Question

能否请您告诉我为什么使用mongoos在MongoDB中插入许多无法正常工作的

这是我的代码 https://codesandbox.io/s/gallant-solomon-o91wp 它只插入一行，而不是多行

app.get("/saveData", async () => {
  try {
    const data = [
      {
        empid: "test123",
        date: "19-Jul-2019"
      },
      {
        empid: "test13",
        date: "18-Jul-2019"
      }
    ];
    console.log("before save");
    let saveBlog = await BlogPostModel.collection.insertMany(data, {
      checkKeys: false
    }); //when fail its goes to catch
    console.log(saveBlog); //when success it print.
    console.log("saveBlog save");
  } catch (error) {
    console.log(error);
  }
});

根据https://codesandbox.io/s/gallant-solomon-o91wp 这将不起作用，因为您的ID在架构中是唯一的，并且您尝试添加具有未定义ID的数据

// your data as per https://codesandbox.io/s/gallant-solomon-o91wp
const data = [
  {
    empid: "test123",
    date: "19-Jul-2019"
  },
  {
    empid: "test13",
    date: "18-Jul-2019"
  },

  {
    empid: "test13",
    date: "11-Jul-2019"
  }
];

解决方案如下更改数据

const data = [
  {
    id: "1",
    empid: "test123",
    date: "19-Jul-2019"
  },
  {
    id: "2"
    empid: "test13",
    date: "18-Jul-2019"
  },
  {
    id: "3"
    empid: "test13",
    date: "11-Jul-2019"
  }
];

使用mongoos插入许多在mongoDB中不起作用的东西
