MongoDB：如何将此哈希添加到集合中的每个文档
[英]MongoDB: How to add this hash to every document in a collection
问题描述
I need to add a hash like this to every document in my users collection: 
我需要向users集合中的每个文档添加这样的哈希：
"authorization" : {
"_id" : ObjectId("52712baabe40ac667d000001"),
"all" : "true",
"boxscore" : "false",
"created_at" : ISODate("2013-10-30T15:54:18.397Z"),
"depth_charts" : "false",
"fantasy_news" : "false",
"injuries" : "false",
"matchups" : "false",
"news" : "false",
"odds" : "false",
"play_by_play" : "false",
"previews" : "false",
"recaps" : "false",
"schedule" : "false",
"standings" : "false",
"statistics" : "false",
"updated_at" : ISODate("2013-11-12T21:47:13.808Z")
}
Some users already have this hash, but not all of them. 一些users已经具有此哈希，但不是全部。 It's okay to overwrite existing users if they already have the document embedded. 如果现有用户已经嵌入文档，则可以覆盖它们。 Is there a way in MongoDB's console using some JavaScript in order to get this done? MongoDB的控制台中是否有某种方法可以使用一些JavaScript来完成此任务？
I should also note, that this is an embedded document. 我还应该注意，这是一个嵌入式文档。 So ObjectId should be unique for each document in the users collection. 因此，对于users集合中的每个文档， ObjectId应该是唯一的。

db.users.update({}, {$set: {authorization: {
"_id" : ObjectId(),
"all" : "true",
"boxscore" : "false",
"created_at" : ISODate("2013-10-30T15:54:18.397Z"),
"depth_charts" : "false",
"fantasy_news" : "false",
"injuries" : "false",
"matchups" : "false",
"news" : "false",
"odds" : "false",
"play_by_play" : "false",
"previews" : "false",
"recaps" : "false",
"schedule" : "false",
"standings" : "false",
"statistics" : "false",
"updated_at" : ISODate("2013-11-12T21:47:13.808Z")
}}}, {multi: true})
