MongoDBのシェルでダミーデータ作成

Posted at
InsertDummyData.js
/*
  MongoDBのシェルではJavaScriptが動きます。
  以下を必要に応じ変更してコピペすればダミーデータが作成できます。
  初期投入件数は10件です。
*/

for (var i=0; i<10; i++) {
  db.test.insert(
    {
      "id" : "id" + i, 
      "name" : i + "", 
      "comment" : "私は" + i + "郎です。" ,
      "created" : new Date(), 
      "updated" : new Date(), 
    }
  );
}

MongoDBのシェルにコピペして実行。

> for (var i=0; i<10; i++) {
...   db.test.insert(
...     {
...       "id" : "id" + i,
...       "name" : i + "郎",
...       "comment" : "私は" + i + "郎です。" ,
...       "created" : new Date(),
...       "updated" : new Date(),
...     }
...   );
... }

findで結果を見ると以下のようになる。

> db.test.find()
{ "_id" : ObjectId("5630e5466ed4cd5f7dbace78"), "id" : "id0", "name" : "0郎", "comment" : "私は0郎です。", "created" : ISODate("2015-10-28T15:09:58.479Z"), "updated" : ISODate("2015-10-28T15:09:58.479Z") }
