如何更新mongodb中字段的值？

Question

I have a document as follows in mongodb:

{
 "_id":"563f480fb5c2187503eefc1a",
 "ownerBy":"56335521f2f4a3150349d78d",
 "data":   {
   "username1":"76561198060520554",
   "username2":"76561198060520554",
   "username3":"76561198060520554",
   "username4":"76561198060520554",
   "username5":"76561198060520554"
  }, 
 "__v":0
}

The client wants to update the value of username1 to the following newValue :

{ newValue: 'as76561198060520554',
  id: 'username1',
  column: 'selectable' 
}

How can I find the field _id and replace that with newValue ?

Answer 1

Given the little information we have, this could possibly be what you're looking for!

Collection would be the name of your collection!

Collection.update({
"_id":"563f480fb5c2187503eefc1a"
},
{$rename: {"_id" : "newValue"}},
{$set: { 
newValue: 'as76561198060520554',

id: 'username1',
column: 'selectable' 
}},
{"upsert": true});
