Using virtual fields in cakePHP 2.x

Albert picture Albert · Jan 31, 2013 · Viewed 10.5k times · Source

I've read through the documentation and struggled to understand what to do. Also, I've read through the questions here on stackoverflow, and nothing that I tried helped.

I've got a drop down that I want to list all employees in the company. The list should be displayed like this:

Name Surname (Job Title)

In my Model, I have this piece of code:

public $virtualFields = array(
    'fullname' => 'CONCAT(HrEmployee.name, " ", HrEmployee.surname, " (", HrEmployee.jobTitle, ")")'
);

And in my controller, I have this:

$hrEmployees = $this->User->HrEmployee->find('fullname',
    array(
        'fields' => array('HrEmployee.name','HrEmployee.surname','HrEmployee.jobTitle'),
        'order' => array('HrEmployee.name'=>'ASC','HrEmployee.surname'=>'ASC')
));

But I get this error:

Error: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'AS `User__fullname` FROM `intraweb_db`.`users` AS `User` WHERE `User`.`hr_emp' at line 1

What must I change? I can see that it's building the query, but it's changing it horribly bad...

Can anyone assist?

Cool so I fixed it. Partially thanks to Brandon for pointing me in the right direction.

Because of the virtual fields limitation, I had to do the workaround.

So, in my HrEmployee model I did this:

public $virtualFields = array(
    'fullname' => 'CONCAT(HrEmployee.name, " ", HrEmployee.surname, " (", HrEmployee.jobTitle, ")")'
);

And in my User model, I changed it to this:

class User extends AppModel {
public function __construct($id = false, $table = null, $ds = null) {
    parent::__construct($id, $table, $ds);
    $this->virtualFields['fullname'] = $this->HrEmployee->virtualFields['fullname'];
}

And lastly, in my UsersController, I just changed it a bit:

$hrEmployees = $this->User->HrEmployee->find('list',
    array(
        'fields' => array("id","fullname"),
        'order' => array('HrEmployee.name ASC','HrEmployee.surname ASC')
));
