.publishCreate( data,[request] )

Purpose

PublishCreate doesn't actually create anything. It simply publishes information about the creation of a model instance via websockets. PublishCreate is called automatically by the blueprint create action.

The default implementation of publishCreate only publishes messages to the firehose, and to sockets subscribed to the model class using the watch method. It also subscribes all sockets "watching" the model class to the new instance. The socket message to subscribers will include the following properties:

• id - the id attribute of the new model instance
• verb - "created" (a string)
• data - an object-- the attributes and values of the new model instance

data

An object containing the attributes and values of the new model instance.

request

If this argument is included then the socket attached to that request will not receive the notification.

Example Usage

UsersController.js

module.exports = {

  testSocket: function(req,res){

        var nameSent = req.param('name');

        if (nameSent && req.isSocket){

          User.create({name:nameSent}).exec(function created(err,newGuy){
            User.publishCreate({id:newGuy.id,name:newGuy.name});
            console.log('A new user called '+newGuy.name+' has been created');
          });

        } else if (req.isSocket){

          User.watch(req);
          console.log('User with socket id '+sails.sockets.id(req)+' is now subscribed to the model class \'users\'.');

        } else {

          res.view();

        }
    }
}

    // Don't forget to handle your errors

views/users/testSocket.ejs

<script type="text/javascript">
window.onload = function subscribeAndListen(){
    // When the document loads, send a request to users.testSocket
    // The controller code will subscribe you to the model 'users'
    socket.get('/users/testSocket/');

    // Listen for the event called 'user' emited by the publishCreate() method.
    socket.on('user',function(obj){
      if (obj.verb == 'created') {
         var data = obj.data;
         console.log('User '+data.name+' has been created.');
      }
    });
};

function makeNew(){

    // Send the new users name to the 'testSocket' action on the 'users' controller

    socket.get('/users/testSocket/',{name:'Walter'});
}

</script>
<div class="addButton" onClick="makeNew()">Click Me to add a new 'Walter' ! </div>
