Seeding Laravel many to many table with data
I have 3 tables; orders, products and order_product. I am trying to seed the order_product pivot table using the Seeder class.
This is what I have in my code;
$productArray = IlluminateSupportFacadesDB::table('products')->pluck('id')->toArray();
factory(AppOrder::class, 60)->create()->each(function ($order) use ($productArray) {
$randomPickings = mt_rand(1, 4);
$order->products()->sync(array_rand($productArray, $randomPickings));
});
I want attach product ids from the $productArray so an order can have, say, 1,2,3,4 or 5 products attached after seeding. Currently, I get this error when I run the seeder.
SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or
update a child row: a foreign key constraint fails
(`foo`.`order_product`, CONSTRAINT
`order_product_product_id_foreign` FOREIGN KEY (`product_id`)
REFERENCES `products` (`id`) ON DELETE CASCADE) (SQL: insert into
`order_product` (`order_id`, `product_id`) values (2, 0))
There's no product with id 0. I'm guessing it's picking the indexes instead of the values. How do I get the values selected/picked instead? Thanks.

syncaccepts one array and one boolean. You're passing a integer as the second parameter. Why?

@Phiter it was a typo from me. I have updated my question.

Can you do avar_dump(array_rand($productArray, $randomPickings))before syncing and see if all the IDs exist?

@Phiter This is what I have from the dump. gist.github.com/petersowah/59a2dff54d18153ccb139e252a3817ee
