Filament form with factory data

Sometimes, when we need to test our application locally, we always have to fill forms manually. Let's take the Filament approach and achieve this with more accurate data.

Prepare the Factory definition

 1class PostFactory extends Factory
 2{
 3    public function definition(): array
 4    {
 5        $title = $this->faker->sentence;
 6 
 7        return [
 8            'title' => $title,
 9            'slug' => str($title)->slug()->toString(),
10            'excerpt' => $this->faker->sentences(3, true),
11            'body' => $this->faker->sentences(10, true),
12        ];
13    }
14}

Fill the Form Action

 1<?php
 2 
 3namespace App\Filament\Resources\PostResource\Pages;
 4 
 5use App\Filament\Resources\PostResource;
 6use App\Models\Post;
 7use Filament\Actions\Action;
 8use Filament\Resources\Pages\CreateRecord;
 9 
10class CreatePost extends CreateRecord
11{
12    protected static string $resource = PostResource::class;
13 
14    protected function getHeaderActions(): array
15    {
16        return [
17            Action::make('form-fake-filler')
18                ->label('Fill Form')
19                ->icon('heroicon-o-sparkles')
20                ->color('info')
21                ->action(function(self $livewire): void {
22                    $data = Post::factory()->make()->toArray();
23 
24                    $livewire->form->fill($data);
25                }),
26        ];
27    }
28}

Let's show this button only when we are in development mode. To achieve this, let's add a condition to our action definition:

 1//...
 2protected function getHeaderActions(): array
 3{
 4    return [
 5        Action::make('form-fake-filler')
 6            //...
 7            ->action(function(self $livewire): void {
 8                $data = Post::factory()->make()->toArray();
 9 
10                $livewire->form->fill($data);
11            })
12            ->visible(fn () => app()->environment('local'))
13    ];
14}
15//...
