How to update model joined with belongsTo?

I have a Consultation model

export default DS.Model.extend({
   records: DS.hasMany('record', { async: true }),
   currentUser: DS.belongsTo('user'),
   remoteUser: DS.belongsTo('user'),
   created_time: DS.attr('number'),
   freeMsgCount: function () {
      return (this.get('remoteUser.msg_block')-this.get('user_msg_cnt'));
   }.property('user_msg_cnt'),
   .....
});

And User model

export default DS.Model.extend({
    name: DS.attr('string'),
    .....
});

And I try to update User model. I get json data via WebSocket

socket.on('message', function (jsonObj) {
    if (jsonObj.action && jsonObj.action == 'userReload') {
         self.store.push('user',jsonObj.userData );
         return;
    }
}

But Consultation model doesn't know about this update, because I have property freeMsgCount in Consultation model which is using data from User model this.get('remoteUser.msg_block'). User data was updated I saw it in Ember inspector. How can I tell Consultation model to update relation remoteUser?

It seems that you're not watching remoteUser changes in your computed property, so it won't be triggered if remoteUser property's changed. Please add remoteUser.msg_block to computed property declaration:

export default DS.Model.extend({
   # ...
   freeMsgCount: function () {
      return (this.get('remoteUser.msg_block')-this.get('user_msg_cnt'));
   }.property('user_msg_cnt', 'remoteUser.msg_block'),
