hasMany does not work properly

Question

good night!! I’m trying to launch data report(groups and networks) but it doesn’t work...the group model is like this:

function Redes(){
     return $this->hasMany('App\rede','grupo_id','id');
}

in the network model is like this:

class rede extends Model
{
  protected $table = "redes";
}

I’m trying to display the data like this:

Function Index(groups $groups, network $network){

    $lista = $grupos->all();
    foreach($lista as $li):

        foreach($li->Redes() as $d):
            print_r($d->id);
       endforeach;

    endforeach;
}

And nothing, what’s wrong? Thank you for your constant attention!!!
