Fill Form Field Value with Suggestion from OpenAI API

We have a simple form with a Multi-Select for Tags:

app/Filament/Resources/JobOfferResource.php

<?php
 
namespace App\Filament\Resources;
 
use App\Filament\Resources\JobOfferResource\Pages;
use App\Filament\Resources\JobOfferResource\RelationManagers;
use App\Models\JobOffer;
use App\Models\Tag;
use App\Services\OpenAiService;
use Filament\Forms;
use Filament\Forms\Form;
use Filament\Resources\Resource;
use Filament\Tables;
use Filament\Tables\Table;
 
class JobOfferResource extends Resource
{
    protected static ?string $model = JobOffer::class;
 
    protected static ?string $navigationIcon = 'heroicon-o-rectangle-stack';
 
    public static function form(Form $form): Form
    {
        return $form
            ->schema([
                Forms\Components\TextInput::make('title')
                    ->required(),
                Forms\Components\Select::make('source_id')
                    ->relationship('source', 'name')
                    ->required(),
                Forms\Components\Textarea::make('description')
                    ->required()
                    ->rows(10)
                    ->columnSpanFull(),
                Forms\Components\Select::make('tags')
                    ->columnSpan(2)
                    ->relationship('tags', 'name')
                    ->createOptionForm([
                        Forms\Components\TextInput::make('name')
                    ])
                    ->createOptionUsing(function (array $data): int {
                        return Tag::create($data)->id;
                    })
                    ->multiple(),
            ]);
    }
 
    // ...
}

And here we want to add a OpenAI query to extract these tags automatically using AI. So let's create our Action button:

app/Filament/Resources/JobOfferResource.php

// ...
 
Forms\Components\Textarea::make('description')
    ->required()
    ->rows(10)
    ->columnSpanFull(),
Forms\Components\Actions::make([
    Forms\Components\Actions\Action::make('extractTags')
        ->action(function (Forms\Get $get, Forms\Set $set) {
            $tags = (new OpenAiService())->retrieveTagsForDescription($get('description'));
            // ...

Next we will create:

• OpenAiService that calls OpenAI API
• Prompts
• Automatic selection of new suggested tags
