雄弁なモデル を使用します
class Category extends Model
{
protected $table = 'tbl_form'; // 'posts'
public function posts()
{
return $this->hasMany(Post::class, 'category', 'category')->select(['title']);
}
}
class Post extends Model
{
protected $table = 'tbl_form'; // 'posts'
public function category()
{
return $this->belongsTo(Category::class, 'category', 'category');
}
}
そして、そのように取得します:
$categories = Category::all();
dd($categories[0]->posts);
