I'm using this modified version of your sg.json config, this adds a
'user<N>-rooms' channel to each users admin_channels property, the chatroom
doc is added to each chatroom members -rooms channel.

var roomId = oldDoc.room;
var messageChannel = "room-" + roomId;
channel(messageChannel);
}
return;
}
if(doc.type == "chatroom") {
var roomId = doc._id;
var roomMembers = doc.members;
for (var i = 0; i < roomMembers.length; i++) {
var member = roomMembers[i];
channel(member + "-rooms");
}
var roomChannel = "room-" + roomId;
channel(roomChannel);
access(roomMembers, roomChannel);
} else if(doc.type == "message") {
// A user can only update its own messages
if(oldDoc) {
requireUser(oldDoc.user);
}
var roomId = doc.room;
var messageChannel = "room-" + roomId;
channel(messageChannel);
}
}
`
}
}
}
if I start a continuous changes feed:
curl -X GET
http://user1:user1@localhost:4984/couchbase-chat/_changes?feed=continuous
Then add a chatroom:
curl -X PUT http://user1:user1@localhost:4984/couchbase-chat/testchannel1
-d '{"members": ["user2","user1","user4"],"name": "still","type":
"chatroom","user": "user1"}' -H "Content-Type: application/json"
response:
{"id":"testchannel1","ok":true,"rev":"1-9bda027ae976eaec039a180fd16f3a8d"}
Then delete the chat room:
curl -X PUT http://user1:user1@localhost:4984/couchbase-chat/testchannel1
-d '{"_rev":"1-9bda027ae976eaec039a180fd16f3a8d","_deleted":true}' -H
"Content-Type: application/json"
response:
{"id":"testchannel1","ok":true,"rev":"2-e5851b5cb894cb7ff2badf951e21b3f5"}
I see both revisions now on the _changes feed:
{"seq":2,"id":"_user/user1","changes":[]}
{"seq":7,"id":"testchannel1","changes":[{"rev":"1-9bda027ae976eaec039a180fd16f3a8d"}]}
{"seq":8,"id":"testchannel1","deleted":true,"removed":["user1-rooms"],"changes":[{"rev":"2-e5851b5cb894cb7ff2badf951e21b3f5"}]}
