Re: Problem with hasMany

I don't suggest that you modify the core files like that. It will lead
to problems down the road when you want to upgrade. The hint to put
the debug statements in there was just that--for debugging. It would
be better to track down precisely what the problem is in your own
code. The thing is, I'm having some trouble understanding what it is
you did.

if(!isset($this->alias) || empty($this->alias))
{ die('Es $this->alias'); }
if(!isset($model) || empty($model))
{ die('Is $this->{$model} = "'. $model . '" on
' . $this->alias); }

Is $this->{$model} = "" on Contenido

So, $model is empty. But, die(debug($this->{$model})); gives you a
nice bunch of information. So, I'm confused. Maybe I'm not the best
person to investigate this.

One thing: Grupos_de_contenido should *maybe* be GruposDeContenido.
I've no idea if it's related.
