Eloquent – inserting related models

In this question the accepted answer to saving related models was:

public function store(Request $request)
{
    $player->name = $request->input('name');
    $player->lastname = $request->input('lastname');
    $player->stats = [
      'position' => $request->input('stats.position'),
      'profile' => $request->input('stats.profile'),
    ];
    $player->save();
    return response()->json($player);
}

Whenever I try this I get an error:

Column not found: 1054 Unknown column ‘stats’ in ‘field list’

If I add stats to the guarded collection, it of course never comes in.

On my player object I have this:

public function stats(): HasMany
{
    return $this->hasMany(Stat::class);
}

So how can I have my stats come in, but elqoquent not attempt to use ‘stats’ as a column name in the insert?

Answer

Using the save() method, you can create a new Player object and save it, and then create a new Stat object and save it as a Player related stats():

$player = new Player
$player->name = $request->input('name');
$player->lastname = $request->input('lastname');
$player->save();

$stat = new Stat([
    'position' => $request->input('stats.position'),
    'profile' => $request->input('stats.profile'),
]);
$player->stats()->save($stat);
