Casting properties types

#1

What seems to be the problem:
What types for casting properties are supported?
I am sure they are not the same as Laravel?

Are you using the latest version of Livewire:
Yes, sir!

Do you have any screenshots or code examples:

use Livewire\Component;

class Example extends Component
{
    public $persons;

    protected $casts = [
        'persons' => 'integer',
    ];
}

Result:

ErrorException
Casting to type [integer] not supported.

Illuminate\View\Engines\CompilerEngine::handleViewException
vendor/livewire/livewire/src/DataCaster.php:40

...

protected function ensureTypeExists($type)
{
    $isSupported = isset($this->casters[$type]) || class_exists($type);
 
    throw_unless(

        $isSupported,

====>   new \Exception("Casting to type [{$type}] not supported.")

    );

}

What types are currently supported?

EDIT:
In the source code, I see this the only ones that are supported is the date and collection types.

On the website is says the following:

Two common use-cases for this are working with date objects like Carbon instances, and dealing with Laravel collections

Not common use-cases, but the only use-cases :wink:

Kind regards,
Edwin

It’s super simple to make your own

class IntegerCaster implements Castable
{
    public function cast($value)
    {
        return (int) $value;
    }

    public function uncast($value)
    {
        return $value;
    }
}
