Jeg har skrevet aggregeringsforespørgslen
db.session.aggregate([
{
$unwind:"$Sessions"
},
{
$unwind:"$Sessions.Conversations"
},
{
$unwind:"$Sessions.Conversations.Messages"
},
{
$match:{
"Sessions.Id" : "Session01",
"Sessions.Conversations.Messages.Direction":{
$in:[
"inbound", "outbound"
]
},
"Sessions.Conversations.Messages.Status":{
$in:[
"sent", "delivered"
]
}
}
},
{
$group:{
"_id":"$Sessions.Conversations.Id",
"Messages":{
$push:"$Sessions.Conversations.Messages"
}
}
}
]).pretty()
Output
{
"_id" : "Conversation02",
"Messages" : [
{
"Id" : "Message05",
"Status" : "sent",
"Direction" : "outbound"
}
]
}
{
"_id" : "Conversation01",
"Messages" : [
{
"Id" : "Message03",
"Status" : "delivered",
"Direction" : "inbound"
},
{
"Id" : "Message04",
"Status" : "sent",
"Direction" : "outbound"
}
]
}
Nu for at opdatere dokumentet:
Jeg har brugt positionelle filtre
db.session.update(
{},
{
$set:{
"Sessions.$[session].Conversations.$[].Messages.$[message].Status":"read"
}
},
{
"arrayFilters": [{"session.Id":"Session01"},{ "message.Id": "Message05" }]
}
)
Dette vil opdatere status som read
for "session.Id":"Session01"
og "message.Id": "Message05"
Håber dette vil hjælpe dig. :)
OPDATERING
db.session.update(
{},
{
$set:{
"Sessions.$[session].Conversations.$[].Messages.$[message].Status":"read"
}
},
{
"arrayFilters": [
{
"session.Id":"Session01"
},
{
"message.Direction": {
$in :[
"inbound",
"outbound"
]
},
"message.Status": {
$in :[
"sent",
"delivered"
]
}
}
]
}
)
