[英]Sorting inside a document in Yii2 mongodb
I am doing an application with Yii2 and mongodb.I want to retrieve records of a client based on id and sort the events of that client by date in descending order.But my code is not working.Please help me to find the issue. 我正在使用Yii2和mongodb进行应用程序。我想根据id检索客户端的记录,并按日期降序对该客户端的事件进行排序。但是我的代码无法正常工作,请帮助我找到问题。
The 'client' Collection's document is given below “客户”集合的文档如下
{
"_id" : ObjectId("55c397646ac8e41812000029"),
"name" : "Krishnapriya",
"location" : "Karunagapalli",
"address" : "",
"phoneno" : [
"8765456789"
],
"email" : [
"kp@gmail.com"
],
"category" : "0",
"notes_on_user" : "",
"event" : [
{
"event_title" : "Sony Home Theater",
"event_call_or_visit_purpose" : "2",
"event_notes" : "She enquired about new Sony XXX 5.1 Channel Home theater",
"event_call_or_visit" : "1",
"event_datetime" : ISODate("2015-08-06T17:23:46.000Z")
},
{
"event_title" : "San Disk Pendrive",
"event_call_or_visit_purpose" : "1",
"event_notes" : "She wants the pendrive to be repaired by 2 days",
"event_call_or_visit" : "2",
"event_datetime" : ISODate("2015-08-06T17:31:07.000Z"),
"item" : {
"item_name" : "San Disk 4gb",
"item_model" : "San disk",
"item_description" : " Pendrive not in reading condition",
"item_accessories" : []
}
}
]
}
Here I want to get the document's 'event' array sorted with 'event_datetime' field in descending order .My controller code is given below. 在这里,我想获取文档的'event'数组,并以'event_datetime'字段降序排列。我的控制器代码如下。
$clientdetail = Yii::$app->mongodb->getCollection('client');
$result = $clientdetail->find(["_id" =>$id])->sort(["event.event_datetime"=> -1]);
Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
return $result;
$query = Customer::find()->addOrderBy(['name'=> SORT_DESC, 'email' => SORT_DESC]);
$arrayDataProvider = new ArrayDataProvider([
'allModels' => $query->all(),
'pagination' => ['pageSize' => 20],
]);
It works 有用
