating": 4,
                "id": ObjectId(),
                "author": "Tom B.",
                "timestamp": "new Date('Feb 23, 2016')",
                "body": "I asked to play her a tune. She said no."
            }
        ]
    }
}

另外,我不完全确定如何在JSON中指定子文档(假设我可以让播种过程首先正常工作).

这是我的模特:

var mongoose = require('mongoose');

var subHoursSchema = new mongoose.Schema({
    days: {type: String, required: true},
    opening: String,
    closing: String,
    closed: {type: Boolean, required: true}
});

var subReviewsSchema = new mongoose.Schema({
    rating: {type: Number, required: true, min: 0, max: 5},
    author: String,
    timestamp: {type: Date, "default": Date.now},
    body: String
}); 

var locationSchema = new mongoose.Schema({
    name: {type: String, required: true},
    address: String,
    rating: {type: Number, "default": 0, min: 0, max: 5}, 
    attributes: [String],
    coordinates: {type: [Number], index: '2dsphere'},
    openHours: [subHoursSchema],
    reviews: [subReviewsSchema]
});

mongoose.model('Location', locationSchema);

任何有关如何处理这些问题的见解将不胜感激.谢谢!

您可以使用CLI在CLI中填充MongoDB mongoimport

它会将JSON文件加载到指定的MongoDB实例和集合中,您只需要mongod在执行之前运行实例.

这是一个使用的演练mongoimport.
