Actions

A resource may have custom actions. Actions are pieces of code that can be executed in bulk (from the index page), or from the detail page.

By default, every resource includes a DeleteResource action:

(new DeleteResource())
    ->canRun(fn (Model $model) => auth()->user()->can('delete', $model))
    ->rejectReason(function () {
        return __("You don't have permission to delete this");
    })

Creation an action

Let's start by creating a BlockUser action:

class BlockUser extends Action
{
    public function icon(): string
    {
        return 'block';
    }
       
    public function title(): string
    {
        return __('Block user');
    }
       
    public function run(Model $model, array $state): void
    {
        $model->blocked = true;
        $model->save();
        logout($model);
    }
}

The run action will be called for every model that is selected (via bulk).

Registering an action

You can register an action on the resource:

public function actions(): ActionCollection
{
    return new ActionCollection(
        new BlockUser()
    };
}

Authorization and rejection

Visibility

You can hide actions on detail or on index using:

public function actions(): ActionCollection
{
    return new ActionCollection(
        (new BlockUser())
            ->hideOnIndex()
    };
}

Authorization

Actions will can only be executed when users are authorized to see and run the action. To check whether an action can be seen:

public function actions(): ActionCollection
{
    return new ActionCollection(
        (new BlockUser())
            ->canSee(function() {
                return auth()->user()->hasPermissionTo('update users');
            })
    };
}

And to check if it can be run:

public function actions(): ActionCollection
{
   return new ActionCollection(
       (new BlockUser())
           ->canRun(fn(UserModel $model) => !$model->blocked)
   };
}

Rejection

When, for example in bulk, an action cannot be run for a specific model, you can also supply a reject reason:

public function actions(): ActionCollection
{
   return new ActionCollection(
       (new BlockUser())
           ->canRun(fn(UserModel $model) => !$model->blocked)
           ->rejectReason(function () {
               return __('This user is already blocked');
           })
   };
}

Including fields

You can include fields in your actions. For example you might want to fill in a block_reason when blocking an user:

class BlockUser extends Action {
    //...
    
    public function fields(): FieldCollection
    {
        return new FieldCollection(
            Text::make(__('Block reason'), 'block_reason')
                ->rules('nullable', 'string', 'max:255')
        );
    }
    
    public function run(Model $model, array $state): void
    {
        $model->block_reason = $state['block_reason'];
    }
    
    //...
}

Redirecting

Sometimes, you may want to redirect the user to the index page after executing an action. For example after deleting the resource:

public bool $shouldRedirectToIndex = true;

You can also have a custom redirect url by adding the following method on your Action. This will only be used from the detail page.

public function redirectTo(Collection $models, array $arguments): ?string
{
    return 'https://google.com';
}

You can redirect to a specific model detail page:

public function redirectTo(Collection $models, array $arguments): ?string
{
    return "resources/tickets/{$this->model->id}";
}

Downloading files

It is also possible to return a file response when an action is finished.

In order to make this work, you will need to add the following function, which should return the full path to the file:

public function downloadableFilePath(): ?string
{
    return Storage::disk('public_global')->path('avatars/users/1.png');
}

warning

You should not generate a file inside downloadableFilePath function, because it is called multiple times. Instead, you should generate a file in the run function (or somewhere else), and store the path as a property on the class, which you then can return in the downloadableFilePath function.

By default, downloaded files are opened in a new browser tab. You can disable this:

public function openFileInTab(): bool
{
    return false;
}

info

After changing anything file related, make sure to refresh the page once

If for some reason you need to send a custom response (with custom headers), you can override the following function:

public function onFinished(Collection $models, array $arguments): mixed
{
    return response()->[...]
}

Action metadata

By default, an action description is the same as the title. You can supply your own description:

public function description(): string
{
    return __('I am the description for this action');
}

You can set a width for the dialog/modal that is shown (default is 700):

public int $width = 1000;

You can change the labels of submit and cancel buttons:

public function submitLabel(): string
{
    return __('Save');
}

public function cancelLabel(): string
{
    return __('Cancel');
}

You can hide the submit button by default:

public function showSubmitButton(): bool
{
    return $this->model->is_active;
}

You can mark the submit button as disabled by default:

public function disableSubmitButton(): bool
{
    return true;
}

public function disableSubmitButtonMessage(): ?string
{
    return __('Disabled message');
}

To apply a front-end indicator that the action might be "dangerous", you can use the following property:

public bool $dangerous = true;

You can set widths:

public int $width = 700; // Pixels
public int $maxWidth = 80; // VW

You can set a custom response message:

protected function responseMessage(Collection $models, array $arguments): string
{
    return __('Action :action ran successfully', [
        'action' => $this->description()
    ]);
}

If you'd like to modify the form in some other way, you can override the following method:

public function onFormReady(ManagesForm $form): void
{
    // On subsequent requests we do nothing
    if (!$form->isInitialRequest()) {
        return;
    }

    // Hide the submit button by default
    if (!$this->showSubmitButton()) {
        $form->hideSubmitButton();
    }

    // Disable the submit button by default
    if ($this->disableSubmitButton()) {
        $form->disableSubmitButton($this->disableSubmitButtonMessage());
    }
}

Overriding components

You can override the front-end with the following 2 methods:

    public function headerComponent(): string
    {
        return 'CustomActionHeader';
    }

    public function bodyComponent(): string
    {
        return 'CustomActionBody';
    }

Then in the front-end:

import CustomActionBody from '../CustomActionBody'
import CustomActionHeader from '../CustomActionHeader'

Vue.component('CustomActionBody', CustomActionBody)
Vue.component('CustomActionHeader', CustomActionHeader)

CustomActionHeader:

  <q-card-section>
    <div class="text-h6">
      <q-avatar

        :color="action.dangerous ? 'negative' : 'primary'"
        text-color="contrast"
      />
      {{ action.title }}
    </div>
    <div
      class="text-subtitle2"
