Question

I have a relation hasMany but it doesn't work at my controller

code season model:

public function retro () {
    return $this->hasMany('App\Models\Retrocession','season_id');
}

code controller:

$hotelagencie = HotelAgency::find($id) ;
    $hotel = $hotelagencie->hotel;
    $season = $hotel->seasons;
    return  $season->retro

Ereur: Property [retro] does not exist on this collection instance.

Thxyou.

Answer 1

We confirmed what you want(Select all the retro from all the seasons), so I think I can give you an answer:

This is what you got:

$hotelagencie = HotelAgency::find($id) ;
    $hotel = $hotelagencie->hotel;
    $season = $hotel->seasons;
    return  $season->retro

This is what I think it needs to be:

$hotelagencie = HotelAgency::find($id) ;
    $hotel = $hotelagencie->hotel;
    $seasons = $hotel->seasons;
    return $seasons->pluck('retro');

For more info on what pluck() is and how to use it, please refer to the official docs:

I hope it helps;)
