Answer 1

What query do you want to write this way? It is possible to write nearly all queries using the CakePHP ORM. Using the query building functions of CakePHP is the prefered way of doing it.
All data fetching an manipulation should be done in a model as well. See Separation of Concerns.
Here is a complete model method to fetch an user record based on its id OR slug.
public function view($userId, $options = []) {
$defaults = array(
'contain' => array(),
'conditions' => array(
'OR' => array(
$this->alias . '.' . $this->primaryKey => $userId,
$this->alias . '.slug' => $userId,
),
$this->alias . '.email_verified' => 1
),
);
$result = $this->find('first', Hash::merge($defaults, $options));
if (empty($result)) {
throw new NotFoundException(__d('user_tools', 'User not found!'));
}
return $result;
}
Controller:
public function view($userId = null) {
$this->set('user', $this->User->view($userId);
}
Alternative but NOT preferred mode method to fetch te data
public function view($userId, $options = []) {
$result = $this->query(/* Your query here */);
if (empty($result)) {
throw new NotFoundException(__d('user_tools', 'User not found!'));
}
return $result;
}

Your solution is correct, let me eleborate it in more detail
1st Solution
In your controller
$arrayTemp =array();
$arrayTemp = $this->ModelName->query(' Your Query String ');
$this->set('post',$arrayTemp);
2nd Solution
In your model class
function returnDate(){
return $this->query('Your Query String')
}
In Controller class
$arrayTemp = $this->ModelName->returnDate();
$this->set('post',$arrayTemp);
}
