Crear un Form Request

Su nomenclatura es (Nombre-del-modelo-que-impacta)+(Acción)+Request. Por ejemplo, si quieres crear un Form Request para validar los datos que actualizarán el modelo Post, deberías ponerle el siguiente nombre:

$ php artisan make:request PostCreateRequest

---

Crear un modelo

$ php artisan make:model User

// Produce error:

use App\Image;
use GImage\Image;

// Dar un alias para solucionar el error:

use App\Image;
use GImage\Image as GIImage;

---

Crear relaciones en el modelo

Si tenemos las siguiente estructura de tabla:

• shops
  • id
  • name
• products
  • id
  • name
• product_shop
  • product_id
  • shop_id

// Option 1
class Shop extends Model {
  /**
   * The products that belong to the shop.
   */
  public function products() {
    return $this->belongsToMany('App\Product');
  }
}

// Option 2
class Product extends Model {
  /**
   * The shops that belong to the product.
   */
  public function shops() {
    return $this->belongsToMany('App\Shop');
  }
}

// Use 
Shop::find($id)->with('products');

Si tenemos la siguiente estructura

• Persons
  • id
  • name
  • profession_id
• Professions
  • id

class Person extend Models {
  public function profession() {
    return $this->belongsTo(Profession::class);
