I'm getting an error when saving some empty text, textarea fields. Laravel forms this sql query:

```
SQLSTATE[HY000]: General error: 1366 Incorrect integer value: '' for column 'inside_area' at row 1 (SQL: insert into `ads` (`street`, `quarter`, `building_number`, `inside_area`, `price`, `admin_comment`, `valid_to`, `price_heating`, `rooms`, `floor_number`, `floors_number`, `kitchen_area`, `years`, `public_comment`, `video_url`, `3d_url`, `user_id`, `updated_at`, `created_at`) values (, , , , , , , , , , , , , , , , 1, 2017-03-13 14:33:50, 2017-03-13 14:33:50))

```

P.S. db table was created not in laravel way - I'm using existing tables, this may be important.

UPDATED: problem are only with INT fields, if they has empty form field on saving!

Table:

```
CREATE TABLE `ads` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `user_id` int(11) DEFAULT NULL,
  `ad_type_id` int(11) DEFAULT NULL,
  `city_id` int(11) DEFAULT NULL,
  `street` varchar(255) DEFAULT NULL,
  `quarter` varchar(255) DEFAULT NULL,
  `building_number` varchar(255) DEFAULT NULL,
  `inside_area` int(11) DEFAULT NULL,
  `price` int(11) DEFAULT NULL,
  `show_price_per_meter` int(1) DEFAULT NULL,
  `price_heating` int(10) DEFAULT NULL,
  `admin_comment` text,
  `valid_to` datetime DEFAULT NULL,
  `rooms` int(11) DEFAULT NULL,
  `floor_number` int(11) DEFAULT NULL,
  `floors_number` int(11) DEFAULT NULL,
  `kitchen_area` int(11) DEFAULT NULL,
  `balcony` int(1) DEFAULT NULL,
  `balcony_glazed` int(1) DEFAULT NULL,
  `years` int(11) DEFAULT NULL,
  `dyn_house_type_id` int(11) DEFAULT NULL,
  `dyn_heating_id` int(11) DEFAULT NULL,
  `dyn_installation_ids` int(11) DEFAULT NULL,
  `public_comment` text,
  `video_url` varchar(11) DEFAULT NULL,
  `3d_url` varchar(11) DEFAULT NULL,
  `available_for_trade` int(1) DEFAULT NULL,
  `created_at` timestamp NULL DEFAULT NULL,
  `updated_at` timestamp NULL DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

```

FORM:

```
{!! Form::open(['url'=>'ads']) !!}
    {!! Form::number('inside_area', null, ['class'=>'form-control']) !!}
{!! Form::close() !!}

```

Route:

```
Route::resource('ads', 'AdsController');

```

Save action:

```
public function store() {
        $input = Request::all();
        \App\Ad::create($input);
        return redirect('/ads/my_index');
    }

```

P.S.2 If I provide any value to `inside_area` field, it goes ok and the next error is for `price` field.
