I am attempting to use the subscribe function described here. However, when editing \/assets\/js\/app.js<\/code>, I am getting this error:<\/p>\n

Uncaught ReferenceError: Room is not defined \n<\/code><\/pre>\n
So, I am not entirely sure why, but it cannot find my model. Here is my code:<\/p>\n
Room.subscribe(req, [{id: \"5278861ab9a0d2cd0e000001\"}], function (response) {\n  console.log('subscribed?');\n  console.log(response);\n});\n<\/code><\/pre>\n

    You are mixing server side code with browser code. Sails only provides some extensions to the socket object that let you call your controllers easily. Here are the docs: link.<\/p>\n
    You need to handle your subscribtion inside your controllers and call them from the browser.<\/p>\n<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
