TypeError on resource where column is an Enum

I have a User Model, and did like this: php artisan make:filament-resource UserResource -G
and when I try to view the users i get this:

Filament\Tables\Columns\TextColumn::Filament\Tables\Columns\Concerns\{closure}(): Return value must be of type ?string, App\Enums\UserLevelEnum returned

Filament\Tables\Columns\TextColumn::Filament\Tables\Columns\Concerns\{closure}(): Return value must be of type ?string, App\Enums\UserLevelEnum returned

I get it even if I remove the column that uses enum the enum:

enum UserLevelEnum: int implements HasLabel
{
---
}

enum UserLevelEnum: int implements HasLabel
{
---
}

What am I missing ?

Solution:

Why do you have numeric method on the TextColumn?

Do you have any casts defined on the User Model?

    protected function casts(): array
    {
        return [
            'email_verified_at' => 'datetime',
            'password' => 'hashed',
            'user_level' => UserLevelEnum::class,
        ];
    }

    protected function casts(): array
    {
        return [
            'email_verified_at' => 'datetime',
            'password' => 'hashed',
            'user_level' => UserLevelEnum::class,
        ];
    }

can you add the code of the enum class also here. If you use HasLabel on the enum, the text column should automatically use it. https://filamentphp.com/docs/3.x/support/enums#using-the-enum-label-with-a-text-column-in-your-table

<?php

namespace App\Enums;

use App\Enums\Traits\EnumHelper;
use Filament\Support\Contracts\HasLabel;

enum UserLevelEnum: int implements HasLabel
{
    use EnumHelper;

    case None = 0;
    case Free = 1;
    case Standard = 10;
    case Plus = 20;
    case Pro = 30;
    case Special = 40;
    case Admin = 90;
    case Unlimited = 999;

    public function getLabel(): ?string
    {
        return match ($this) {
            self::None => ('None'),
            self::Free => ('Free'),
            self::Standard => ('Standard'),
            self::Plus => ('Plus'),
            self::Pro => ('Pro'),

            self::Admin => ('Admin'),

Looks fine. OK, can you send me the TextColumn code on the resource that binds the user_level

rabolOP•7mo ago

Tables\Columns\TextColumn::make('user_level') ->numeric() ->sortable(),

Abi•7mo ago

not sure what the EnumHelper does, can you try removing that trait to see if that fixes.

Why do you have numeric method on the TextColumn?

Abi•7mo ago

can you remove that

rabolOP•7mo ago

-G the make command made it like this

Abi•7mo ago

did you generate the code before casting the column to UserLevel Enum? If so, the make command would use the type of the column on the DB to set that method. Remove that since you have a cast on the modal and that should do it

rabolOP•7mo ago

no, code was created after - I'm trying to switch from Nova to Filament on this I just did a php artisan make:filament-resource UserResource -G --force and this is the outcome Tables\Columns\TextColumn::make('user_level') ->numeric() ->sortable(), so maybe a bug @Dan Harrin 🙂

Dan Harrin•7mo ago

please open an issue with reproduction

Abi•7mo ago

din't removing the ->numeric() method no help?

rabolOP•7mo ago

yes, that helped but the 'bug' is that this is generated

Tables\Columns\TextColumn::make('user_level')
                    ->numeric()
                    ->sortable(),

Tables\Columns\TextColumn::make('user_level')
                    ->numeric()
                    ->sortable(),

by the command

php artisan make:filament-resource UserResource -G

php artisan make:filament-resource UserResource -G
