eg:

$parameters["order"] = "Pessoa.nome";
$pessoas = Pessoa::find($parameters);

foreach ($pessoas as $pessoa) {
    $usuario = $pessoa->getUsuario();

    echo $usuario->getLogin(); //Fatal error: Call to undefined method Phalcon\Mvc\Model\Resultset\Simple::getName() in...

}

//..............

foreach ($pessoas as $pessoa) {
    $usuario = $pessoa->getUsuario();

    echo $usuario->login; //Undefined property: Phalcon\Mvc\Model\Resultset\Simple::$login in...

}
  • phalcon 2.0.2
  • php 5.6

If your relation name is usuario, try

echo $pesoa->usuario->getLogin();

I tried this too, but it did not work

Could you please provide more the code (model and relationship configuration)?

It must be a hasOne relation instead of a hasMany relation

Further to what Andres said - you have the relationship set up between Pessoa and Usuario as a hasMany relationship. So a single instance of Pessoa has many related instances of Usuario. Because of this, you can't reference pessoa->usuario, because that refers to only a single instance. Changing the relationship to a hasOne will give you the relationship you want.

On an unrelated note, you don't need to override find() and findFirst() - all you're doing is calling the parent method anyway. Overriding doesn't break anything, it's just unneccessary.

Yes, that's it!

but this was changed? I get the feeling always used the mentioned way...

thanks!!!

thanks for you help!!!

but, in the case of 1-n?

suppose it was a case of one to many.

as it would be done?
