Retrieving relationships of relationships using Eloquent in Laravel

Question

I have a database with the following tables and relationships:

Advert 1-1 Car m-1 Model m-1 Brand

If I want to retriev

Answer 1

First you need to create your relations,

belongsTo('Car');
    }

}

class Car extends Eloquent {

    public function model()
    {
        return $this->belongsTo('Model');
    }

}

class Model extends Eloquent {

    public function brand()
    {
        return $this->belongsTo('Brand');
    }

    public function cars()
    {
        return $this->hasMany('Car');
    }

}

class Brand extends Eloquent {

    public function models()
    {
        return $this->hasMany('Model');
    }

}

Then you just have to access this way:

echo Advert::find(1)->car->model->brand->name;

But your table fields shoud be, because Laravel guess them that way:

id (for all tables)
car_id
model_id
brand_id

Or you'll have to specify them in the relationship.
