为什么Collection.bulkwrite()只向mongodb数据库写入一个文档

Question

我已经使用ag网格构建了这个网格，我正在尝试通过单击saveInformation按钮将其数据存储在mongodb数据库中。

​

app.component.ts

saveInformation() {
    console.log('actionPlanPartiesrowData: ', this.actionPlanPartiesrowData);
    this.saveInformationService
    .saveActionPlanInformation(this.actionPlanPartiesrowData)
    .subscribe((response) => {
          console.log('INSIDE ACTION PLAN COMPONENT INSIDE SUBSCRIBE saveInformation');
          console.log('response: ', response);
    });
}

save-information.service.ts

  saveActionPlanInformation(actionPlanPartiesrowData
  ) {
    return this.http.post(`${this.uri}/fillActionPlan2`, actionPlanPartiesrowData, {
      responseType: "text"
    });
  }

在后端：

server.js

router.route('/fillActionPlan2').post((req, res) => {
    console.log('REQ.body of action plan is ', req.body);
    res.json('Action Plan data has been received on the server side')
    actionPlanRow.bulkWrite([{
        insertOne: {
            document: req.body[0]
        },
        insertOne: {
            document: req.body[1]
        },
        insertOne: {
            document: req.body[2]
        }
    }]).then(rest => {

        res.json(res.insertedCount, res.modifiedCount, res.deletedCount)
        console.log(rest.insertedCount, rest.modifiedCount, rest.deletedCount);
    });
})

下面是后端接收的数据: req.body：

Req.body：

REQ.body of action plan is  [ { project: 'row1 data',
    id: 'row1 data',
    riskId: 'row1 data',
    iso27001: 'row1 data',
    priority: 'row1 data',
    projectOwner: 'row1 data',
    estimatedCost: 'row1 data' },
  { project: 'row 2 data',
    id: 'row 2 data',
    riskId: 'row 2 data',
    iso27001: 'row 2 data',
    priority: 'row 2 data',
    projectOwner: 'row 2 data',
    estimatedCost: 'row 2 data' },
  { id: 'row 3 data',
    project: 'row 3 data',
    riskId: 'row 3 data',
    priority: 'row 3 data',
    iso27001: 'row 3 data',
    projectOwner: 'row 3 data',
    estimatedCost: 'row 3 data*' },
  {},
  {},
  {},
  {},
  {},
  {},
  {},
  {} ]

跑完后：

db.actionplanrows.find()

我总是只找到插入的最后一行：

{ "_id" : ObjectId("5d1899417fe11c05ecd9e7eb"), "id" : "row 3 data", "project" : "row 3 data", "riskId" : "row 3 data", "priority" : "row 3 data", "iso27001" : "row 3 data", "projectOwner" : "row 3 data", "estimatedCost" : "row 3 data*" }

我不明白为什么第一行和第二行不插入。为什么只执行最后一个insertOne()？

谢谢!

Answer 1

我不知道为什么大容量写入只插入最后一个文档。

我使用insertMany而不是以这种方式解决了这个问题：

actionPlanRow.insertMany([req.body[0], req.body[1], req.body[2], req.body[3], req.body[4]], {
    multi: true
}

希望这对某人有帮助：)
