How to get related Model id in Laravel factory - php

Question

I am trying to save the image using faker in the storage folder. I want to keep the images inside the property ID folder. I have tried the below code but it is not working. It hangs the command prompt. The properties have multiple images and are a one-to-many relation. The code below is for the PropertyImageFactory class.
public function definition()
{
$property_id = $this->create(Property::class)->id;
return [
'name' => $this->faker->image(storage_path('app/property-images/'.$property_id), 200, 200, 'cats'),
'sort_order' => $this->faker->numberBetween(1, 10),
'created_at' => now(),
'updated_at' => now(),
];
}
Laravel documentation has 'user_id' => User::factory(), I can't use this because it returns an object and I can't concatenate to string.
Below is the code for the property seeder.
public function run()
{
Property::factory()
->has(Category::factory()->count(3))
->has(PropertyImage::factory()->count(3), 'images')
->count(5)
->create();
}

Yup, that will return a UserFactory object just as Property::factory() will return a PropertyFactory. What you want to do is call the create() method on the factory and get the id from the record that is created.
$proprty_id = (\App\Models\Property::factory()->create())->id;

Laravel extracts the ID from the SomeModel::factory(), that's all the magic of Laravel. To do this, you need to properly describe the SomeModelFatory. You can use: $property_id = Property::factory();
As far as I know faker->image no longer works, I can advise using an auxiliary class for image formation.
<?php
namespace App\Helpers;
use Faker\Factory;
use Illuminate\Support\Facades\File;
class Image
{
public static function imageUrl(
int $width = 640,
int $height = 480,
bool $randomizeColors = false,
bool $randomizeTxt = false,
string $format = 'jpg'
): string
{
$baseUrl = "https://dummyimage.com";
$size = "/{$width}x{$height}";
$colors = "/aaa/fff";
$format = '.' . preg_replace('~^\b(?:jpg|png|gif)$~', 'jpg', $format);
if ($randomizeColors) {
$backgroundColor = str_replace('#', '', Factory::create()->safeHexColor);
$foreColor = str_replace('#', '', Factory::create()->safeHexColor);
$colors = "/{$backgroundColor}/{$foreColor}";
}
return $baseUrl . $size . $colors . $format . ($randomizeTxt ? '&text=' . Factory::create()->word : '');
}
public static function fake(
string $dir = null,
int $width = 640,
int $height = 480,
bool $randomizeColors = false,
bool $randomizeTxt = false,
string $format = 'jpg',
bool $fullPath = false
)
{
$dir = is_null($dir) ? sys_get_temp_dir() : $dir;
if (!is_dir($dir) || !is_writable($dir)) {
throw new \InvalidArgumentException("Unable to write to directory $dir");
}
$name = md5(uniqid(empty($_SERVER['SERVER_ADDR']) ? '' : $_SERVER['SERVER_ADDR'], true));
$filename = $name . ".$format";
$filepath = $dir . DIRECTORY_SEPARATOR . $filename;
$url = static::imageUrl($width, $height, $randomizeColors, $randomizeTxt, $format);
try {
$image = file_get_contents($url, false, stream_context_create(['http' => ['timeout' => 10]]));
try {
if (!File::put($filepath, $image)) {
return false;
}
} catch (\Exception $e) {
throw new \Exception($e->getMessage());
}
} catch (\Exception $e) {
throw new \Exception($e->getMessage());
}
return $fullPath ? $filepath : $filename;
}
}
and use:
public function definition()
{
$property_id = Property::factory();
$dir = storage_path('app' . DIRECTORY_SEPARATOR . 'public' . DIRECTORY_SEPARATOR . $property_id);
mkdir($dir, 755);
return [
'name' => (\App\Helpers\Image())->fake($dir, 200, 200),
'sort_order' => $this->faker->numberBetween(1, 10)
];
}
