How do I query data in CakePHP using HABTM relationships and translation? - cakephp

Question

I'm using Cakephp and try to make my model to ActAs 'Translation'. But i have a problem.
My Client model relations are:
public $belongsTo = array("User");
public $hasAndBelongsToMany = array(
'Category' =>
array(
'className' => 'Category',
'joinTable' => 'categories_clients',
'foreignKey' => 'client_id',
'associationForeignKey' => 'category_id',
'unique' => true,
),
);
In Category Model:
public $name = 'Category';
public $hasMany = array(
'Product'
);
public $displayField = 'title';
public $recursive = 1;
public $actsAs = array(
'Tree',
'Translate' => array(
'title',
'alias',
'description',
),
'Containable' => array('CategoryTranslations'),
);
public $translateModel = 'CategoryTranslations';
public $translateTable = 'category_translations';
When i query from Client Controller to get all Client and relative Category, i can't get field "title", "alias" and "description" of Category. Here is my code:
if(isset($this->passedArgs['language_id'])){
$language_id = $this->passedArgs['language_id'];
}
else{
$language_id = Configure::read('Config.language_site');
}
$this->Client->Category->locale = $language_id;
$this->Client->recursive = 1;
$this->paginate = array('limit' => 20,'order' => array('User.id' => 'desc'));
$Clients = $this->paginate();
Here is result:
array(
'Client' => array(
'id' => '1',
'user_id' => '1',
'client_type' => 'tenderer',
'image' => null,
'image_list' => null,
'code' => 'SG0593',
'name' => 'Oorts',
'address' => '1000 Huynh Tan Phat',
'telephone' => '0987654321',
'fax' => '0983213434',
'email' => 'nguyentuandat.vn#gmail.com',
'proxy' => 'Dat Nguyen',
'position' => 'C.E.O',
'mobile' => '0987654321',
'referred_by' => 'noone',
'order' => null,
'status' => true,
'created' => '2014-03-27 00:00:00',
'modified' => '2014-03-27 00:00:00'
),
'User' => array(
'password' => '*****',
'id' => '1',
'username' => 'admin',
'group_id' => '1',
'gender' => 'Male',
'first_name' => 'Nguyễn',
'middle_name' => 'Tuấn',
'last_name' => 'Đạt',
'email' => 'nguyentuandat.vn#gmail.com',
'phone_number' => '([phone]',
'image' => '/uploads/images/255443_102754699884371_1177788671_n.jpg',
'status' => true,
'created' => '2014-01-16 09:26:09',
'modified' => '2014-01-22 06:47:25',
'full_name' => 'Nguyễn Tuấn Đạt'
),
'Category' => array(
(int) 0 => array(
'id' => '1',
'parent_id' => '0',
'type' => 'product',
'image' => '',
'order' => '0',
'status' => true,
'lft' => '1',
'rght' => '16',
'created' => '2014-01-25 00:00:00',
'modified' => '2014-01-25 00:00:00',
'CategoriesClient' => array(
'id' => '1',
'category_id' => '1',
'client_id' => '1'
)
)
)
)
Can you help me? Thank you!

Answer 1

Restructure the code
Unfortunately because of how behaviors work - that's none-trivial to solve exactly as asked.
You can however do something like this:
$Clients = $this->paginate();
// extract category ids in the results
$categoryIds = array_unique(Hash::extract($Clients, '{n}.Category.{n}.id'));
$categories = $this->Client->Category->find('all', array(
'conditions' => array(
'Category.id' => $categoryIds
)
));
// generate a category-id indexed array of categories
$categories = Hash::combine($categories, '{n}.Category.id', '{n}.Category');
// replace the untranslated category entries with translated category data
foreach($Clients as &$client) {
foreach($client['Category'] as &$cat) {
$id = $cat['id'];
$cat = $categories[$id];
}
}
This example is shown as pseudo controller code - you could also consider putting it in your Client afterFind method or a custom finder.

Answer 2

Thank for help.
I found a solution:
I added bellow code into AppModel->afterFind and it work fine
public function afterFind($results, $primary = false) {
if(!empty($this->hasAndBelongsToMany)) {
foreach($this->hasAndBelongsToMany as $model => $settings) {
if(isset($this->{$model}->actsAs['Translate'])) {
if(!empty($results[0][$model])) {
foreach($results as $k => $v){
foreach($results[$k][$model] as $row => $result) {
$supplement = $this->{$model}->find('first', array(
'conditions' => array(
$model .'.id' => $result['id']),
'fields' => $this->{$model}->actsAs['Translate'],
'recursive' => -1));
if(!empty($supplement)) {
$results[$k][$model][$row] = array_merge($results[$k][$model][$row], array_diff($supplement[$model], $result));
}
}
}// end foreach k=>v
}
}
}
}
return $results;
}
