所以我有这个文件,我试图更新评论,当我这样做时,似乎用新信息覆盖了数组。任何想法为什么?
Confession.findOne({_id: confessionID}, function (err, confession) {
if (err){
console.log(err);
} else {
confession.update(
{$pushAll: {'comments.commentData':
[{comment: req.body.text, commenter: req.body.name }]
}},
{upsert: true},
function (err, confession) {
if (err) {
console.log(err);
} else {
res.send(confession.comments);
console.log(confession);
}
});
}
以下是所要求的示例文档
{ "__v" : 0,
"_id" : ObjectId( "5171c2bd47a7510000000002" ),
"absolves" : { "IDs" : [ null ],
"num" : 2 },
"comments" : { "commentData" : [
{ "comment" : "asdfas wdfwe cqwe qwe w w",
"_id" : ObjectId( "5179c9fa79c165e74d000002" ),
"timeStamp" : Date( 1366936058266 ) }],
"num" : 0 },
"condemns" : { "IDs" : [ null ],
"num" : 2 },
"facebook" : 1232876940,
"removed" : false,
"text" : " another confession",
"time" : Date( 1366409917817 ) }
答案 0 :(得分:0)
试试这个
{$push: {'comments.commentData':
{comment: req.body.text, commenter: req.body.name }
}},
