In Laravel, how do I retrieve a random user_id from the Users table for Model Factory seeding data generation?

if want to generate a random user_id from one of the user ID’s already stored in the user table. and you want to allow Laravel to choose a random user ID and insert into the database.

use following solution:

Try the below.

use App\User; // Assuming this is your User Model class with namespace.

$factory->define(App\Reply::class, function (Faker\Generator $faker) {
  return [
    'thread_id' => 1,
    'user_id' => User::all()->random()->id,
    'body' => $faker->paragraph
  ];
});

Remember that this gets all the user data from your table and then choses an id randomly. So if your table has huge amount of data, it is not recommended. Instead, in your Test Case, you can create a new User (via its own factory) and assign the id to the Reply object generated from the above factory.

Alternately, you can query for a specific user in the above factory definition.

'user_id' => User::where('username', 'like', 'test@user.com')->get()->random()->id

If you have a test user set up in your DB this will avoid pulling all the user data.
