如何在MongoDB中正确执行批量upsert / update

I'm trying to:

我试图:

• Find a document according to a search criteria,

根据搜索条件查找文档,

• If found, update some attributes

如果找到,请更新一些属性

• If not insert a document with some attributes.

如果没有插入带有某些属性的文档。

I'm using a Bulk.unOrderedOperation as I'm also performing a single insert. And I want to do everything in one operation againast DB.

我正在使用Bulk.unOrderedOperation,因为我还在执行单个插入。而且我想在一次操作中再做一切DB。

However something it's causing nothing is being inserted for the update/upsert operation.

然而,正在为更新/ upsert操作插入一些不会导致任何问题。

This is the insert document:

这是插入文档:

  var lineUpPointsRoundRecord = {
    lineupId: lineup.id,  // String
    totalPoints: roundPoints, // Number
    teamId: lineup.team, // String
    teamName: home.team.name, // String
    userId: home.iduser, // String
    userName: home.user.name, // String
    round: lineup.matchDate.round, // Number
    date: new Date()
  }

This is the upsert document:

这是upsert文件:

  var lineUpPointsGeneralRecord = {
    teamId: lineup.team, // String
    teamName: home.team.name, // String
    userId: home.iduser, // String 
    userName: home.user.name, // String
    round: 0,
    signupPoints: home.signupPoints, // String
    lfPoints: roundPoints+home.signupPoints, // Number 
    roundPoints: [roundPoints] // Number
  };

This is how I'm trying to upsert/update:

这就是我尝试upsert / update的方式:

var batch = collection.initializeUnorderedBulkOp();

batch.insert(lineUpPointsRoundRecord);

batch.find({team: lineUpPointsRoundRecord.teamId, round: 0}).
  upsert().
  update({
    $setOnInsert: lineUpPointsGeneralRecord,
    $inc: {lfPoints: roundPoints},
    $push: {roundPoints: roundPoints}
  });

batch.execute(function (err, result) {
  return cb(err,result);
});

Why wouldn't it be upserting/updating?

为什么不进行上传/更新?

Note

That is JS code using waterline ORM which also uses mongodb native driver.

这是使用水线ORM的JS代码,它也使用mongodb本机驱动程序。

Your syntax here is basically correct, but your general execution was wrong and you should have "seperated" the "upsert" action from the other modifications. These will otherwise "*" and produce an error when an "upsert" occurs:

这里的语法基本上是正确的,但是你的一般执行是错误的,你应该从其他修改中“分离”“upsert”动作。否则,当发生“upsert”时,这些将“冲突”并产生错误:

LineupPointsRecord.native(function (err,collection) {

    var bulk = collection.initializeOrderedBulkOp();

    // Match and update only. Do not attempt upsert
    bulk.find({
        "teamId": lineUpPointsGeneralRecord.teamId,
        "round": 0
    }).updateOne({
        "$inc": { "lfPoints": roundPoints },
        "$push": { "roundPoints": roundPoints }
    });

    // Attempt upsert with $setOnInsert only
    bulk.find({
        "teamId": lineUpPointsGeneralRecord.teamId,
        "round": 0
    }).upsert().updateOne({
        "$setOnInsert": lineUpPointsGeneralRecord
    });

    bulk.execute(function (err,updateResult) {
        sails.log.debug(err,updateResult);
    });
});

Make sure your sails-mongo is a latest version supporting the Bulk operations properly be the inclusion of a recent node native driver. The most recent supports the v2 driver, which is fine for this.

确保您的sails-mongo是支持批量操作的最新版本,包括最近的节点本机驱动程序。最近支持v2驱动程序,这对此很好。

Typically I have always set upsert as a property on update. Also update should be able to find the record itself so no need to find it individually.

通常我总是将upsert设置为更新时的属性。此外,更新应该能够找到记录本身,因此无需单独查找。

Depending on the environment the $ may or may not be necessary.

根据环境,$可能需要也可能不需要。

batch.update(
 {team: lineUpPointsRoundRecord.teamId, round: 0},
    {      
      $setOnInsert: lineUpPointsGeneralRecord,
      $inc: {lfPoints: roundPoints},
      $push: {roundPoints: roundPoints},
      $upsert: true
    });
