MongoDb 聚合檢查 id 是否存在於對象數組中

Question

我已經寫了這個聚合，它工作正常

db.ParcelStatus.aggregate([{
     {
         $lookup: {
             from: "Parcel",
             localField: "parcelId",
             foreignField: "_id",
             as: "parcel"
         }
     },
     {
         $unwind: {
             path: "$parcel",
             preserveNullAndEmptyArrays: true
         }
     },
     {
         $lookup: {
             from: "ParcelStatus",
             localField: "parcel._id",
             foreignField: "parcelId",
             as: "parcel.parcelStatuses"
         }
     },
     {
         $lookup: {
             from: "Customer",
             localField: "parcel.customerData.customerId",
             foreignField: "_id",
             as: "parcel.customerData.customer"
         }
     },
     {
         $unwind: "$parcel.customerData.customer"
     }
 ])

現在在 PARCEL object 中包含的 ParcelStatus 數組中，我需要檢查一下

if(parcel.ParcelStatus.includes((x) => x.statusRepositoryId === 'ID's from frontend')
//then run $match on root against statusRepositoryId === 'SPECIFIC STATIC ID'

我不知道如何在聚合中做到這一點。 您的幫助將不勝感激

只需添加這個$match階段：

{
    $match: {
        "parcel.parcelStatuses.statusRepositoryId": {$in: idArrayFromClient}
    }
}
