This definitely isn't in the official documentation, but I've come across several occasions where it would be useful. Thank you again Povilas.

Love this, this actually helps a lot for some big projects where I needed to link together seeded data with ids!

Going to refactor my seeders into a tree structure and have nested calls like this.

You could go further and require command line arguments to get passed to it and throw errors if they're not set properly so that you can call groups of seeders easily!

I can see this is useful in a multi tenant app, the tenant can be created and passed into the seeder to associate every model with the tenant. Thanks!

Thanks this was very helpful! I was about to look up how to share variables between seeders!!

I could've used this yesterday – definitely implementing today!

Thanks Laravel Daily, I've been thinking how to implement this on my project. It's a big help.

Really useful, thanks! Is it possible to pass arguments from the command line when using artisan db:seed?

is there a way to pass directly the parameter from command line? something like this PHP artisan db:seed --class=someClass --user-id=1?

[PathOfDamn]

Does this method require user_id to be set inside $fillable attribute?

->each(function ($user)
{

}); is use elequoent relationship to seed database

here is how i do that

$category = [
'arduino' => Category::where('category', 'Arduino Family')->first(),
'raspberry' => Category::where('category', 'Raspberry Family')->first(),
'esp' => Category::where('category', 'ESP Family')->first(),
];

User::factory(20)
->create()
->each(function () use ($category) {
Product::factory(rand(10, 20))
->has(View::factory(rand(1, 3)))
->has(Price::factory(rand(3, 10)))
->has(Sell::factory(rand(1, 3)))
->has(Image::factory(rand(1, 5)))
->for($category[array_rand($category, 1)])
->create();
});
