Automatic Column Value When Creating Records in Laravel

Automatic Column Value When Creating Records in Laravel

If you want to generate some DB column value when creating record, add it to model's boot() method.
For example, if you have a field "position" and want to assign the next available position to the new record (like Country::max('position') + 1), do this.

class Country extends Model {

          protected static function boot()
           {
                       parent::boot();
                      // every new record will get next available position number
                      Country::creating(function($model) {
                           $model->position = Country::max('position') + 1;
                      });
          }
}
