@PTL 修改system.version 的 authSchema版本為3, default 是 5
> use admin
switched to db admin
> var schema = db.system.version.findOne({"_id" : "authSchema"})
> schema.currentVersion= 3
3
> db.system.version.save(schema)
然後再創建用戶, 該用戶就會是用 MONGODB-CR認證方式, 所以登入驗證是看創建用戶時是用哪個版本的.
{
"_id" : "admin.peter",
"user" : "peter",
"db" : "admin",
"credentials" : {
"MONGODB-CR" : "4bbb5dc38596aed15e8eb8ead050f4ff"
}
目前採取的解決方式 :
db.coll1.find({ "receives.received" : {$exists : true} }).forEach( function(d) {
var at = d.receives;
at.forEach(function(att)
{
att.new_received = NumberInt(att.received);
delete att["received"];
});
db.coll1.update({_id:d._id},{$set:{receives:at}});
});
{
"sender" : "AA",
"receiver" : "BB",
"type" : "chat",
"time" : ISODate("2017-03-08T23:54:33.000+0000"),
"receives" : [
{
"time" : ISODate("2017-03-08T23:54:33.000+0000"),
"username" : "BB",
"received" : NumberInt(0)
}
]
}
