use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;  

class Post extends Model
{
    use HasFactory;
    public $table = "posts";
      
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'id', 'title', 'body', 'status'
    ];
    /**
     * Scope a query to only include popular users.
     *
     * @param \Illuminate\Database\Eloquent\Builder $query
     * @return \Illuminate\Database\Eloquent\Builder
     */
    public function scopeToday($query)
    {
        return $query->whereDate('created_at', \Carbon\Carbon::today());
    }
}
