Collectionable Plugin
Introduction
This is a utility plugin for CakePHP. This helps managing find options, virtualFields and validations., (*1)
Setup
- Define $options(such a property name can be modified by configure) for Options Behavior
- Define $virtualFieldsCollection(such a property name can be modified by configure) for VirtualFields Behavior
- Define 'Validation'(such a config name can be modified by configure) section into Configure for ConfigValidationBehavior
- Define $validate{PatternName}, like $validateAdd, same structure with $validate, for MultiValidationBehavior
Sample code
OptionsBehavior
Here is a simple Post Model.
class Post extends AppModel {
var $hasMany = array('Comment');
var $hasOne = array('Status');, (*2)
var $acsAs = array('Collectionable.options');
var $defaultOption = true; // or string like 'default'
var $options =array(
'default' => array(
'contain' => array(
'Comment',
'Status',
),
'limit' => 10,
),
'published' => array(
'condtiions' => array('Status.published' => true),
),
'recent' => array(
'order' => ('Post.updated DESC'),
),
'rss' => array(
'limit' => 15,
),
'unlimited' => array(
'limit' => null,
),
'index' => array(
// You can do sub merging
'options' => array(
'published',
'recent',
),
),
);
}
You can use them by like:
class PostsController extends AppController {
function index() {
$this->paginate = $this->Post->options('index');
$this->set('posts', $this->paginate());
}, (*3)
function rss() {
$this->paginate = $this->Post->options('index', 'rss'); // multiple merging at run time;
$this->set('posts', $this->paginate());
}
function all_in_one_page() {
// you can use "options" attribute wihtin finding options
$posts = $this->Post->find('all', array('options' => array('index', 'unlimited')));
$this->set(compact('posts'));
}
}
To see more syntax, you would look at the test case or the code., (*4)
VirtualFieldsBehavior
This sample uses MatchableBehavior., (*5)
class User extends AppModel {
var $hasMany = array('Post');
var $actsAs = array('Collectionable.VirtualFields', 'Matchable');
var $virtualFields = array(
'full_name' => "CONCAT(User.first_name, ' ', User.last_name)",
);
var $virtualFieldsCollection = array(
'posts_count' => 'COUNT(Post.id)',
'amount_used' => 'SUM(Post.volume)',
);
}
You can use them by like:, (*6)
class UsersController extends AppController {
function admin_index() {
// Hey, you may feel like using OptionsBehavior :P
$jointo = array('Post');
$group = 'User.id';
$virtualFields = array('posts_count', 'amount_used'); // key of collections
$this->paginate = compact('jointo', 'group', 'virtualFields');
$this->set('users', $this->paginate());
}
function profile() {
$virtualFields = array('full_name' => false); // disable virtualFields
$user = $this->User->find('first', compact('virtualFields'));
$this->set(compact('user'));
}
}
ConfigValidationBehavior
class User extends AppModel {
var $actsAs = array('Collectionable.ConfigValidation');
var $validate = array(
'nickname' => array(
'required' => array(
'rule' => array('notempty'),
),
'min' => array(
'rule' => array('minlength'),
'message' => 'I said more than %s!!',
),
),
'email' => array(
'required' => array(
'rule' => array('notempty'),
),
'among' => array(
'rule' => array('between'),
),
),
);
}
You can set validation parameters, messages from Configuration:, (*7)
Configure::write('Validation', array(
'parameters' => array(
'User' => array(
'nickname' => array(
'min' => 3,
),
'email' => array(
'among' => array(16, 256)
),
),
),
'messages' => array(
'default' => array(
'required' => 'you need to enter.',
'min' => '%s characters needed',
),
'User' => array(
'email' => array(
'required' => 'are you kidding me or misreading?',
),
),
),
));
Note that priority is "hard coded on your model" > "specifying Model and field" > "default".
But if you turn $overwrite property on, "specifying Model and field" forces to overwrite("default" does not)., (*8)
MultiValidationBehavior
class User extends AppModel {
var $actsAs = array('Collectionable.MultiValidation');
var $validate = array(
'password_raw' => array(
'required' => array(
'rule' => array('notempty'),
),
'minlength' => array(
'rule' => array('minlength', 6),
),
),
);
// note that $validateprofile is invalid with 'profile'
var $validateProfile = array(
'nickname' => array(
'required' => array(
'rule' => array('notempty'),
),
'maxlength' => array(
'rule' => array('maxlength', 40),
),
),
);
var $validateRequireEmail = array(
'email' => array(
'required' => array(
'rule' => array('notempty'),
),
'email' => array(
'rule' => array('email'),
),
),
);
var $validatePasswordConfirm = array(
'password_confirm' => array(
'required' => array(
'rule' => array('notempty'),
),
'confirm_password' => array(
'rule' => array('confirm_password'),
),
),
);
// You can set validation pattern on demand:
function add($data, $validate = true, $options = array()) {
$this->useValidationSet('requireEmail');
$this->create();
return $this->save($data, $validate, $options);
}
// You can dsiable default $validate with second argument as false:
function edit($data, $validate = true, $options = array()) {
$this->useValidationSet('profile', false);
return $this->save($data, $validate, $options);
}
// You can specify two and more rule sets. these will be merged
function resetEmail($data) {
$this->useValidationSet(array('requireEmail', 'passwordConfirm'));
}
function confirm_password() {
// confirm password
}
}
