A tags field for Nova apps that uses cartalyst/tags

A tags field for Nova apps

This package contains a Nova field to add tags to resources. Under the hood it uses the cartalyst/tags package.

This package is based on spatie/nova-tags-field. All credit to Spatie's team.

Installation

First you must install cartalyst/tags into your Laravel app. Here are the installation instructions for that package.

Next, you can install this package in to a Laravel app that uses Nova via composer:

composer require palauaandsons/nova-tags-field

Usage

To make an Eloquent model taggagle add the \Cartalyst\Tags\TaggableTrait trait and implement the \Cartalyst\Tags\TaggableInterface interface:

use Cartalyst\Tags\TaggableTrait;
use Cartalyst\Tags\TaggableInterface;
use Illuminate\Database\Eloquent\Model;

class BlogPost extends Model implements TaggableInterface
{
    use TaggableTrait;
    
    ...
}

Next you can use the PalauaAndSons\TagsField\Tags field in your Nova resource:

namespace App\Nova;

use PalauaAndSons\TagsField\Tags;

class BlogPost extends Resource
{
    // ...
    
    public function fields(Request $request)
    {
        return [
            // ...
            
            Tags::make('Tags'),

            // ...
        ];
    }
}

Now you can view and add tags on the blog posts screen in your Nova app.

Limiting suggestions

By default a tags field will display a maximum of 5 suggestions when typing into it. If you don't want to display any suggestions, tag on withoutSuggestions().

Tags::make('Tags')->withoutSuggestions(),

You can change the number of suggestions with limitSuggestions().

Tags::make('Tags')->limitSuggestions($maxNumberOfSuggestions),

Allowing only one tag

If the user is only allowed to select one tag for your resource you can call the single method.

// in your Nova resource

public function fields(Request $request)
{
    return [
        // ...
        
        Tags::make('Tags')->single(),

        // ...
    ];
}

The field will be rendered as a select form element. It will be populated by the names of the tags already saved.

Working with tags

For more info on how to work with the saved tags, head over to the docs of cartalyst/tags.

Administering tags in Nova

If you want to perform crud actions on the save tags, just create a Nova resource for it. Here's an example.

namespace App\Nova;

use Illuminate\Http\Request;
use Laravel\Nova\Fields\Text;
use Cartalyst\Tags\IlluminateTag as TagModel;

class Tag extends Resource
{
    public static $model = TagModel::class;

    public static $title = 'name';

    public static $search = [
        'name',
    ];

    public function fields(Request $request)
    {
        return [
            Text::make('Namespace')->sortable()->hideWhenUpdating(),
            Text::make('Name')->sortable(),
            Text::make('Slug')->sortable(),
        ];
    }
}
