Adding Relations to Laravel Factory Model

I'm trying to add a relation to a factory model to do some database seeding as follows - note I'm trying to add 2 posts to each user

public function run()
{
   factory(AppUser::class, 50)->create()->each(function($u) {
         $u->posts()->save(factory(AppPost::class, 2)->make());
   });
}

But its throwing the following error

Argument 1 passed to IlluminateDatabaseEloquentRelationsHasOneOrMany::s  
ave() must be an instance of IlluminateDatabaseEloquentModel, instance 
of IlluminateDatabaseEloquentCollection given

I think its something to do with saving a collection. If re-write the code by calling each factory model for the post separately it seems to work. Obviously this isn't very elegant because if I want to persist 10 or post to each user then I'm having to decalare 10 or lines unless I use some kind of for loop.

public function run()
{
   factory(AppUser::class, 50)->create()->each(function($u) {
     $u->posts()->save(factory(AppPost::class)->make());
     $u->posts()->save(factory(AppPost::class)->make());
   });
}

* UPDATED *

Is there any way to nest the model factory a 3rd level deep?

public function run()
{
   factory(AppUser::class, 50)
       ->create()
       ->each(function($u) {
           $u->posts()->saveMany(factory(AppPost::class, 2)
                    ->make()
                    ->each(function($p){
                          $p->comments()->save(factory(AppComment::class)->make());
          }));
   });
}

Try this. It worked for me:

factory(AppModelsAuthUser::class, 300)->create()->each(function ($s) {
                    $s->spots()->saveMany(factory(AppModelsSpotsParking::class, 2)->create()->each(function ($u) {
                            $u->pricing()->save(factory(AppModelsPaymentPricing::class)->make());
                    }));
                    $s->info()->save(factory(AppModelsUserData::class)->make());
            });

对于第三级嵌套关系，如果要使用适当的相应外键创建数据，则可以循环创建帖子的所有结果，如下所示：

factory(AppUser::class, 50)->create()->each(function($u) {
    $u->posts()
        ->saveMany( factory(AppPost::class, 2)->make() )
        ->each(function($p){
            $p->comments()->save(factory(AppComment::class)->make());
        });
});
