I have a User model that hasOne profile and $with=['profile']

I have a Profile model that belongsTo user and $touches=['user']

I can't get them to save properly and return the results I'm looking for.

In my UserAPI I'm trying to save a new or existing user:

$user->fill($data);
$user->save();

I have to save here since I do some other stuff that requires the user id.

Then I create the profile:

if ($user->profile) {
    $profile = $user->profile;
} else {
    $profile = new Models\Profile;
}
$profile->fill($data_profile);

The next bit is where I have the issue. I've tried a few different ways:

A)

if (!$user->profile) {
    $profile->user()->associate($user);
    $user->setRelation('profile', $profile);
}
$profile->save();

That causes $user->toArray() to crash due to an infinite loop serializing $user->profile->user->profile->etc

B)

$user->profile()->save($profile);
if (!$user->profile) {
    $user->setRelation('profile', $profile);
}

But for some reason, before profile is save I have $user->profile but when saving $profile, it loads user which loads profile, so I get: $user->profile->user->profile But it stops there. I'm not sure why profile is loading user when it's saved. It only has a touch on the profile, not a with. Also, what caused me to notice all this to begin with, is it's not touching the user :/

C)

if (!$user->profile) {
    $profile->user_id = $user->id;
    $user->setRelation('profile', $profile);
}
$user->push();

This causes an infinite loop durring save, saves user, then profile, user, profile, etc.

It should work if it's a new user or a user update.

What am I doing wrong here?

A I got rid of a long while ago. B is what I've had but just realized it was loading extra stuff and editing the profile didn't update the user updated_at date, and C I just tried.

It's important that $profile touches $user.
