Mongoose update multiple documents

问题

Actually i am using mongoDB, and i am able to update document with single ObjectID, so right now i want to perform update on multiple documents having different ObjectID, i did considerable search, came to know {multi:true} will help to update multiple documents. Let's say i have

var uid = {'Userid': ObjectId(..)};
var id = {'Newid': Object(..)};

now i want to perform update on both of these different documents having different ObjectId' s total separatley, so far i tried this considering "xyz" and "abc" array's in Schema just for demo

var update_uid = {$push:{'xyz': some_id}};
var update_id = {$push:{'abc': some_other_id}};

Test.update(uid,id,update_uid,update_id,{multi:true},function(){..});

this is wrong i know, i mentioned it for the records just in case, Any help and suggestion would be much appreciated

回答1:

If you have multiple ids that you want to match you can use the keywork $in which checks if there's any matches in the array. Now that you also have multiple properties that you want to check you can user the $or keyword, which will find a match if either of the objects in the array matches a document in the database.

var userIds = [{'Userid':ObjectId(..)}, {'Userid':ObjectId(..)}];
var newIds = [{'Newid': Object(..)}, {'Newid': Object(..)}];

var query = {
  $or: [{$in: userIds}, {$in: newIds}]
}
