Generate Filament Resource from Existing DB Schema

You can generate Filament Resource with "--generate". It will try to guess the fields from your DB schema!

php artisan make:filament-resource Model --generate

My example is with a Category model with a "name" field.

php artisan make:filament-resource Category --generate

class CategoryResource extends Resource
{
    // ...
 
    public static function form(Form $form): Form
    {
        return $form
            ->schema([
                Forms\Components\TextInput::make('name')
                    ->required()
                    ->maxLength(255),
            ]);
    }
 
    // ...
}

Notice: this auto-generation would not be always accurate, so make sure to double-check the result and make the necessary changes. Also, it would not work if you have Enum columns in your DB table.
