Laravel Nova Detached Actions Tool

A Laravel Nova tool to allow for placing actions in the Nova toolbar, detached from the checkbox selection mechanism.

The action is detached from the row selection checkboxes in the resource table, so you will not have a collection of models to iterate over. Detached actions are intended to be independent of the selection in the table.

This is a fork of gobrightspot/nova-detached-actions abandoned repo, i rewrite a lot of part in using vue 3 composition api.

⚠️ Pivot actions are not supported and have not been tested.

Mobile compatibility

Installation

You can install the package in to a Laravel app that uses Nova via composer:

composer require datomatic/nova-detached-actions

The tool will be automatically registered via the ToolServiceProvider

Usage

Create a custom Nova Action file:

php artisan nova:action ExportUsers

Instead of extending the ExportUsers class with the Laravel\Nova\Actions\Action class, swap it with the Datomatic\Nova\Tools\DetachedActions\DetachedAction class.

Since we won't receive a collection of $models, you can remove the variable from the handle method, so that the signature is public function handle(ActionFields $fields).

After registration the detached action will appear on the Index Toolbar.

Here's a full example:

<?php

namespace App\Nova\Actions;

use Datomatic\Nova\Tools\DetachedActions\DetachedAction;
use Illuminate\Bus\Queueable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
use Laravel\Nova\Fields\ActionFields;

class ExportUsers extends DetachedAction
{
    use InteractsWithQueue, Queueable, SerializesModels;
    
    public function name(): string
    {
        return __('Export Users');
    }

    /**
     * Perform the action.
     *
     * @param  ActionFields  $fields
     *
     * @return mixed
     */
    public function handle(ActionFields $fields)
    {
        // Do work to export records

        return DetachedAction::message('It worked!');
    }

    /**
     * Get the fields available on the action.
     *
     * @return array
     */
    public function fields()
    {
        return [];
    }
}

Register the action on your resource:

/**
 * Get the actions available for the resource.
 *
 * @param  \Laravel\Nova\Http\Requests\NovaRequest  $request
 * @return array
 */
public function actions(NovaRequest $request)
{
    return [
        new App\Nova\Actions\ExportUsers // or App\Nova\Actions\ExportUsers::make() 
    ];
}

Customizing Buttons

Visible vs Invisible Buttons

By default, the component will show the first 3 buttons and put the rest into a dropdown menu. In the dropdown menu you can't add icon or extra classes because it use the nova dropdown component. If you want to change the number of buttons visible per resource, you can do so by using the additionalInformation method in the resource class, like so:

public static function additionalInformation(Request $request)
{
    return [
        'visibleActionsLimit' => 2
    ];
}

Customizing Button Classes

The package ships with some common sense default HTML classes that are applied to the action buttons. In the component, we automatically assign the following:

hover:bg-gray-200 dark:hover:bg-gray-900 flex-shrink-0 rounded focus:outline-none focus:ring inline-flex items-center font-bold px-3 h-9 text-sm flex-shrink-0

A developer can add classes on the fly, using the extraClasses() method on the DetachedAction class.

The extraClasses() method

You are free to use any tailwind/nova class.

return [
   (new ImportUsers)->extraClasses('bg-primary-500 text-white hover:black')
];

The $defaultClasses variable

You can also extend DetachedAction class and change the default classes on $defaultClasses variable.

For example, you can add the classes to be equal to nova primary button

shadow ring-primary-200 dark:ring-gray-600 bg-primary-500 hover:bg-primary-400 dark:hover:bg-primary-400 active:bg-primary-600 text-white dark:text-gray-800

Adding an icon

You can use any of the 104 Heroicon icons by specifying the icon name in lowercase:

return [
   (new ImportUsers)->icon('add')
];

You can also customize the display of that icon using iconClasses:

return [
   (new ImportUsers)->icon('upload')->iconClasses('mr-3 -ml-2')
];

Chunking and repetitive calls to the handle()

If you initiate an action on the background Nova will chunk up the total amount of records and call the handle() function of your DetachedAction for each chunk. This could have unexpected performance impact as the system will perform your action for each chunk of records. This happens in the handleRequest() function of \Laravel\Nova\Actions\Action.php.

To prevent this the simplest way is to overrule this function in your DetachedAction. this is a bare example dispatching just a job without any checks or other logic:

/** @return array<int,string> */
public function handleRequest(ActionRequest $request): array
{
    dispatch(new GenerateTicketReport($request->resolveFields()));
    return DetachedAction::message('Nice job!');
}
