Answer 1

Create a provider by using this command

php artisan make:provider ProviderClassName

then define the callbacks for models in boot function

Model::created(function($model){
  //Do you want to do
});

List of available callbacks:

Model::creating(function($model){});
Model::updated(function($model){});
Model::updating(function($model){});
Model::deleted(function($model){});
Model::deleting(function($model){});
Model::saving(function($model){});
Model::saved(function($model){});
