Replace this
$round = Round::factory()->create(['user' => $user,]);
with this
$round = Round::factory()->create(['user_id' => $user->id]);

Pass variable to factory, Laravel 8, not working
Trying to pass a variable from DatabaseSeeder to factory in Laravel 8; is there new syntax?
I need to loop thru my users with foreach. I see a bunch of examples of passing variable to a factory as an array like this
// DatabaseSeeder.php
foreach ($users as $user) {
$round = Round::factory()->create(['user' => $user,]);
}
and I've also seen this:
$round = Round::factory()->create($user);
Most of those examples are several years old, but one is Sep'19. But neither way is working for me. I get:
// Terminal: php artisan db:seed
Illuminate\Foundation\Bootstrap\HandleExceptions::handleError("Undefined variable: user", …
My foreach loop is definitely producing valid $user (confirmed via dd($user)). My factory def looks like this:
// RoundFactory.php
return [
'user_id' => $user,
'other_field' => $this->faker-> …something,
other fields …
]
So is there some other way to achieve this? Thanks.

Thanks for replying. Your suggestion in the seeder is correct, but it seems my problem was in the factory definition array. My mistake was repeating the variable $user in the factory definition array,
'user_id' => $user->id.
So I've changed my factory def to say
'user_id' => 'overridden'
to remind me that the $user variable doesn't work.

Hard to figure that from what you've shown.

Not sure what you mean. I kept my reply short for time. I used your code in the DatabaseSeeder, but I had to change the RoundFactory definition as below to fix the error.
My RoundFactory definition now reads:
return [
'user_id' => 'overridden' // overridden is placeholder replaced by 'user_id' value from seeder
// 'user_id' => $user // This $user variable was my original code, was causing the error
(other fields)
The new code has worked so far, but I would appreciate any comment you have on it. Thanks much.

Yap, truncating your posts made impossible to give you better answer.

I know this post is 1 year old but for the benefit of others that may come across this thread, there is a built-in way to accomplish what the OP is wanting with the relationship. Assuming that the Round model has a user relationship on it, you can do this:
$round = Round::factory()->for($user)->create();
Then in the factory, you can can have this:
return [
'user_id' => User::factory() // This will still get overwritten but it will allow for a user to be created if it is not overwritten
(other fields)
