Recently, I started exploring couchbase lite mobile sdk for iOS. The sync
server and gateway are also up and running. I am going through the couch
chat sample. There are few questions:
1. I am checking the basic authentication (CBLAuthentication). What is the
correct way to check authentication success ? Do we have to rely on the
status of push / pull replication as reported in the notification
corresponding to replication progress ? If Yes then which status should be
used for this ? If No then what is the other way to do this ?
2. I am trying to create a simple chat application in iOS swift whose data
model resembles that of couchchat. The database setup is also successful.
The replication is also accomplished. The chat room model is as below:
public class ChatRoom: CBLModel{ @NSManaged var title: String! @NSManaged
var channel_id: String! @NSManaged var owners: [String]! @NSManaged var
members: [String]!}
Is above model structure correct ?
Then I tried to create a chatroom based on loggedInusername & another user name
as in the function
public func chatRoom(forUser aUserName: String)->ChatRoom?{
let chatRoomTitleToMatch = loggedInUserName + "_" + aUserName
var chatRoom: ChatRoom? = nil
//myChatRoomsQuery is also created prior to its use here
if let existingChatRooms = myChatRoomsQuery?.rows{
while let aRow = existingChatRooms.nextRow() {
let existingRoom = ChatRoom(for: aRow.document!)
if (existingRoom?.owners.contains(loggedInUserName)) == true ||
(existingRoom?.owners.contains(aUserName)) == true{
chatRoom = existingRoom
break
}
}
}
if chatRoom == nil {
let aNewChatRoom = ChatRoom(forNewDocumentIn: self.database!)
aNewChatRoom.title = chatRoomTitleToMatch
aNewChatRoom.owners = [loggedInUserName,aUserName]
aNewChatRoom.members = aNewChatRoom.owners
aNewChatRoom.channel_id = aNewChatRoom.document?.documentID
aNewChatRoom.type = "room"
do{
try aNewChatRoom.save()
}catch{
print("Encountered error: \(error) while saving chat room.")
}
chatRoom = aNewChatRoom
}
return chatRoom
}
But the room is not getting saved. Also there is no error returned in the save
operation. What can be the probable issue ? The application has successfully
connected to the database & push / pull replication has also occured.
I have also registered the above model class (ChatRoom) as below:
fileprivate func registerModelClasses(){
self.database?.modelFactory?.registerClass("UserProfile", forDocumentType:
"profile") self.database?.modelFactory?.registerClass("ChatRoom",
forDocumentType: "room")}
