UUID in Laravel: All You Need To Know

Hello Povilas,

In the article you say:

Then, the new Laravel 9.30 way doesn't apply because it works only for primary keys

But in the Laravel documentation it says:

In addition, you may specify which columns should receive UUIDs by defining a uniqueIds method on the model

/**
 * Get the columns that should receive a unique identifier.
 *
 * @return array
 */
public function uniqueIds()
{
    return ['id', 'discount_code'];
}

Source: https://laravel.com/docs/9.x/eloquent#uuid-and-ulid-keys

So can't we use this method to use secondary UUID without making primary key?

Thanks for the detailed information with example. It will be useful for larger projects to use.

shouldn't app/Traits/Uuid.php contain bootUuid insead of just boot with the removal of parent::boot(); ? because it might result in boot method collision

The approach that works with both an id and a uuid seems best to me, but if you specify in the getRouteKeyName a uuid, does that mean if you have a relationship (eg belongs_to) laravel is going to try too use the uuid to find/store the relationship?

Or will it still use the id then? that last option would be perfect because you would retain the speed and simplicity in for example pivot tables.

Edit: ok that's perfect I tested it and (of course, should learn to read better) getRouteKeyName only involves the route, in Filament everything immediatly works perfectly when setting this.
