Tower Param/Serializer API Ideas

params.js

// transform|parse|format|serialize, which one?
App.serialize('array').to(function(string) {
  return string.split(',');
}).from(function(array) {
  return array.join(',');
});

App.serialize('array', {
  to: function(string) {
    return string.split(',');
  },
  from: function(array) {
    return array.join(',');
  }
});

App.serialize('url', {
  to: function() {

  },
  from: function() {

  }
}).serialize('phone', {
  to: function(string) {
    string.replace(/asdf/, ...);
  }
});

App.type('phone', {
  to: function() {

  },
  from: function() {
    
  },
  // the reason you might not want to do this is b/c there
  // could be multiple types of validations for a phone, so keep
  // serializers and validators separate
  validate: function(value) {
    return !!this.to(value).match(/x/);
  }
});

App.param('digits', 'phone');
App.param('tags', 'array');
App.param('tags', {type: 'array'}).validate('in', ['ruby', 'javascript']);
App.param('tags', {type: 'array'}).validate(function(req) {
  if (req.isAdmin) return true; // maybe be able to search by different things based on role
  return ['ruby', 'javascript'];
});

App.Router = Tower.Router.extend({
  route: '/',
  action: function() {

  },
  posts: Tower.Route.extend({
    route: '/posts',
    index: Tower.Route.extend({
      route: '/',
      tags: Tower.param('tags'),
      title: App.Post.field('title') // maybe?
    })
  })
});

router.get('params') // bindable ember object
router.get('url') // bindable ember object

// 1. serialization
// 2. param/field
// 3. validation
