I'm using Laravel 5 and would like to know if after modifying an attribute of a model, you can retrieve it.

For example:

 $usuario = Usuario::where(['nome' => 'Wallace'])->first();

 $usuario->nome = 'Guilherme';

In the example above, I modified the nome attribute of the model. I would like to know if you can retrieve the nome attribute. Does Laravel "save" the original value somewhere before saving changes?

Of course I could do this by doing another query, but I do not think that is the best way. So I will not accept answers of the type.

I would like to know if there is any way to retrieve the initial value of the "name" attribute of the above model without doing another query.

php laravel

Laravel saves the original attributes of the model within the original property.

$user = User::first();

$user->name = 'Rafael';

dd(
    $user->getAttributes(), // contém o atributo nome novo.
    $user->getOriginal() // contém o atributo nome antigo.
);

If you want to access a specific attribute of the original values, simply pass its name by parameter of Model::getOriginal .

Example:

  $user->getOriginal('name');

You can check directly in the api, in this link .
