How to add description to a Doctrine_Record class - doctrine

Question

I have a table CustBillingEmployee described in the scheme below
CustBillingEmployee:
connection: doctrine
tableName: cust_billing_employee
columns:
employee_num:
type: integer(4)
fixed: false
unsigned: false
primary: true
autoincrement: false
job_title_code:
type: integer(4)
fixed: false
unsigned: false
primary: false
notnull: true
autoincrement: false
cost:
type: 'decimal(5, 2)'
fixed: false
unsigned: false
primary: false
default: '0.00'
notnull: true
autoincrement: false
relations:
HsHrEmployee:
local: employee_num
foreign: emp_number
type: one
and the class below
class cust_billing_employee extends Doctrine_Record
{
public function setTableDefinition()
{
$this->hasColumn('employee_num', 'integer',4,array(
'type' => 'integer',
'length' => 4,
'fixed' => false,
'unsigned' => false,
'primary' => true,
'autoincrement' => false,
));
$this->hasColumn('job_title_code', 'integer',4,array(
'type' => 'integer',
'length' => 4,
'fixed' => false,
'unsigned' => false,
'primary' => false,
'notnull' => true,
'autoincrement' => false,
));
$this->hasColumn('cost', 'decimal',5,array(
'fixed' => false,
'unsigned' => false,
'primary' => false,
'default' => '0.00',
'notnull' => true,
'autoincrement' => false,
));
}
public function setUp()
{
$this->hasOne('User', array(
'local' => 'employee_num',
'foreign' => 'emp_number'
));
}
public function __toString() {
return "HI";
}
}
When I try to extract a particular object like so:
echo Doctrine::getTable('CustBillingEmployee')->find(1);
I get an error
No description for object of class "CustBillingEmployee"
I was hoping that the function __toString() gets overridden from the parent class but that is not the case. How shall I add a description to the object then?
When displaying each record I want to be able to display employee name instead of just employee_num key and job title instead of job_title_cost

Answer 1

Can you post whole call stack, what code throws that error?
What is suspicious to me is the name of the class cust_billing_employee not being CustBillingEmployee and not extending BaseCustBillingEmployee which would be default behaviour of Symfony 1.4. Did you wrote this code 'by hand' ?
Since your schema is defined in schema.yml you should be using ./symfony doctrine:build-model task.
This should generate correct classes: CustBillingEmployee extending BaseCustBillingEmployee which extends sfDoctrineRecord and then Doctrine_Core::getTable('CustBillingEmployee')->find(1) should work perfectly.
Also note, that you should not touch BaseCustBillingEmployee as this is meant to be autogenerated code, all modifications (like __toString) should be done in CustBillingEmployee class.
