DateTimer with custom format throws an exception

[plamenradev]

Describe the bug DateTimer with custom format throws exception if any other field is filled incorrect.

To Reproduce

1. Create form layout with DateTimer (lets say for date of birth - DOB) and at least one more other type field, for example simple Input for email.
2. Set format and serverFormat on the DateTimer, for example "d/m/Y"
3. Create validation rules - for DateTimer: "date_format:d/m/Y", for the other Input field - for example "unique:users,email"
4. Fill the form with any date in the DateTimer and email, which is already taken by another user.
5. After submit it throws an InvalidFormatException: Could not parse '22/03/2023': Failed to parse time string (22/03/2023) at position 0 (2): Unexpected character
6. If the email validation is OK - there is no InvalidFormatException and everything is working fine.

Layout:

class UserEditLayout extends Rows
{
    public function fields(): array
    {
        return [
            Input::make('user.email')
                ->type('email')
                ->title(__('Email Address')),

            DateTimer::make('user.dob')
                ->title('Date of Birth')
                ->allowInput()
                ->serverFormat(config('app.date_format')) // Set to d/m/Y
                ->format(config('app.date_format')) // Set to d/m/Y
                ->help(__('Format DD/MM/YYYY')),
        ];
    }
}

Screen save method:

public function save(User $user, UserRequest $request)
{
    $request->validate($request->rules());
    $user->when($request->filled('user.password'), function (Builder $builder) use ($request) {
        $builder->getModel()->password = Hash::make($request->input('user.password'));
    });

    $user
        ->fill(collect($request->validated('user'))->except('password')->all())
        ->save();

    Toast::info(__('User saved'));
}

UserRequest class:

class UserRequest extends FormRequest
{
    public function rules()
    {
        $ignoreId = $this->route('user') ? ',' . $this->route('user')->id : '';

        return [
            'user.email' => 'email|nullable|unique:users,email' . $ignoreId,
            'user.dob' => 'date_format:' . config('app.date_format') . '|nullable', // Set to d/m/Y
        ];
    }

    public function validated($key = null, $default = null)
    {
        $validated = data_get($this->validator->validated(), $key, $default);
        $merged = collect($validated);

        if ($merged->get('dob')) {
            $merged->put('dob', Carbon::createFromFormat(config('app.date_format'), $merged->get('dob'))->format('Y-m-d'));
        }

        return $merged->all();
    }
}

Expected behavior Correct parsing the date

Server (please complete the following information):

• Platfrom Version: 13.8.0
• Laravel Version: 9.42.
• PHP Version: 8.1.9
• Database: MySql
• Database Version: 8.0.30

Additional context The date_of_birth fields in the database has type date I tried to play with prepareForValidation() and failedValidation() methods in the UserRequest class, but it still throws an exception.

When you use a custom format for DateTimer and it throws an validation exception - you need to return back the date value in such a format, that could be parsed by Carbon::parse(), so here is an ugly solution, but it works, just for letting you know the idea.

In UserRequest class overwrite the following function:

protected function failedValidation(Validator $validator): void
{
}

In Screen save method:

public function save(User $user, UserRequest $request)
{
    $validator = Validator::make($request->input(), $request->rules());

    if ($validator->fails()) {
        $input = $request->input();
        data_set($input, 'user.dob', Carbon::createFromFormat(config('app.date_format'), $request->input('user.dob'))->format('Y-m-d'));

        return redirect(url()->previous())
            ->withInput($input)
            ->withErrors($validator->errors()->messages());
    }

    ...
}
