Question

我正在以1000的批量插入数据。

我有这个功能来处理插入：

function insertInBatches(i, dataParsed, RecordModel, callback){
    var numberOfBatches = (Math.floor(dataParsed.length/1000)) + 1;
    console.log("Inserting batch #"+i +" out of: " +numberOfBatches);
    var batchedData = dataParsed.slice(i*1000, (i+1)*1000);
    console.log("Batched data: "+JSON.stringify(batchedData));
    RecordModel.insertMany(batchedData)
    .then(function(mongooseDocuments) {
         console.log("  - Insertion was successful.");
    })
    .catch(function(err) {
        callback("Error while inserting data to DB: "+err);
        return;
    })
    .done(function() {
        if (i==numberOfBatches-1){
            // Last iteration, all inserted successfully
            console.log("Insertion of: "+numberOfBatches+" batches was successful.");
            callback(null);
            return;
        }
        // Recursive calling to insert next batch
        console.log("Value of i: "+i);
        insertInBatches(++i, dataParsed, RecordModel);
        return;
    });
}

输出日志如下所示：

Model created. Inserting in batches.
Inserting batch #0 out of: 1
Batched data: [{"SCHID":"config","Priority":3,"DateCreated":"2016-08-04T13:22:04.443Z","Status":"queued","Json":{"EmailAddress":"oto@increase.dk","FirstName":"Ondrej","Age":"22"}},{"SCHID":"config","Priority":3,"DateCreated":"2016-08-04T13:22:04.443Z","Status":"queued","Json":{"EmailAddress":"lfr@increase.dk","FirstName":"Lenka","Age":"23"}}]
  - Insertion was successful.
Insertion of: 1 batches was successful.

但是当我从bash执行db.MainRecord.find()时，我看不到任何结果。

我的RecordModel是：{SCHID: String, Priority: Number, DateCreated: Date, Status: String, Json: mongoose.Schema.Types.Mixed};

db的路径：

 generalConfig.dbName = "test";
 generalConfig.recordsCollectionName = "MainRecords";
 generalConfig.schemaDefinition = {SCHID: String, Priority: Number, DateCreated: Date, Status: String, Json: mongoose.Schema.Types.Mixed};
 generalConfig.RecordSchema = new mongoose.Schema(generalConfig.schemaDefinition);
 generalConfig.RecordModel = mongoose.model(generalConfig.recordsCollectionName, generalConfig.RecordSchema, generalConfig.recordsCollectionName);

修改

我只需要重新启动服务器上的mongodb。不知道为什么。

EDIT2：

问题是我的愚蠢，我在错误的集合上找到了查找：MainRecord而不是MainRecords ......

函数insertMany已经完成而没有错误但没有插入任何内容，mongoose
