javascript - Sails js subscribe to model changes scoped by groupid attribute -

i have model named groupfeed looks this

module.exports = {    schema:true,   attributes:    {     groupid:     {         model:'groups',         required:true     },      postid:      {         model:'post',         required:true     },      objectid:      {         model:'objects',         required:true     },   } }; 

on client side can subscribe groupfeed model using

io.socket.get('/groupfeed') 

which done automatically blueprint api ,

io.socket.on('groupfeed',function(obj){console.log(obj)}) 

would give me updates on model changes when publish on backend using

groupfeed.publishcreate({id:4,groupid:6,postid:2,objectid:1}) 

---

what want :-

i want client subscribe groupfeeds particular groupid. eg: user x can subscribe groupfeeds groupid 1 (note: group model stores user membership group )

or imaginary call:

io.socket.get('/groupfeed?groupid=5') 

so when call publishcreate groupid:5, people subscribed groupid 5's groupfeed update

you better create different rooms groups.

code untested! create controller: notificationscontroller.js

module.exports = {      subscribe: function(req, res) {         // groupid of user method         .....         .....         var roomname = 'group_' + groupid;         sails.sockets.join(req.socket, roomname);         res.json({             room: roomname         });     } } 

somewhere can create notification:

var roomnameforgroup = 'group_' + groupid; sails.sockets.blast(roomnameforgroup, {id:4,groupid:6,postid:2,objectid:1}); 

and in view:

io.socket.on('connect', function(){     io.socket.get('/notifications/subscribe', function(data, jwr){         if (jwr.statuscode == 200){             io.socket.on(data.room,function(obj){                 console.log(obj);             });         } else {             console.log(jwr);         }     }); }); 

i can not test code right now, looks workable.
