Question

我有一个表，其中包含类似

的数据

 {
  _id: ....
  Name
  ...
 "RoomStatusDetails": [
 {
   "StatusEntryId": ObjectId("5bd6ea81d2ccda0a780054da"),
   "RoomId": "78163a07-76db-83c1-5c22-0749fab73251",
   "CurrentStatus": ObjectId("5bd17295d2ccda11f0007765"),
   "StartDate": ISODate("2018-10-09T22:00:00.0Z"),
   "Notes": "Notes for in service",
   "Discrepancy": "Discrepency",
   "Waiver": "Waiver",
   "TFlight": "T Flight",
   "IsActive": "Inactive" 
},
 {
   "StatusEntryId": ObjectId("5bd6ecf3d2ccda0a780054db"),
   "RoomId": "78163a07-76db-83c1-5c22-0749fab73251",
   "CurrentStatus": ObjectId("5bd17295d2ccda11f0007766"),
   "StartDate": ISODate("2018-10-16T22:00:00.0Z"),
   "Notes": "Out of service",
   "Discrepancy": "",
   "Waiver": "",
   "TFlight": "",
   "IsActive": "Active" 
    },
    ...
   }

我已经编写了以下几行代码，用于根据RoomId将IsActive字段更新为“ Inactive”

       $this->collection->updateOne(array('_id' => new MongoDB\BSON\ObjectID($this->id), "RoomStatusDetails" => 
                  array('$elemMatch' => array("RoomId" => $this->RoomId))),
                  array('$set' => array("RoomStatusDetails.$.IsActive" => 'Inactive')), array("multi" => true, "upsert" => false));

上面的代码未更新所有IsActive字段。请帮忙!!!

Answer 1

您必须使用arrayFilters来传递房间ID过滤器。如果没有arrayFilters，它将更新所有[]“ RoomStatusDetails”数组元素，而不考虑房间ID查询过滤器。

类似

 db.col.update(
   {"RoomStatusDetails.RoomId" :"78163a07-76db-83c1-5c22-0749fab73251"},
   {"$set":{"RoomStatusDetails.$[room].IsActive" : "Inactive"}}, 
   {"arrayFilters":{"room.RoomId":"78163a07-76db-83c1-5c22-0749fab73251"}}
);

在php中

$bulkbatchStatus->update(
  array('_id' => new MongoDB\BSON\ObjectID($this->id), "RoomStatusDetails" => array('$elemMatch' => array("RoomId" => $this->RoomId))), 
  array('$set' => array("RoomStatusDetails.$[room].IsActive" => 'Inactive')), 
  array("multi" => true, "upsert" => false, "arrayFilters" => array("room.RoomId" => $this->RoomId))
);

所有匹配的嵌入式文档：

要更新所有匹配的嵌入式文档，您应使用$[]，因为$是指匹配的嵌入式文档的第一位置。

位置$运算符充当第一个元素的占位符与查询文档匹配的

更新多个嵌入式文档不起作用
