    public function initialize()
    {
        $this->setSchema("public");
        $this->belongsTo('geonameid', 'Geoname', 'geonameid', array('alias' => 'Geoname'));
    }

    /**

    public function getGeoname($parameters = null)
    {
        return $this->getRelated('Geoname', $parameters);
    }
    ....

        $this->hasMany('geonameid', 'Admin1Codes', 'geonameid', array('alias' => 'Admin1Codes'));
        $this->hasMany('geonameid', 'Admin2Codes', 'geonameid', array('alias' => 'Admin2Codes'));

    }
  ....
}

$country->getGeoname(); //InvalidArgumentException: Parameter 'name' must be a string

All tables exists, this code runs on php 5.6 phalcon 2.8 without problems.
