Re: Problem with hasMany

If i only use die(debug($this->{$model})); I got the dump of object.
If i only use die(debug($this->alias)); I got the Grupos_de_contenido

It means what the error occurs is not in the first time what
getColumnType function is called. Then the die(debug($this->
{$model})); is killing the application before what the error occurs.

function getColumnType($column) {
$db =& ConnectionManager::getDataSource($this->useDbConfig);
$cols = $this->schema();
$model = null;

$column = str_replace(array($db->startQuote, $db->endQuote), '',
$column);

if (strpos($column, '.')) {
list($model, $column) = explode('.', $column);
}
if ($model != $this->alias && !empty($model) && isset($this->
{$model})) { // Line 948
return $this->{$model}->getColumnType($column);
}

I Added the lines:
if(!isset($model) || empty($model))
{ die('Is $this->{$model} = "'. $model . '" on
' . $this->alias); }

to know what values are in the variables ($this->alias, $this->
($model)) when the error occurs. I got:
Is $this->{$model} = "" on Contenido

Only I create a new not empty condition for $model, before try $this->
{$model} and all works fine.

Thanks again.
