Hide some properties in JSON response object in sails.js

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?

Overwrite the toJSON() function of your model. This can also be used to hide other sensitive data.

module.exports = {
    attributes: {
        name: 'string',
        email: 'email',
        token: 'string',
        toJSON: function() {
            var obj = this.toObject();
            delete obj.token;
            return obj;
        }
    }
}
