如何使用多个索引将数据导入mongodb

Question

我对 mongodb 很陌生，我刚刚创建了一个 database 名称 Test 并且里面有一个 collection 称为 projects 我有一个包含 2 个这样的项目的 json 文件：

{
  "-KutvlMPRHGWWTgk1Mh4" : {
    "isPrivate" : true,
    "proj_contact" : "blMufEZjv6ZmnugDlTruzGwmowI3",
    "proj_creator" : "blMufEZjv6ZmnugDlTruzGwmowI3",
    "proj_date" : "01/01/2017",
    "proj_des" : "this is a testing projectasfasfasgasg",
    "proj_name" : "Project",
    "proj_pi" : "qCQee2pWGeN9PD3FRXbJpdN7mHT2"
  },
  "-KvARDkcsCEKZgnM94xH" : {
    "isPrivate" : false,
    "proj_autho" : [ "Lei0ohIcMBbzVtcQD1AgU4wHBKR2", "OnjEOFSNVpf189J9hAaSFWOZdl42", "0DwfVUeMAraiRxFZTa6xyjn6sfx2", "WHjFSvEo45U7ULzwIQdnUz6ytXp1", "kKTWt36bIifrRzpqNP1l2Gnl3KU2" ],
    "proj_contact" : "kKTWt36bIifrRzpqNP1l2Gnl3KU2",
    "proj_creator" : "kKTWt36bIifrRzpqNP1l2Gnl3KU2",
    "proj_date" : "10/12/2017",
    "proj_des" : "this is a test :)",
    "proj_name" : "another test",
    "proj_pi" : "qCQee2pWGeN9PD3FRXbJpdN7mHT2"
  }
}

所以我想将其导入projects collection。 我正在运行这个命令

mongoimport --db Test --collection projects --file import-file.json

但事情是我得到的结果是 mongodb 只创建 一个包含整个内容的索引 (1 id)。

我想要的是在导入之后，mongodb 将为上面的每个项目创建 2 个不同的索引（2 个 ids）

这是当前结果。我用的是 Studio 3T

谢谢

您似乎缺少一个花括号（嵌套对象本身）

{
  {"-KutvlMPRHGWWTgk1Mh4" : {
"isPrivate" : true,
"proj_contact" : "blMufEZjv6ZmnugDlTruzGwmowI3",
"proj_creator" : "blMufEZjv6ZmnugDlTruzGwmowI3",
"proj_date" : "01/01/2017",
"proj_des" : "this is a testing projectasfasfasgasg",
"proj_name" : "Project",
"proj_pi" : "qCQee2pWGeN9PD3FRXbJpdN7mHT2"
}},
{"-KvARDkcsCEKZgnM94xH" : {
"isPrivate" : false,
"proj_autho" : [ "Lei0ohIcMBbzVtcQD1AgU4wHBKR2", "OnjEOFSNVpf189J9hAaSFWOZdl42", "0DwfVUeMAraiRxFZTa6xyjn6sfx2", "WHjFSvEo45U7ULzwIQdnUz6ytXp1", "kKTWt36bIifrRzpqNP1l2Gnl3KU2" ],
"proj_contact" : "kKTWt36bIifrRzpqNP1l2Gnl3KU2",
"proj_creator" : "kKTWt36bIifrRzpqNP1l2Gnl3KU2",
"proj_date" : "10/12/2017",
"proj_des" : "this is a test :)",
"proj_name" : "another test",
"proj_pi" : "qCQee2pWGeN9PD3FRXbJpdN7mHT2"
 }}
}

更新：

By default, monogoimport assumes a special structure for a file to import from: similar to JSON format except that only one document per line is allowed with no comma after each of them

{
  "-KutvlMPRHGWWTgk1Mh4" : {
    "isPrivate" : true,
    "proj_contact" : "blMufEZjv6ZmnugDlTruzGwmowI3",
    "proj_creator" : "blMufEZjv6ZmnugDlTruzGwmowI3",
    "proj_date" : "01/01/2017",
    "proj_des" : "this is a testing projectasfasfasgasg",
    "proj_name" : "Project",
    "proj_pi" : "qCQee2pWGeN9PD3FRXbJpdN7mHT2"
  }
  "-KvARDkcsCEKZgnM94xH" : {
    "isPrivate" : false,
    "proj_autho" : [ "Lei0ohIcMBbzVtcQD1AgU4wHBKR2", "OnjEOFSNVpf189J9hAaSFWOZdl42", "0DwfVUeMAraiRxFZTa6xyjn6sfx2", "WHjFSvEo45U7ULzwIQdnUz6ytXp1", "kKTWt36bIifrRzpqNP1l2Gnl3KU2" ],
    "proj_contact" : "kKTWt36bIifrRzpqNP1l2Gnl3KU2",
    "proj_creator" : "kKTWt36bIifrRzpqNP1l2Gnl3KU2",
    "proj_date" : "10/12/2017",
    "proj_des" : "this is a test :)",
    "proj_name" : "another test",
    "proj_pi" : "qCQee2pWGeN9PD3FRXbJpdN7mHT2"
  }
}
