私は、グループごとに実行していて、熱心な負荷で注文しています。Laravel eloquent order by eager loading
Message::whereIn('conversation_id',$msgs)
->where('deleted', '!=', $userId)
->with(array('last_sender' =>function($query) use ($userId){
$query->where('id','!=', $userId);
$query->select('id', 'userName', 'profilePic','firstName', 'lastName');
}))
->with(array('last_reciever' =>function($query) use ($userId){
$query->where('id','!=', $userId);
$query->select('id', 'userName', 'profilePic','firstName', 'lastName');
}))
->orderBy('id', 'desc')
->orderBy('conversation_id', 'desc')
->groupBy('id')
->groupBy('conversation_id')
->get();
それはこの
{
"data": [
{
"id": 133,
"conversation_id": 13,
"last_sender": null,
"last_reciever": {
"id": 55,
"userName": "buyer",
"profilePic": "pRBDBFJW55baSnF560Ajid8jTgPo5kmg4i5LMhPG.jpeg",
"firstName": "Matti",
"lastName": "Rames"
},
"msg": "second message 2 to user second",
"attachment": null,
"deleted": 0,
"seen": 0,
"created_at": "2017-10-17 15:43:14",
"updated_at": "2017-10-17 15:43:14"
},
{
"id": 132,
"conversation_id": 11,
"last_sender": null,
"last_reciever": {
"id": 54,
"userName": "Sadek",
"profilePic": "Nir7zgorNT2dmwcXJdhNK3ZmPAltmkEnj0SXDCDC.png",
"firstName": "Sadek",
"lastName": "Hossain"
},
"msg": "second message to first user",
"attachment": null,
"deleted": 0,
"seen": 0,
"created_at": "2017-10-17 15:38:16",
"updated_at": "2017-10-17 15:38:16"
},
{
"id": 131,
"conversation_id": 13,
"last_sender": null,
"last_reciever": {
"id": 55,
"userName": "buyer",
"profilePic": "pRBDBFJW55baSnF560Ajid8jTgPo5kmg4i5LMhPG.jpeg",
"firstName": "Matti",
"lastName": "Rames"
},
"msg": "second message to second user",
"attachment": null,
"deleted": 0,
"seen": 0,
"created_at": "2017-10-17 15:37:49",
"updated_at": "2017-10-17 15:37:49"
},
{
"id": 130,
"conversation_id": 11,
"last_sender": null,
"last_reciever": {
"id": 54,
"userName": "Sadek",
"profilePic": "Nir7zgorNT2dmwcXJdhNK3ZmPAltmkEnj0SXDCDC.png",
"firstName": "Sadek",
"lastName": "Hossain"
},
"msg": "Hi how are you",
"attachment": null,
"deleted": 0,
"seen": 0,
"created_at": "2017-10-17 15:36:49",
"updated_at": "2017-10-17 15:36:49"
}
]
}
のようなデータを返します。しかし、私は最初の2つの最新の結果を返すようにしたいです。 id 133
と132
私は->groupBy('id')
を追加しましたが、ここでは役に立たず、すべてのレコードを返すことを知っています。私はちょうど私のデータが何であるかを示すためにそれを加えました。だから->groupBy('id')
を取り除いた場合は、idが131
となり、130
助けてください。ありがとうございました。
