Info

In MongoDB 2.6 we can use $position modifier to specifies the location in the array during update of an array in a document. But I would like to insert in an array in a subdocument. // Document schema: { subdoc: { array: ['0', '1', '2', '5', '6'] } } // The following update pushes the elements in the end of array.. db.collection.update( { _id: tsId }, {$push: { 'subdoc.array': { $each:['3', '4'], $position:2 } }}); // So, the result is { subdoc: { array: ['0', '1', '2', '5', '6', '3', '4'] }} // But I expect { subdoc: { array: ['0', '1', '2', '3', '4', '5', '6'] }}

Please close this issue.. scotthernandez commented on Mon, 14 Apr 2014 13:08:59 +0000: Are you sure you are using 2.6.0? Please run "db.version()" to verify that the server is 2.6.0. I cannot reproduce this with 2.6.0 locally: > db.version() 2.6.0 > db.a.save({ subdoc: { array: ['0', '1', '2', '5', '6'] } ,_id:1}) WriteResult({ "nMatched" : 0, "nUpserted" : 1, "nModified" : 0, "_id" : 1 }) > db.a.find() { "_id" : 1, "subdoc" : { "array" : [ "0", "1", "2", "5", "6" ] } } > db.a.update({}, {$push:{"subdoc.array": {$each:['3','4'], $position:2}}}) WriteResult({ "nMatched" : 1, "nUpserted" : 0, "nModified" : 1 }) > db.a.find() { "_id" : 1, "subdoc" : { "array" : [ "0", "1", "3", "4", "2", "5", "6" ] } }
