You requested 1 items, but there are only 0 items available.
I have problem for example this test returns You requested 1 items, but there are only 0 items available. I was trying to dd($car) but i dont see anything in console what looks like dd of variable.
public function test_car_details_is_rendering_properly()
{
$user = User::factory()->create();
$this->actingAs($user);
$car = Car::factory()->create();
$response = $this->get("/cars/$car->id");
$response->assertStatus(200);
}
Level 1
public function show(Car $car)
{
Gate::authorize('view', $car);
$orders = ServiceOrders::with('cars')->get();
$doneOrders = [];
foreach($orders as $order) {
if(($order->is_done === 1) && ($car->id === $order->car_id)) {
$doneOrders[] = $order;
}
}
return view('cars.show', [
'car' => $car,
'doneOrders' => $doneOrders
]);
}

@raloseq What part of your code is giving that error "You requested 1 items, but there are only 0 items available"

@Sinnbeck hard to say im just doing php artisan test

@raloseq what does the rest of the stacktrace tell us?
Level 1
@tykus What do you mean by rest of the stacktrace? I don't see anything more in console.
Level 104
@raloseq you mean there is nothing after?

@tykus Oh this is the same error but for another test

@raloseq Any chance you are using random() inside one of your factories ?
Level 1
@Sinnbeck yes. i'm using
class CarFactory extends Factory
{
/**
* Define the model's default state.
*
* @return array<string, mixed>
*/
public function definition()
{
return [
'user_id' => User::all()->random()->id,
'type' => Type::all()->random()->name,
'model' => CarModel::all()->random()->name,
'VIN' => $this->faker->bothify('#################'),
'registration_number' => $this->faker->bothify('#######'),
'year' => $this->faker->date(),
];
}
}
Level 102
@raloseq So either Type or CarModel is empty (the tables), so you cannot get a random item. Create at least one of each before the factory for Car is run
1 like
Level 104
@raloseq why are you using name properties of Type and Model on the Car model; why are you not using ID foreign keys?
Level 1
@tykus I don't have relations there
Level 104
@raloseq you do have relationships, you just have not defined them!
Also, fetching all records is not particularly efficient; when you only need one, fetch only one:
'type' => Type::inRandomOrder()->first()?->name,
'model' => CarModel::inRandomOrder()->first()?->name,
1 like
Level 1
@tykus I have DatabaseSeeder like this
$this->call([
TypeSeeder::class,
CarModelSeeder::class,
UserSeeder::class,
EmployeeSeeder::class,
ClientSeeder::class,
CarsSeeder::class,
ServiceOrdersSeeder::class
]);
and if i do
'type' => Type::inRandomOrder()->first()?->name,
'model' => CarModel::inRandomOrder()->first()?->name,
it still gives me nothing
