如何访问与另一个表Laravel 5.1相关的一列

Question

I have 3 models, Trials has one sample and track has one trial, I need to access sample name, I try to do this but get this error:

BadMethodCallException in Builder.php line 2024: Call to undefined method Illuminate\Database\Query\Builder::samples()

Controller:

public function track($id){
        $tracks = track::with('trials')->with('samples')->where('trials_id',$id)->get();

        return view('Tracks.index',compact('tracks'));
    }

Samples:

class samples extends Model
{
    protected $fillable = ['variety'];

    public function Trials()
    {
        return $this->belongsTo('App\trial');
    }

Trial:

class trial extends Model
{
    protected $fillable = ['amount','date','comments','code'];

    public function Samples()
    {
        return $this->hasOne('App\samples', 'id', 'samples_id');
    }

    public function Track()
    {
        return $this->belongsTo('App\track');
    }
}

Tracks:

class track extends Model
{
    public function Trials()
    {
        return $this->hasOne('App\trial', 'id', 'trials_id');
    }
}

Answer 1

Try it

$tracks = track::with('trials.samples')->where('trials_id',$id)->get();
