Mongodb $推入嵌套数组
Mongodb $推入嵌套数组
提问于 2019-02-21 06:27:01
我想在嵌套数组中添加新数据
我的文件是：
{
"username": "erkin",
"email": "erkin-07@hotmail.com",
"password": "b",
"playlists": [
{
"_id": 58,
"name": "asdsa",
"date": "09-01-15",
"musics": [
{
"name": "INNA - Cola Song (feat. J Balvin)",
"duration": "3.00"
},
{
"name": "blabla",
"duration": "3.00"
}
]
}
]
}
我想在此播放列表部分添加音乐：
{
"username": "erkin",
"email": "erkin-07@hotmail.com",
"password": "b",
"playlists": [
{
"_id": 58,
"name": "asdsa",
"date": "09-01-15",
"musics": [
{
"name": "INNA - Cola Song (feat. J Balvin)",
"duration": "3.00"
},
{
"name": "blabla",
"duration": "3.00"
},
{
"name": "new",
"duration": "3.00"
}
]
}
]
}
这是我尝试过的：
$users->update(
array(
'_id' => new MongoId (Session::get('id')),
'playlists._id' => $playlistId
),
array(
'$push' => array('playlists.musics' => array(
'name' => 'newrecord',
'duration' => '3.00'
))
)
);

可能是这样的，ID就是你的ObjectId。第一个{}是识别您的文档所必需的。只要您的集合中有另一个唯一标识符，就不需要使用ObjectId。
db.collection.update(
{ "_id": ID, "playlists._id": "58"},
{ "$push":
{"playlists.$.musics":
{
"name": "test name",
"duration": "4.00"
}
}
}
)
