Question

I have Cinema table & City table and I have relation with this tables by id.. and when I echo results i have PHP notice “Trying to get property of non-object”

What is the problem ? or I missed something ??

My Code:
Cinema model

public function relations()
{
    // NOTE: you may need to adjust the relation name and the related
    // class name for the relations automatically generated below.
    return array(
        'countryCode' => array(self::BELONGS_TO, 'TblCountry', 'country_code'),
        'city' => array(self::BELONGS_TO, 'TblCity', 'city_id'),
        'tblCinemaMovies' => array(self::HAS_MANY, 'TblCinemaMovies', 'cinema_id'),
        'tblDays' => array(self::HAS_MANY, 'TblDay', 'cinema_id'),
        'tblShowtimes' => array(self::HAS_MANY, 'TblShowtime', 'cinema_id'),
    );
}

City model

public function relations()
{
    // NOTE: you may need to adjust the relation name and the related
    // class name for the relations automatically generated below.
    return array(
        'tblCinemas' => array(self::HAS_MANY, 'TblCinema', 'city_id'),
        'countryCode' => array(self::BELONGS_TO, 'TblCountry', 'country_code'),
    );
}

<?php echo $model->city_id->name; ?>

Answer 1

<?php echo $model->city->name; ?>

You must use $model->city to get the corresponding city of the $model.
