@naykel not sure I understand you correctly... Laravel offers https://laravel.com/docs/8.x/validation#rule-date and https://laravel.com/docs/8.x/validation#rule-date-format to validate input dates. Did you try that?

Livewire date casting and validation problem
I am trying to implement date validation on a livewire component, and it appears that date casting happens before validation resulting with errors.
After days of googling, I have tried so many things I am at a loss, but from what I have figured out this is only a problem when using nested properties.The common pattern I have found is:
In the model
protected $casts = [
'expires_at' => 'date',
];
protected $appends = ['expiry_date_for_editing'];
public function getExpiryDateForEditingAttribute()
{
return $this->expires_at->format('d/m/y');
}
public function setExpiryDateForEditingAttribute($value)
{
dd('why is firing before validation takes place?????');
$this->expires_at = Carbon::createFromFormat('d/m/y', $value)->format('Y-m-d');
}
In the livewire component validation rules I have
protected $rules = [
'editing.expiry_date_for_editing' => 'required',
];
I am aware that there is no date formatting in the validation rules above but I can't even get the required rule to fire. To test I deleted the date and tried to save save it just throws and error saying data missing.

I tried working with the rules as you have linked to but I think the problem exists because the mutator is firing before the validator so it does not get the chance to do it's job.
In the example I have above you will see that the only validation I have is required so you would expect a validation error when you submit an empty field but this is not the case, the error thrown is a carbon error.
Hope this makes it a little cleared.

@naykel hi! Its a year old post but..... did you find a solution? I have exact the same problem. Mutator fired before the rules check Thanks

@limeframe from memory I did not find a solution to this exact problem. I ended up created a date cast with the expectation that the date picker will always supply the correct format. I am sure future me will not like this but as it was only a small scale app and I was fed up trying to solve the problem so I just threw a band aid on.
// livewire validation
protected $rules = [
'editing.expired_at' => 'sometimes|date',
];
// custom cast
use Illuminate\Contracts\Database\Eloquent\CastsAttributes;
class DateCast implements CastsAttributes {
public function get($model, $key, $value, $attributes)
{
return $value ? Carbon::createFromFormat('Y-m-d H:i:s', $value)->format('d-m-Y') : null;
}
public function set($model, $key, $value, $attributes)
{
return $value ? Carbon::parse($value) : null;
}
}
}
