是否可以批量更新_id字段中包含_id :ObjectId("22332"
)的mongo集合为字符串,因此使用_id : "22332"
我正在使用Meteor,我已经使用mongoimport导入了csv,但它自动将ObjectId添加为(" 22332")我不想破坏默认的流星_id
功能并且必须放{每个javascript文件都有{1}}。
._str
我想要这个
{
"_id" : ObjectId("5696cf153f8d6d60f723268b"),
"NTitle" : 18,
"field1" : "company announces Private Placement",
"field2" : "111099432820040602PP.pdf",
"field3" : "Vancouver, BC, June 2, 2004...... ",
"field4" : "2004-02-06",
"field5" : "YES"
}
这是一个插入脚本。
{
"_id" : 5696cf153f8d6d60f723268b,
"NTitle" : 18,
"field1" : "company announces Private Placement",
"field2" : "111099432820040602PP.pdf",
"field3" : "Vancouver, BC, June 2, 2004...... ",
"field4" : "2004-02-06",
"field5" : "YES"
}
答案 0 :(得分:2)
这是解决我问题的一个粗略示例。
从phpmyadmin导出csv
在本地安装mongodb
运行
mongoimport -h localhost:3001 --db meteor --collection news4 --type csv --file env_news.csv --fields NID,NTitle,NPDF,NDesc,NAdded,NActive
服务器/ changeData.js 强>
var test = News4.find().fetch();
var test1 = News4Final.find().fetch();
for (i = 0; i < test.length; i++){
News4Final.insert({_id : test[i]._id._str}); //Run this Firsttime.
//Run everything below after first run
//var submitted = new Date(test[i].NAdded);
/*News4Final.update(test1[i]._id, {$set: {
title: test[i].NTitle,
PDF : test[i].NPDF,
postContent : test[i].NDesc,
submitted : submitted
}},{multi: false});*/
}
Dumb local Databse
mongodump --port 3001
senddatabase upto compose.io mongodb server。
mongorestore --host caneww.60.mon342.com:10654 --db enwave -u admin -p password dump/meteor
使用meteor up并在环境变量中设置数据库。同时在mup.json
中关闭mongodb setup为false"MONGO_URL": "mongodb://admin:password@cand4ate.40.mongolayer.com:10644,candidate.12.mongolayer.com:11274/enwdve?replicaSet=set-569886d8c55a7400102b",
"MONGO_OPLOG_URL": "mongodb://admin:password@candi4te.40.mongolayer.com:10254,candidate.12.mongolayer.com:1d274/local?authSource=enwddve"
