accessing a parent of a parent relationship laravel

I am building an application in laravel in which each channel has some sections and you can post threads in the sections. I would like to access the channel from the thread. The hierarchy so far is this -channel --section ---threads

here are the three model classes

channel


use Illuminate\Database\Eloquent\Model;

class Channel extends Model
{
    public function users(){
        return $this->belongsToMany('App\User');
    }
    public function posts(){
        return $this->hasMany('App\Post');
    }
    public function isSubscribed($id){
        return $this->users()->find($id);
    }
    public function sections(){
        return $this->hasMany('App\Section');
    }
}

section

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

    public function threads(){
        return $this->hasMany('App\Thread');
    }
}

thread

{
    protected $fillable=['title','body','solved'];

    public function solutions(){
        return $this->hasMany('App\Solution');
    }
    public function comments(){
        return $this->hasMany('App\ThreadComment');
    }
    public function section(){
        return $this->belongsTo('App\Section');
    }
    public function arguments(){
        return $this->belongsToMany('App\Argument');
    }
    public function user(){
        return $this->belongsTo('App\User');
    }
    public function reports(){
        return $this->morphTo('App\Report','reportable');
    }
}

what I would like to do is to have a channel() method in thread class that makes me access the channel without having to do $thread->section->channel each time

If you don't have a problem using a package for this, use https://github.com/staudenmeir/eloquent-has-many-deep. You can have any levels of relationships.

Read the usage section of the package for details.

If you really want to, use an accesor.

public function getChannelAttribute()
{
    return $this->section->channel;
}
