Form

Validation

Validation is as easy as in the FormRequests classes from Laravel.

It is enough to add rules in the model resource rules() method in the usual manner.

namespace App\MoonShine\Resources;
 
use App\Models\Post;
use MoonShine\Fields\Text;
use MoonShine\Resources\ModelResource;
 
class PostResource extends ModelResource
{
    protected string $model = Post::class;
 
    protected string $title = 'Posts';
 
    //...
 
    public function rules($item): array
    {
        return [
            'title' => ['required', 'string', 'min:5']
        ];
    }
 
    //...
}

Messages

Using the validationMessages() method you can create your own validation error messages.

namespace App\MoonShine\Resources;
 
use App\Models\Post;
use MoonShine\Fields\Text;
use MoonShine\Resources\ModelResource;
 
class PostResource extends ModelResource
{
    protected string $model = Post::class;
 
    protected string $title = 'Posts';
 
    //...
 
    public function validationMessages(): array
    {
        return [
            'email.required' => 'Required email'
        ];
    }
 
    //...
}

Preparing input data for verification

If you need to prepare or clean up any data from the request before applying your validation rules, you can use the prepareForValidation() method.

namespace App\MoonShine\Resources;
 
use App\Models\Post;
use MoonShine\Fields\Text;
use MoonShine\Resources\ModelResource;
 
class PostResource extends ModelResource
{
    protected string $model = Post::class;
 
    protected string $title = 'Posts';
 
    //...
 
    public function prepareForValidation(): void
    {
        moonshineRequest()?->merge([
            'email' => request()
                ?->string('email')
                ->lower()
                ->value()
        ]);
    }
 
    //...
}

Buttons

To add buttons, use ActionButton and the FormButtons or buttons methods in the resource.

More details ActionButton

public function formButtons(): array
{
    return [
        ActionButton::make('Link', '/endpoint'),
    ];
}

You can also use the buttons method, but in this case, the buttons will be on the resource all other pages.

public function buttons(): array
{
    return [
        ActionButton::make('Link', '/endpoint'),
    ];
}

Asynchronous mode

Switch mode without reboot to save data.

namespace App\MoonShine\Resources;
 
use App\Models\Post;
use MoonShine\Resources\ModelResource;
 
class PostResource extends ModelResource
{
    protected string $model = Post::class;
 
    protected string $title = 'Posts';
 
    protected bool $isAsync = true;
 
    // ...
}

Switch form mode to Precognitive validation.

namespace App\MoonShine\Resources;
 
use App\Models\Post;
use MoonShine\Resources\ModelResource;
 
class PostResource extends ModelResource
{
    protected string $model = Post::class;
 
    protected string $title = 'Posts';
 
    protected bool $isPrecognitive = true;
 
    // ...
}
