How to change date format in Laravel model?

Question

Laravel

The Laravel documentation says about the model property $dateFormat that this property determines how date attributes are stored in the database.
I use this property like this because I want only the date to be stored, not the time. But as a result, working with the date becomes impossible, i.e. even with a simple output it gives an errorprotected $dateFormat = 'Y-m-d'$model->created_at

Trailing data {"exception":"[object] (InvalidArgumentException(code: 0): Trailing data at ...\www\\vendor\
esbot\\carbon\\src\\Carbon\\Carbon.php:910)...

Those. the date of such a model is no longer perceived as a Carbon object, but, apparently, as a string, and any manipulations with the date as a date are no longer possible. Right?
Who can tell where to read about this, and how to change the date format in which the date is written to the database, while leaving it in the Carbon format?

Answer 1

Question: why change the date entered into the database, if it is enough to change its presentation in appearance?
There is such an option - add to the model

protected $casts = [
    'created_at' => 'datetime:d/m/Y', // Свой формат
    'updated_at' => 'datetime:d/m/Y',
];

Well, read this chapter of the documentation
