Defining Laravel foreign keys with Model Factories, One to One & One to Many Relationships without creating unnecessary models

Question

Recently I have been trying to seed my database using Laravel seeding through Model Factories and Faker.

For simple schemas, it is just a breeze to have it working :). H

Answer 1

So here is my solution:

The example deals with:

• Users & Profiles (for illustrating One to One relationships)

• Users & Posts (for illustrating One to Many relationships)

  // ONE TO ONE relationship (with Users already created)
  $factory->define(App\Profile::class, function (Faker\Generator $faker) {
      return [
          'user_id' => $faker->unique()->numberBetween(1, App\User::count()),
          // Rest of attributes...
      ];
  });
  
  // ONE TO MANY relationship (with Users already created)
  $factory->define(App\Posts::class, function (Faker\Generator $faker) {
      $users = App\User::pluck('id')->toArray();
      return [
          'user_id' => $faker->randomElement($users),
          // Rest of attributes...
      ];
  });
