phalcon 2.0.13 set data with magic setter to related model - php

Question

I have a problem with phalcon model magic getter and setter.
I want to update like this tutorial :
https://docs.phalconphp.com/en/latest/reference/models.html#storing-related-records
But the thing is my proj is multi module and separated models folder.
So I have to use alias for hasOne and belongsTo
$this->hasOne('user_id', '\Models\UserProfile', 'user_id', array('alias' => 'UserProfile'));
and
$this->belongsTo('user_id', '\Models\CoreUser', 'user_id', array('alias' => 'CoreUser'));
What i want to do is like this.
$CoreUser = new CoreUser();
$user = $CoreUser->findFirst(array(
//...condition here to find the row i want to update
));
$user->assign($newUserData);
$user->setUserProfile($newProfileData);
$user->update();
But above this code only save user data and don't save Profile data at all. (have profile data -- confirmed)
So do you have any idea what the error is? if u know, Please help me or give me a tip.

Answer 1

I got it now.. when assigning like $user->UserProfile = $newUserProfile;
$newUserProfile should b a Model Object.
So my new code is
$CoreUser = new CoreUser();
$user = $CoreUser->findFirst(array(
//...condition here to find the row i want to update
));
$profile = $user->UserProfile; //$profile is now model object which related to $user
//assign new array data
$profile->assign($newProfileData);
$user->assign($newUserData);
/*
* can also assign one by one like
* $user->first_name = $newProfileData['first_name'];
* but cannot be like $profile = $newProfileData or $user->UserProfile = $newProfile
* since it's gonna override it the model with array
*/
$user->UserProfile = $profile;
$user->update(); // it's working now
Thanks to #Timothy for the tips too .. :)

Instead of doing
$profile = $user->UserProfile;
You should instantiate a new UserProfile object
// find your existing user and assign updated data
$user = CoreUser::findFirst(array('your-conditions'));
$user->assign($newUserData);
// instantiate a new profile and assign its data
$profile = new UserProfile();
$profile->assign($newProfileData);
// assign profile object to your user
$user->UserProfile = $profile;
// update and create your two objects
$user->save();
Note that this will always create a new UserProfile. If you want to use the same code to update and create a UserProfile, you can maybe do something like:
// ...
// instantiate a (new) profile and assign its data
$profile = UserProfile::findFirstByUserId($user->getUserId());
if (!$profile) {
$profile = new UserProfile();
}
$profile->assign($newProfileData);
// ...
