所以，我是新来的MEAN堆栈，并且我试图种下MongoDB。我正在使用Mongoose与数据库进行通信，并且有大量文档建议我应该能够使用填充的JSON文件进行种子处理。播种Node/MongoDB应用程序的最佳方法是什么？
我已经试过：
node-mongo-seed;非常直截了当，但一直抛出阵列末尾的错误。 （或许丢失BSON模块有故障？）
{ [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 {]
mongoose-seed;也很简单，基本上把JSON对象放入一个变量，然后导出到数据库。有前途的，但是...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，它很可能是JSON结构中的语法错误，但与玩弄没有取得任何真正的解决方案（也许我错过了吗？）。我的JSON的示例：
{
{
"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，我不完全知道如何在JSON中指定的子文档（假设我可以播种进程摆在首位正常工作）。
这里是我的模型：
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);
如何导航这些问题的任何有识之士将不胜感激。谢谢！
这肯定帮我完成我正在寻找，至少部分方面。我不确定如何修改该过程以包含子文档（很可能是'mongodump'），但这是向正确方向迈出的一大步。谢谢！ – Antwisted
当你说包括子文档时，你是什么意思？ – peteb
[这篇文章]（http://stackoverflow.com/questions/29354858/create-id-on-subdocuments-on-mongoimport-jsonarray）可能会有助于你有关'mongoimport'的subdocs – peteb
