Grid with Laravel 5.3 looking for foreign keys

Hello. I have an application where I need to mount a grid with all the data in the produtos table. This table has foreign keys for two other tables, grupo and subgrupo . To mount my grid, I need the array with the products to have the group and subgroup id and all the other information contained in an array.

My method in the controller:

public function grid(){
    return \App\produto::all();
}

The product model has:

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

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

But I do not know how to build the grid using this. I need the return array to look something like this:

[
  {
  "codigo": 3,
  "grupo": [
    {
      "codigo": 1,
      "descricao": "Descrição do grupo"
    }    
  ],
  "subgrupo": [
    {
      "codigo": 1,
      "descricao": "Descrição do subgrupo"
    }
  ],
  "descricao": "1"
  }
]

In addition, as you may notice I needed to change the default "id" to "code", but this is already done. But I do not know if this could affect the search.

I searched before but did not find what I needed, or maybe I did not search the right thing for lack of knowledge of Laravel's used names. Can someone help me, please?

You can bring your relationship data through the collection using the with method of Eloquent ORM. Take a look at here in the documentation to understand better. In your case it would look something like this:

public function grid(){
    return \App\produto::with('grupo', 'subgrupo')->all();
}

Remembering that what will be returned from this function is not an array but rather a collection ( Illuminate\Database\Eloquent\Collection ). But, I think it's enough for you to iterate over and perform the operations you want.
