Problem description

Issue

When using an enum that is backed by int and used in a table, there is code in select-column.blade.php that tries to stringify the enum value, but int enums do not support __toString() unfortunately, so we might need to check explicitly for this case and manually convert the enum's value to string.

See code below, exception fires when visiting: admin/users

Exception

Object of class App\Enums\UserProviderType could not be converted to string

Code

UserProviderType.php:

namespace App\Enums;

use Filament\Support\Contracts\HasLabel;

enum UserProviderType: int implements HasLabel
{
    case APPLE = 1;
    case GOOGLE = 2;

    public function getLabel(): ?string
    {
        return match($this) {
            self::APPLE => 'Apple',
            self::GOOGLE => 'Google'
        };
    }
}

UserResource.php:

 public static function table(Table $table): Table
    {
        return $table
            ->columns([
                Tables\Columns\SelectColumn::make('provider_type')
                                    ->label('Provider')
                                    ->options(UserProviderType::class)
                                    ->sortable(),
            ]);
}

`User.php:

protected $casts = [
        'email_verified_at' => 'datetime',
        'provider_type' => UserProviderType::class,
    ];

select-column.blade.php:

<input
        type="hidden"
        value="{{ str($state)->replace('"', '\\"') }}"
        x-ref="newState"
    />

Expected behavior

Since int backed enums can easily be translated to string, we can use reflection or other mechanism to detect and provide the string value?

select-column.blade.php

@php
    $canSelectPlaceholder = $canSelectPlaceholder();
    $isDisabled = $isDisabled();
    $rawState = $getState();

    try {
        $state = str($rawState);
    } catch (\Throwable $e) {
        $reflectedEnum = new ReflectionEnum($rawState);
        $reflectedBackingType = $reflectedEnum->getBackingType();

        if ($reflectedBackingType === 'int') {
            $state = str($rawState->getValue());
        } else {
           // re-throw
        }
    }
@endphp

Oddly enough, it works on the edit page, just not on the select column in the table. The enum is hooked up roughly the same way, but it's the Select component, not the SelectColumn:

Select::make('provider_type')
                    ->label('Provider')
                    ->options(UserProviderType::class)
                    ->searchable(),

So maybe bringing some code over from Select into SelectColumn :)

Steps to reproduce

1. Create int backed enum
2. Hook up to form table select as direct class usage
3. Visit url to invoke table render
4. Exception fires

See the last commit of my repro for the more important pieces, the first 2 commits were just Laravel install, then Filament install:

Would appreciate a PR to fix this if you can

Will do sometime this week, if not next week :) thanks Dan!

Opened up https://github.com/filamentphp/filament/pull/7962 but would love some eyes on it @danharrin! :)

I am having a similar problem using a string type enumerator.

<?php

namespace App\Enums;

use Filament\Support\Contracts\HasLabel;

enum WaitlistStatus: string implements HasLabel
{
  case WAITING = 'waiting';
  case CALLED = 'called';

  public function getLabel(): ?string
  {
    return match ($this) {
      self::WAITING => 'Na fila',
      self::CALLED => 'Chamado',
    };
  }
}

@php
    $canSelectPlaceholder = $canSelectPlaceholder();
    $isDisabled = $isDisabled();
    $state = $getState();
    dd($state);
@endphp

App\Enums\WaitlistStatus {#3167 ▼ // vendor/filament/tables/src/../resources/views/columns/select-column.blade.php
  +name: "WAITING"
  +value: "waiting"
}

Returns the error: Object of class App\Enums\WaitlistStatus could not be converted to string

Making this change works... but obviously, the solution must be more complex.
