I'm very new to sails.js framework. I want to hide some particular fields in the response JSON object when it gets queried.

For example, I have a model object User:

```
User: {
  name: 'Paul',
  email: 'paul@gmail.com',
  token: 'sdffsdf',
  id: 1
}

```

I want hide "token" property in case if this user is queried by GET request: `localhost:1337/user?id=1`

Can somebody give me a hint how to do that?
