Laravel : Data not inserted on the table - laravel

Question

Facing a problem on submit form data.
When I fill up all form data then it is inserted into the database. But when I fill only mandatory field data and leave other data as blank it is not working and it redirect to the same form.
On removing validation also not working.
My controller function code:
public function save(Request $request) {
try {
$validator = Validator::make($request->all(), Activity::rules());
$activity = Activity::saveOrUpdate($request);
if($activity !== false) {
return redirect()->route('lists-activity')->with('success', trans('activity data added successfully.!!'));
} else {
return back()->with('error', "Unable to save activity data.!!")->withInput();
}
} catch (\Exception $ex) {
return back()->with('error', "Unable to save activity data.!!")->withInput()->withErrors($validator);
}
}
My model code :
namespace App;
use Illuminate\Http\Request;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Input;
class Activity extends Model
{
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = [
'category_id',
'title',
'description',
'country_id',
'city_id',
'latitude',
'longitude',
'addressOne',
'addressTwo',
'hours_recomended',
'hours_fixed',
'time_fixed',
'start_time',
'end_time',
'file_type',
'flag_image'
];
/**
* Indicates if the model should be timestamped.
*
* #var bool
*/
public $timestamps = false;
public static function rules() {
return [
'category_id' => 'required',
'title' => 'required|string|max:255',
'country_id' => 'required',
'city_id' => 'required',
'hours_fixed' => 'required',
'start_time' => 'required',
'end_time' => 'required'
];
}
public static function saveOrUpdate(Request $request) {
try {
$id = $request->get('id', false);
$activity = false;
DB::transaction(function () use ($request, &$activity, $id) {
$activity = $id ? Activity::findOrFail($id) : new Activity();
$activity->fill($request->all());
try {
$activity->save();
} catch (\Exception $ex) {
throw $ex;
}
});
return $activity;
} catch (\Exception $ex) {
throw $ex;
}
} }
Form view :
Don't know what I am doing wrong?

Looks like validation works and redirects back as it supposes to do.
Put {{ dump($errors->all()) }} to the view and you'll see errors in the form after submitting the form.
Also, use the updateOrCreate() which does exactly what you're trying to do and will help you to avoid errors:
public static function saveOrUpdate(Request $request) {
return $this->updateOrCreate(['id' => $request->id], $request->all());
}
