`.addRoomMembersToRooms()`

Subscribe all members of a room to one or more additional rooms.

sails.sockets.addRoomMembersToRooms(sourceRoom, destRooms, cb);

Usage

	Argument	Type	Details
1	sourceRoom	((string))	The room from which to retrieve members.
2	destRooms	((string)), ((array))	The room or rooms to which to subscribe the members of `sourceRoom`.
3	cb	((function?))	An optional callback, which will be called when the operation is complete on the current server (see notes below for more information) or if fatal errors were encountered. In the case of errors, it will be called with a single argument (`err`).

Example

In a controller action:

javascript

subscribeFunRoomMembersToFunnerRooms: function(req, res) {
  sails.sockets.addRoomMembersToRooms('funRoom', ['greatRoom', 'awesomeRoom'], function(err) {
    if (err) {return res.serverError(err);}
    res.json({
      message: 'Subscribed all members of `funRoom` to `greatRoom` and `awesomeRoom`!'
    });
  });
}

Notes

In a multi-server environment, the callback function (cb) will be executed when the .addRoomMembersToRooms() call completes on the current server. This does not guarantee that other servers in the cluster have already finished running the operation.
