Retrieving data in Table class CakePHP 3.2 - cakephp

Question

I am using CakePHP 3.2
I am bit new to CakePHP. I am trying to get data from Icases table where the created date is within 10 days, but for some reason it's just returning the first row. Can anyone please let me know what I am doing wrong.
My Controller IcasesController
namespace App\Controller;
use App\Controller\AppController;
/**
* Icases Controller
*
* #property \App\Model\Table\IcasesTable $Icases
*/
class IcasesController extends AppController
{
public function index()
{
$case_count_data = $this->Icases->getCaseCountByAge();
print_r($case_count_data);
}
}
My Table class IcasesTable
namespace App\Model\Table;
use Cake\ORM\Query;
use Cake\ORM\RulesChecker;
use Cake\ORM\Table;
use Cake\Validation\Validator;
use Cake\ORM\TableRegistry;
use DateTime;
class IcasesTable extends Table
{
/**
* Initialize method
*
* #param array $config The configuration for the Table.
* #return void
*/
public function initialize(array $config)
{
parent::initialize($config);
$this->table('icases');
$this->displayField('name');
$this->primaryKey('id');
$this->belongsTo('Clients', [
'foreignKey' => 'client_id'
]);
$this->hasMany('Documents', [
'foreignKey' => 'icase_id'
]);
$this->belongsToMany('Users', [
'foreignKey' => 'icase_id',
'targetForeignKey' => 'user_id',
'joinTable' => 'icases_users'
]);
}

Answer 1

You should read and practice more according to CakePHP official Doc
public function getCaseCountByAge()
{
$casesTable = TableRegistry::get("Icases");
$query = $casesTable->find("all",['condition'=>['Icases.date_created >' => new DateTime('-10 days')]]);
$data = $query->execute();
return $data->fetch('assoc');
}
It could be very simple
public function getCaseCountByAge()
{
return $this->find("all",['condition'=>['Icases.date_created >' => new DateTime('-10 days')]])->all();
}
