Exacto, eso es bueno también. Como ejemplo te paso un código que
utilizo (tomado de [1] y ajustado un poco) obviamente tenes que
ajustarlo ;)
class SingleInheritanceAppModel extends AppModel{
var $__fields = array();
function __construct($id = false,$ignore_table = null, $ds = null)
{
$table = $this->__table;
parent::__construct($id,$table,$ds);
}
function findAll($conditions = null, $fields = null, $order = null,
$limit = null, $page = 1, $recursive = null)
{
if($conditions == null)
{
$conditions = $this->name. "." . $this->__type_field .
" = '" .
$this->__type_value . "'";
}
else
{
$conditions = $conditions . " AND " . $this->name . "."
.
$this->__type_field . " = '" . $this->__type_value . "'";
}
if($fields == null)
{
$fields = $this->__fields;
}
else
{
foreach($fields AS $field)
{
if(!array_search($field,$this->__fields))
{
throw new Exception("Field " . $field .
" does not exist in Model
" . $this->name);
}
}
}
return parent::findAll($conditions, $fields, $order, $limit,
$page,
$recursive);
}
function findCount($conditions = null, $recursive = 0)
{
if($conditions == null)
{
$conditions = $this->name . "." . $this->__type_field .
" = '" .
$this->__type_value . "'";
}
else
{
$conditions = $conditions . " AND " . $this->name . "."
.
$this->__type_field . " = '" . $this->__type_value . "'";
}
return parent::findCount($conditions, $recursive);
}
function findAllThreaded($conditions = null, $fields = null, $sort =
null)
{
if($conditions == null)
{
$conditions = $this->__table . "." .
$this->__type_field . " = '" .
$this->__type_value . "'";
}
else
{
$conditions = $conditions . " AND " . $this->name . "."
.
$this->__type_field . " = '" . $this->__type_value . "'";
}
if($fields == null)
{
$fields = $this->__fields;
}
else
{
foreach($fields AS $field)
{
if(!array_search($field,$this->__fields))
{
throw new Exception("Field " . $field .
" does not exist in Model
" . $this->name);
}
}
}
return parent::findAllThreaded($conditions, $fields, $sort);
}
function save($data = null, $validate = true, $fieldList = array())
{
$data[$this->name][$this->__type_field] = $this->__type_value;
return parent::save($data, $validate, $fieldList);
}
}
