Sailsjs: How do I transform a POST request's body/fields for the REST API

It is awesome how sails will automatically generate a REST API for me. But, how can I add extra processing to a REST route? For example, I might have a POST /users route to create new users and it accepts a password as one of the attributes for the users model. But, I wouldn't want to store passwords as-is; rather I would want to hash passwords and salt them for better security. Is there a way to write code before the REST API handles the request so that way I can transform the input or do some kind of processing in general if need be?

You can implement beforeValidate or beforeCreate method under your user model Check out the doc here http://www.sailsjs.org/#!/documentation/concepts/ORM/Lifecyclecallbacks.html

I use this for hash password : 

/**
 * User.js
 *
 * @description :: TODO: You might write a short summary of how this model works and what it represents here.
 * @docs        :: http://sailsjs.org/#!documentation/models
 */
module.exports = {
  attributes   : {
    name     : 'string',
    password : {
      type      : 'string',
      required  : true,
      minLength : 6
    },
    email    : {
      type     : 'email',
      unique   : true,
      required : true
    },
    toJSON   : function ()
    {
      var obj = this.toObject();
      delete obj.password;
      return obj;
    }
  },
  beforeCreate : function (attrs, next)
  {
    var bcrypt = require('bcrypt');

    bcrypt.genSalt(10, function (err, salt)
    {
      if (err)
      {
        return next(err);
      }

      bcrypt.hash(attrs.password, salt, function (err, hash)
      {
        if (err)
        {
          return next(err);
        }

        attrs.password = hash;
        next();
      });

    });
  }
};
